Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments, but not all embodiments, of the technical solutions of the present application. All other embodiments obtained by a person skilled in the art without any inventive step based on the embodiments described in the present application are within the scope of the protection of the present application.

Some concepts related to the embodiments of the present application are described below.

Online documentation: the Document can be edited by multiple persons at the same time, and various types such as online Word/Excel/PPT (powerPoint, presentation)/PDF (Portable Document Format)/collection table and the like are supported. The document can be checked and modified at any time and any place on various devices such as a computer side (personal computer (PC) client side, an online document webpage version), a mobile side (online document Application (App), an online document applet) and a notebook computer. The webpage can be viewed and edited by opening the webpage, the cloud end can be stored in real time, and the authority is safe and controllable.

A typesetting engine: the composition engine of the web browser is also called a page rendering engine, and is responsible for acquiring content (HTML (HyperText Markup Language), XML (eXtensible Markup Language), images, etc.) of a web page, collating information (for example, adding CSS (Cascading style sheets), etc.), and calculating a display mode of the web page, and then outputting the display mode to a display or a printer. All web browsers, email clients, and other applications that require editing and displaying web content require a composition engine.

CSS: is a computer language used to represent the style of files such as HTML or XML. The CSS can not only statically modify the web page, but also dynamically format elements of the web page in coordination with various scripting languages. The CSS can accurately control the typesetting of element positions in the webpage at a pixel level, supports almost all font and font styles and has the capability of editing webpage objects and model styles.

DOM (Document Object Model): is a standard programming interface for processing extensible markup languages. It is a platform and language independent API (Application programming Interface) that can dynamically access programs and scripts to update their content, structure, and style of www (World Wide Web) documents (currently, HTML and XML documents are defined by declarative parts). The document may be further processed and the results of the processing may be added to the current page. The DOM is a tree-based API document that requires that the entire document be represented in memory during processing. When the browser loads an HTML file through the network or the local file system and finishes analyzing the HTML file, the kernel generates the most important data structure of the HTML file: and (4) a DOM tree. Each node on the DOM tree corresponds to each element in the web page, and the web page can dynamically change its structure by operating the DOM tree through JavaScript. The rendering layer in the document editor in the embodiment of the application can realize the rendering of the document view by using the DOM.

canvas element: for rendering 2D (two-dimensional) graphics and images on web pages. The HTML5< canvas > tag is used to draw images (by script, usually JavaScript). However, the < canvas > element itself has no rendering capabilities (it is simply a container for graphics) and must use scripts to accomplish the actual rendering task. The getContext () method may return an object that provides methods and properties for drawing on the canvas, may be used to draw text, lines, rectangles, circles, and the like on the canvas. The rendering layer in the document editor in the embodiment of the present application may use the covas to implement the rendering of the document view.

content table (content edit): is a local native component for rich text editing on a web browser. web online editors are implemented in two forms: one based on iframe (HTML tag) and the other based on contentdigital. The contentdigital attribute is set for the element, which can be made editable within the area of the element. The document editor in the related art uses the content directory capability of the browser to render the document view.

ScrollTop: the scrollTop value of an element is a measure of the distance from the top of the content of the element (rolled up) to the (top of the) visible content of its viewport. When the content of an element does not produce a vertically oriented scroll bar, its scrollTop value is 0. In the embodiment of the application, the scroll value of the display area of the document view when the cursor is kept at the first position can be set through scrollTop; and adjusting the document view display area according to the scroll value to adjust the display content in the second document view.

The following briefly introduces the design concept of the embodiments of the present application:

with the continuous development of network application technology, the application of network office class brings great convenience to daily office of enterprises. Online documents are an emerging network office application. For example, a creator of an online document may submit a document to a server after creating a document and filling in or updating the document content in the document that needs to be processed by other users; meanwhile, the creator of the document sends the link of the document to other users or a group where the other users are located through the instant messaging application, the other users can open the document by clicking the link, and the document contents which need to be processed respectively are searched in the opened document.

