Description

The present invention claims the priority of the Chinese patent application filed on August 14, 2012 by the Chinese Patent Office, the application number is 201210289330.8, and the invention name is "page display typesetting method and device", the entire contents thereof The invention is incorporated by reference. TECHNICAL FIELD The present invention relates to the field of communications, and in particular to a method and apparatus for typesetting a page display. Background technique

Currently, most browsers in the related art use a computer-based scripting language such as JS (JavaScript) to modify the display