However, in the implementation of the document editor in the related art, it is mostly employed to implement the basic editing capability based on the contentdigital capability provided by the browser. The view of the user is changed continuously due to the editing of other people, the window of the user needs to be adjusted continuously, the purpose of common cooperation is achieved, the experience is very poor, and the office efficiency is low.

In view of the above, the present application provides a method and an apparatus for controlling display of an online document, an electronic device, and a storage medium. The method for calculating the view position during editing of the online document, which is provided by the embodiment of the application, particularly means that when a user edits a document with others at the same time, the region being edited by the user can be calculated according to the cursor position, the region can not be changed due to editing by others, and the problem that pages continuously jump during co-editing is reduced, so that the coordination capacity of the online document can be improved, and the office efficiency is improved.

The preferred embodiments of the present application will be described below with reference to the accompanying drawings of the specification, it should be understood that the preferred embodiments described herein are merely for illustrating and explaining the present application, and are not intended to limit the present application, and that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Fig. 1 is a schematic diagram of an application scenario of online content display in an embodiment of the present application, where the application scenario includes a plurality of terminal devices and a server, and each terminal device may communicate with the server 130 directly or indirectly. In fig. 1, the user a corresponds to the first terminal device 110, and the user B corresponds to the second terminal device 120, which does not actually limit the number of terminal devices. In some cases, the terminal devices may communicate with each other through the server 130 first, direct communication may be established between the terminal devices, and the manner of direct communication between the terminal devices may be referred to as point-to-point communication.

Among them, each terminal device may have an online document application installed therein, and for simplicity of description, the online document application installed in the first terminal device 110 may be referred to as a first online document application 111, and the online document application installed in the second terminal device 120 may be referred to as a second online document application 121. The online document application related to the embodiment of the application may be a software, or a client such as a web page or an applet, and the server is an online document server corresponding to the software, or the web page or the applet, and the specific type of the client is not limited.

In an alternative embodiment, the communication network is a wired network or a wireless network. The terminal device and the server may be directly or indirectly connected through wired or wireless communication, and the application is not limited herein.

In this embodiment, the terminal device is an electronic device used by a user, and the electronic device may be a computer device having a certain computing capability and running instant messaging software and a website or social contact software and a website, such as a personal computer, a mobile phone, a tablet computer, a notebook, an e-book reader, and the like. Each terminal device passes through a wireless Network and a server, the server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, a cloud function, cloud storage, Network service, cloud communication, middleware service, domain name service, security service, Content Delivery Network (CDN), big data, an artificial intelligence platform, and the like.

The target online document in the embodiment of the application is stored on the online document server, and any plurality of terminal devices with access rights can access the target online document and simultaneously or non-simultaneously perform processing operations, such as editing operations, viewing operations and the like, on the target online document. The content update of any terminal device to the online document can be synchronized to other terminal devices, so as to ensure the content consistency of the target online document on all the terminal devices.

It should be noted that, when processing the target online document, the terminal device displays a cursor in the document view, where the cursor is used to prompt the user of the position of the content being edited in the target online document. In the related art, for a certain terminal device, the cursor may be at a certain position in the document when the terminal device processes the target online document, but when the terminal device receives the content update of the target online document from other terminal devices, the document view displayed by the terminal device may continuously jump along with the increase or decrease of the content of the target online document by other terminal devices, resulting in low processing efficiency of the online document. The embodiment of the application provides a method for adjusting a document view based on a cursor position when an online document is edited, so that when multiple persons edit a target online document together, an area being edited by a target object is not subjected to editing by other cooperative objects, the cooperative capability of the online document is improved, and the processing efficiency of the online document is improved.

Referring to fig. 2, an implementation flow chart of a display control method for an online document provided in the embodiment of the present application is applied to an online document application, and a specific implementation flow of the method is as follows:

s21: updating the content edited by the target object in the display area of the document view and controlling the display position of a cursor in the document view according to the editing operation of the target object in the target online document, wherein the target online document is an online document which can be edited cooperatively;

the target online document can be a plurality of types such as Word/Excel/PPT/PDF/collection table which can be edited by multiple persons. When the online document application used by the target object responds to the editing operation, triggered by the target object through the document view, aiming at the target online document, the online document application also sends the change content aiming at the target online document to the online document server, and after receiving the change content, the online document server generates the content updating information aiming at the target online document according to the change content and sends the content updating information to the online document application used by the cooperative object for cooperatively editing the target online document with the target object.

For example, if the online document application used by the target object is the first online document application 111, only one collaborative object for editing the target online document in collaboration with the target object is provided, and the online document application used by the collaborative object is the second online document application 121, when the target object edits the target online content through the first online document application 111, the first online document application 111 updates the content edited by the target object in the document view display area and controls the display position of the cursor of the target object in the document view according to the editing operation of the target object in the target online document.

In addition, the first online document application 111 needs to send the changed content of the target online document when the target object performs the editing operation to the online document server, and after receiving the changed content, the online document server generates content update information for the target online document according to the changed content, and sends the content update information to the second online document application 121, so that the second online document application 121 adjusts the display content of the document view display area according to the received content update information.

As shown in fig. 3A, the portion of the dashed box S30 indicates that there are two users currently editing the target online document, and the document view display area is the portion shown by the dashed box S31 in fig. 3A, and assuming that the two users are the target object and one collaboration object, the current cursor position of the target object is shown as S32 and the current cursor position of the collaboration object is shown as S33.

It should be noted that, when the document view display area is displayed in full screen, the document view display area may occupy the entire screen of the terminal device. And the document view display area may occupy a portion of a screen of the terminal device, etc., when the document view display area is enlarged or reduced. In addition, the document view display area may also be embedded in an operation interface of a certain application, in which case the document view display area may be a designated area in the operation interface of the application, and the like, and is not specifically limited herein.

S22: and adjusting the content edited by the at least one cooperative object in the document view display area according to the editing operation of the at least one cooperative object on the target online document so as to keep the cursor at a first position, wherein the first position is the display position of the cursor in the first document view, and the first document view is the document view displayed in the front document view display area.

In the embodiment of the application, when at least one cooperative object collaboratively edits a target online document with a target object, an online document application of the cooperative object responds to an editing operation, triggered by a document view, of the cooperative object for the target online document, and then sends changed content for the target online document to an online document server, and after receiving the changed content, the online document server generates content update information for the target online document according to the changed content, and sends the content update information to other cooperative objects and the online document application of the target object. At this time, the online document application of the target object may adjust the content edited by the at least one collaborative object in the document view display area in a state that the cursor is kept at the first position according to the editing operation of the at least one collaborative object on the target online document. Similarly, the online document application for other collaborative objects adjusts the document view in this way.

Still taking the above-mentioned enumerated embodiment as an example, since only the target object and one collaboration object are currently editing the target online document cooperatively, when the second online document application 121 responds to the editing operation for the target online document triggered by the collaboration object, the second online document application 121 sends the change content for the target online document when the collaboration object performs the editing operation to the online document server, and after receiving the change content, the online document server generates the content update information for the target online document according to the change content and sends the content update information to the first online document application 111, so that the first online document application 111 adjusts the display content of the document view display area according to the received content update information.

The first document view refers to a document view displayed in the document view display area before the online document application of the target object has not adjusted the content edited by the at least one collaborative object in the document view display area, for example, the document view in the document display area shown in fig. 3A is a first document view shown in the embodiment of the present application, and S32 shown in fig. 3A is a display position, that is, a first position, of a cursor of the target object in the first document view before adjustment.

Referring to FIG. 3B, a diagram of an adjusted document view is shown in an embodiment of the present application. As can be seen from FIG. 3B, after the edited content of the at least one collaboration object is adjusted in the document view display area according to the editing operation of the at least one collaboration object on the target online document, it is still ensured that the cursor of the target object is at the first position, as shown at S34 in FIG. 3B, where S34 is the same as the first position S32 shown in FIG. 3A.

As can be seen from fig. 3A and 3B, in the embodiment of the present application, when a user edits a target online document, if there are other users who have added or subtracted other rows or other previous height changes when editing the target online document, the document view of the user does not change along with the addition or subtraction of the target online document content by other users, but the view is fixed with the cursor position of the user as the focus. Therefore, when the user collaboratively edits the online document with other people, the document view does not need to be continuously adjusted, the collaboration capability of the online document is improved, and the processing efficiency of the online document is further improved.

In an alternative embodiment, S22 may be implemented according to the flowchart shown in fig. 4, which specifically includes the following steps:

s400: when content updating information sent by an online document server is received, first position information of a cursor in a first document view is obtained, and the content updating information is sent according to editing operation of at least one cooperative object on a target online document;

that is to say, in the embodiment of the present application, when the online document application used by the target object receives the content update information sent by the online document server, it indicates that the online document application monitors that there are other collaborative objects collaboratively editing the target online document with the target object, and at this time, first position information of a first position of a cursor of the target object in a first document view at the current time, for example, coordinates of the cursor in the first document view, is first obtained.

Optionally, the first position information of the first position is obtained from the composition engine provided in the embodiment of the present application. When typesetting, the typesetting engine in the embodiment of the present application still follows the established rules, which may be the same as the typesetting rules in the related art, and is not limited herein.

When the online document server receives the edited content of the target online document sent by the online document client of at least one cooperative object, the online document server can generate an online document change message aiming at the target online document according to the changed content and send the online document change message to the online document application of the target object.

S401: typesetting the target online document according to the content updating information, and determining second position information of a second position of the second document view after the cursor is typeset;

in the embodiment of the application, after receiving the content update information sent by the online document server, the online document application of the target object may adjust the content of the target online document according to the update information, and perform typesetting on the target online document.

Finally, after the target online content is typeset based on the content updating information, the display position of the cursor in the second document view obtained by adjusting the target online document at the moment is determined, and corresponding second position information, such as the coordinate of the cursor in the second document view, is obtained.

As shown in fig. 3C, assuming that the collaborative object has several lines of content added, the second document view obtained by laying out the target online document is shown in fig. 3C, where the position shown by the dashed box S35 is the second position, that is, the display position of the cursor of the target object in the second document view obtained by laying out again.

It should be noted that the target object and the collaborative object may edit the target online document at the same time, and at this time, the online document application of the target object updates the content edited by the target object in the document view display area according to the editing operation of the target object in the target online document, and at the same time, adjusts the content edited by the collaborative object in the document view display area according to the received content update information sent by the online document server.

Optionally, before step S401, content update information of the target object with respect to the content update information of the target online document may be further acquired. Furthermore, when step S402 is executed, the target online document is typeset according to the content update information of the at least one coordination object for the target online document and the content update information of the target object for the target online document, and the second position information of the second document view after the cursor is typeset is determined.

For example, two lines of contents are added to the target object, three lines of contents are added to the collaborative object, wherein the content update information of each object for the target online document contains text information (or text information of deleted contents), position information and the like of the newly added contents.

Optionally, the process of typesetting the target online document is implemented by the typesetting engine, so that the content update information of the target online document needs to be sent to the typesetting engine, the typesetting engine finishes typesetting the target online document according to the content update information, and after the typesetting is finished, the second document view and the second position information of the second position displayed by the cursor in the second document view can be further obtained from the typesetting engine.

If the target object and the collaborative object edit the target online document at the same time, the content updating information of the target online document is also required to be sent to a typesetting engine, and the content updating information of the target object aiming at the target online document is obtained; and sending the content update information of the target online document and the content update information of the target online document of the at least one cooperative object to a typesetting engine, and typesetting by the typesetting engine, for example, sending the content update information of two newly added lines of content of the target object and three newly added lines of content of the cooperative object to the typesetting engine.

In the embodiment of the present application, the second document view is obtained after the typesetting engine rearranges the target online document according to the content update information of the target online document.

As can be seen from the above, after the typesetting is performed again, the position of the cursor of the target object is also changed, and if the document view is directly rendered, the view may jump, so that the embodiment of the present application anchors the view according to the position of the cursor, and adjusts the display content of the second document view according to the position of the cursor before the rendering, which is specifically implemented based on step S402 and step S403.

S402: adjusting the display content of the second document view according to the first position information and the second position information, and adjusting the display position of the cursor to a first position;

in an optional implementation manner, when the display content in the second document view is adjusted according to the first position information and the second position information, the specific process is as follows:

obtaining a scroll value for the document view display area when the cursor is kept at the first position according to the first position information and the second position information; and adjusting the document view display area according to the scroll value to adjust the display content in the second document view, and ensuring that the cursor of the target object is kept at the first position after the display content is adjusted.

That is, when adjusting the display content in the second document view, the effect of compensating the position offset of the cursor is substantially achieved by the scroll value calculated by the first position information and the second position information, and therefore, after adjusting the document view based on the scroll value, when the cooperative object and the target object cooperatively edit the target online document, the cursor of the target object can be kept at the first position, and the document view does not jump along with the editing of the target online document by the cooperative object, so that the cooperative capability and the processing efficiency of the online document can be improved.

S403: and rendering the document view and the cursor in the document view display area according to the display content and the first position information.

In the embodiment of the present application, when rendering a document view in a document view display area according to display content, the document content needs to be rendered in the document view display area, that is, a text that needs to be displayed in a target online document is rendered in the document view display area, where the text that needs to be displayed is a text that is displayed in the document view display area after scrolling the document view according to the above listed scroll values. In addition, the display style of the document view may be rendered according to a CSS file or the like.

In addition, in the embodiment of the application, when the document view is rendered, the position of the cursor in the document view display area can be determined according to the first position information, and the cursor is drawn at the determined position, so that the cursor can be ensured to be kept at the first position. Because the cursor in the embodiment of the application is drawn according to the first position information, but not a cursor model provided by a document editor of the online document application, the cursor in the related art cannot be drawn in the rendering process, but a model provided by the related document editor is directly adopted, the position of the cursor cannot be acquired before rendering, but the position of the cursor in the embodiment of the application can be acquired before rendering after typesetting, and then drawing is performed according to the determined position information in the rendering process, the position of the cursor is maintained, and the coordination capability of the online document is improved based on the cursor anchoring view.

It should be noted that, when rendering the document view and the cursor, the rendering engine provided in the embodiment of the present application may be used to implement the rendering, send the determined display content and the first position information to the rendering engine, and render the document view and the cursor in the document view display area based on the rendering engine.

In an alternative embodiment, when the scroll value for the document view display area when the cursor is held at the first position is obtained based on the first position information and the second position information, the difference between the coordinate value in the vertical direction in the second position information and the coordinate value in the vertical direction in the first position information may be used as the scroll value for the document view display area when the cursor is held at the first position.

It is assumed that the first position information may be represented as (x1, y1) and the second position information may be represented as (x2, y2), where x1 and x2 represent coordinates of the cursor in the horizontal direction (x direction) and y1 and y2 represent coordinates of the cursor in the vertical direction (y direction).

At this time, assuming that the coordinate value in the vertical direction in the first position information is y1 ═ prevOffsetY, and the coordinate value in the vertical direction in the second position information is y2 ═ offsetY, the scroll value scrollTop is offset-prevOffsetY, and in the embodiment of the present application, the scroll value may be set by the DOM, and the display content of the document view display area is adjusted.

In the above embodiment, the scroll value scrollTop may be calculated in advance according to the y-direction offsets of the cursor twice before and after the content typesetting edited by another person, and the DOM sets the scrollTop (the scroll value of the DOM) to compensate the y-direction offset of the cursor position, thereby achieving the effect of visually anchoring the view.

It should be noted that, in the above embodiments, the target object and one collaborative object are exemplified to edit the target online document at the same time, and the same reason is also used when the target object and multiple collaborative objects edit the target online document at the same time, and no repeated description is given here.

In an alternative embodiment, when the display content of the document view display area is adjusted according to the scroll value, the following two cases are specifically distinguished:

in case one, the scroll value is a positive number, and at this time, the document view display area needs to be scrolled downward in the vertical direction, and the scroll distance is the same as the scroll value.

For example, the editing operation of the collaboration object on the target online document is to add several lines of content to the target online document, in this case, for the target object, the second position of the cursor in the adjusted second document view should be moved downward with the added several lines of content compared with the first position in the first document view before adjustment, and the offset-prevoffset is a positive value, so that after the document view display area is scrolled downward in the vertical direction, and the scrolling distance is offset-prevoffset, it can be ensured that the cursor of the target object is still located at the position in the first document view before adjustment after the content edited by at least one collaboration object is adjusted in the document view display area.

And in the second case, the scroll value is a negative number, the document view display area is scrolled upwards along the vertical direction, and the scroll distance is the absolute value of the scroll value.

For example, the editing operation of the collaboration object on the target online document is to delete several lines of content of the target online document, in this case, for the target object, the second position of the cursor in the adjusted second document view should be moved upward following the deleted several lines of content compared with the first position in the first document view before adjustment, and the offset-prevoffset is a negative value, so that after the document view display area is scrolled upward in the vertical direction, and the scrolling distance is prevoffset-offset, it can be ensured that the cursor of the target object is still located at the position in the first document view before adjustment after the content edited by at least one collaboration object is adjusted in the document view display area.

It should be noted that the first document view in this embodiment of the present application refers to a document view displayed in a document view display area before the online document application typesets the editing operation of the target online document according to at least one collaborative object, and the first position is a display position of a cursor of the target object in the first document view; the second document view is a document view displayed in a document view display area obtained after the online document application typesets the editing operation of the target online document according to the at least one cooperative object, and the second position is a display position of a cursor of the target object in the second document view.

In the above embodiment, the display area of the document view is adjusted by the y-direction offset of the cursor twice before and after the layout to achieve the effect of compensating the y-direction offset of the cursor position, and the view can be ensured to be visually anchored, so that when the target object and at least one collaborative object collaboratively edit the target online document, the position of the cursor of the target object can be kept from being affected by the content edited by the collaborative object, the document view of the target object does not jump along with the increase or decrease of the content of the target online document by the collaborative object, and the effect of fixing the document view with the cursor position of the target object as the focus is achieved.

In the following, an online document application is taken as an example of a browser, and in this case, the document view is a web page view. Fig. 5 is a flowchart illustrating a complete method of controlling display of an online document on a browser side according to an embodiment of the present application. The specific implementation flow of the method is as follows:

step S51: monitoring the content change of a target online document by an online document application;

step S52: after monitoring that the content of the online document is changed, the online document application judges whether the current change is that the user and others cooperate, if so, the step S53 is executed; otherwise, return to step S51;

step S53: caching the position prevOffsetY of the current cursor in the vertical direction by the online document application;

step S54: detecting the end of typesetting generated by the change of others by the online document application;

step S55: the online document application acquires the latest offset of the current cursor in the vertical direction;

step S56: the online document application determines whether offset is the same as prevoffset, and if so, returns to step S51, otherwise, executes step S57;

step S57: the online document application modifies the scroll value scrollTop of the current DOM, and adds up (offset-prevoffset) the current scrollTop;

step S58: the online document application triggers the rendering process to render the document view and cursor, and returns to step S51 after rendering is complete.

In step S52, there may be two cases when the online document application monitors that the document content is changed, where one case is that the online document application detects the editing operation of the target object on the target online document, and the other case is that the content of the online document receives the content update information for the target online document returned by the online document server, which indicates that at least one collaborative object triggers the editing operation for the target online document by the online document application.

In this step, it is necessary to determine whether the current change is due to collaboration of the user with another person, that is, whether at least one collaboration object exists to perform an editing operation on the target online document, that is, the embodiment of the present application is applicable to a case where the target object and the at least one collaboration object jointly edit the target online document, and if only the target object edits the target online document, the display content of the document view display area may not be adjusted in the manner in the embodiment of the present application, or the document view may be rendered in the manner listed in the embodiment of the present application, that is, in addition to rendering the document content in the document view display area according to the display content, the position of the cursor in the document view display area may be determined according to the first position information, and the cursor may be drawn at the determined position.

It should be noted that, in this embodiment of the application, the online document server may send the changed content of the target online document to the corresponding online document application (browser) in real time through the online document change message, and the specific process is as follows:

when the cooperative object edits the target online object, the online document client used by the cooperative object submits the edited content to the online document server, and the online document server pushes the edited content to other cooperative objects and the target object. Taking the target object as an example, after the online document application used by the target object receives a push message sent by the online document server, the online document application will trigger the typesetting and rendering processes, where the push message includes content update information.

The typesetting comprises the step of updating the content edited by the target object according to the editing operation of the target object on the target online document or adjusting the content edited by the cooperative object according to the content updating information sent by the online document server.

It should be noted that, in the embodiment of the present application, each time the online document application receives content update information sent by the online document server, the composition and rendering are triggered.

In addition, the method for controlling display of an online document in the embodiment of the present application has an important premise that, in the embodiment of the present application, the position of the cursor can be known in advance before rendering by the browser, that is, after the composition is performed by the composition engine, the position of the cursor is obtained before rendering by the rendering layer rendering engine, and then the display content of the document view is adjusted based on the cursor, corresponding to the composition process in step S53.

In the related art, in the implementation of a document editor, it is mostly adopted to implement a basic editing capability based on a content directory capability provided by a browser. In the implementation of the browser, developers do not need to care about the whole process from the input of characters to the final rendering of the characters into a user view, and basic capability support is provided for the typesetting and rendering of the characters by the browser. However, based on the capability of the browser to provide text composition and rendering, the browser does not provide a programmable API between composition and rendering, i.e., the developer cannot intervene in the process between the text composition and rendering of the browser. And thus the position of the cursor cannot be obtained in advance before rendering.

In the implementation of the embodiment of the present application, the latest position of the cursor must be obtained after the typesetting and before the rendering to calculate the distance that the document view needs to be scrolled, which is because if the latest position of the cursor is obtained after the rendering, the whole document view will be rendered twice, and jitter occurs, which affects the user experience. Therefore, the document editor in the related art cannot realize the anchor view function similar to the embodiment of the application, or although the view can be anchored, the document editor generates visual jitter and experiences worse.

The document editor provided by the embodiment of the application is different from the related technology, the document editor kernel in the application is completely independently developed, and the realization of the traditional content table scheme is abandoned, so that the editing area is completely controllable. The overall architecture is shown in fig. 6.

Fig. 6 is a schematic diagram illustrating a structure of a document editor according to an embodiment of the present disclosure. The document editor in the embodiment of the present application includes: the system comprises an input layer, a data layer, a typesetting engine and a rendering layer.

The user can edit or adjust the style of a document view or the text of a target online document through the input layer, and the method further comprises the steps of setting the display of a cursor, selecting a region and the like; the data layer is used for processing the data input by the user through the input layer, and then the document can be typeset through the typesetting engine. After typesetting, the rendering of the document view can be performed through the rendering layer.

The document editor in the embodiment of the application takes over the realization of the typesetting and rendering of the browser, and the typesetting engine and the rendering layer which are independently researched and developed are adopted, so that the latest position of the cursor can be known in advance according to the information provided by the typesetting engine before rendering, and whether difference value rolling is needed or not is determined, and the finally displayed view is ensured to be a view anchoring the cursor.

The specific process is as follows: when content updating information sent by an online document server is received, first position information of a first position is obtained from a typesetting engine; and then sending the content updating information of the target online document to a typesetting engine through a data layer, and obtaining a second document view and second position information of a second position displayed by a cursor of the target object in the second document view from the typesetting engine after typesetting based on the typesetting engine, wherein the second document view is obtained after the typesetting engine typesets the target online document again according to the content updating information of the target online document.

In the embodiment of the application, after the typesetting based on the typesetting engine and before the rendering by the rendering engine, the display content of the second document view can be adjusted according to the first position information and the second position information, and the display position of the cursor is adjusted to the first position; the specific implementation mode is as follows: the difference between the coordinate offsetY in the vertical direction in the second position information and the coordinate prevOffsetY in the vertical direction in the first position information is calculated and used as a scroll value scrollTop, and the scrollTop is set by the DOM to compensate the y-direction offset of the cursor position.

After the display content of the second document view is adjusted, the adjusted display content and the first position information are sent to the rendering engine, and the document view and the cursor are rendered in the document view display area through the rendering engine, so that the cursor is still kept at the first position in the rendered document view, as shown in fig. 3B, and the effect of visually anchoring the view is achieved.

Therefore, when the user edits the online document in cooperation with other people, the document view of the user can not be edited by other people, the problem of jitter is avoided, the user does not need to adjust the document view back and forth, and the processing efficiency of the online document is improved.

When the document view is rendered through the rendering layer, the rendering layer can be divided into two parts, wherein one part is DOM and the other part is canvas. The DOM is a standard programming interface for processing an extensible markup language in an embodiment of the present application. Programs and scripts can be dynamically accessed based on the DOM to update its content, structure, and style of the www document. Whereas canvases are mainly used for drawing 2D graphics and images on web pages, such as drawing text, lines, rectangles, circles, and so on.

In particular, the DOM is a tree-based API document that requires that the entire document be represented in memory during processing. When the browser loads an HTML file through the network or the local file system and finishes analyzing the HTML file, the kernel generates the most important data structure of the HTML file: and (4) a DOM tree. Each node on the DOM tree corresponds to each element in the web page, and the web page can dynamically change its structure by operating the DOM tree through JavaScript. The rendering layer in the document editor in the embodiment of the application can realize the rendering of the document view by using the DOM. However, the DOM tree itself cannot be directly used for typesetting and rendering, the kernel generates another tree, a Render tree, each node, Render object, in the Render tree is almost in one-to-one correspondence with the node in the DOM tree, and when a visible DOM node is added to the DOM tree, the kernel generates a corresponding Render object for the visible DOM node to be added to the Render tree. The Render tree is a main job object of the browser composition engine, the composition engine determines the final structure of the Render tree according to the preset composition rule according to the style definition of the DOM tree and the CSS style sheet, including the size and the position of each Render object, and one composed Render tree is the main input of the rendering engine of the rendering layer of the browser. In the embodiment of the application, the cursor of the target object can be used as a node in the DOM tree, and the cursor is drawn based on the DOM at the rendering layer.

Referring to fig. 7, an implementation flow chart of a method for controlling display of an online document according to an embodiment of the present application is applied to an online document server, and a specific implementation flow of the method is as follows:

s71: obtaining updated content of at least one collaborative object after editing operation is carried out on a target online document through an online document application, wherein the target online document is an online document capable of being edited collaboratively;

s72: and generating content updating information aiming at the target online document according to the content of the target online document updated by the at least one cooperative object, and sending the content updating information to the online document application of the target object, so that the online document application of the target object adjusts the content edited by the at least one cooperative object in the document view display area according to the content updating information to keep the cursor at a first position, wherein the first position is a display position of the cursor in a first document view, and the first document view is a document view displayed in the front document view display area.

In the foregoing embodiment, when the target object and at least one collaborative object edit the target online document at the same time, the document view corresponding to the target object does not change along with the increase or decrease of the collaborative object to the content of the target online document, but the document view is fixed with the cursor position of the target object as a focus.

Referring to fig. 8, an interaction timing diagram of a display control method of an online document is shown. The specific implementation flow of the method is as follows:

step S81: the online document application of the target object responds to the editing operation of the target object in the target online document, updates the edited content of the target object in the document view display area and controls the display position of a cursor in the document view;

step S82: the online document server obtains updated content of at least one collaborative object after editing operation is carried out on a target online document through online document application, and content updating information aiming at the target online document is generated according to the content of the target online document updated by the at least one collaborative object;

step S83: the online document server sends the content updating information to an online document application of the target object;

step S84: when the online document application of the target object receives content updating information sent by an online document server, acquiring first position information of a cursor in a first document view from a typesetting engine;

step S85: the online document application of the target object sends the content updating information of the target online document to the typesetting engine, and acquires a second document view and second position information of a second position of the cursor displayed in the second document view from the typesetting engine;

step S86: the online document application of the target object adjusts the display content of the second document view according to the first position information and the second position information, and adjusts the display position of the cursor to the first position;
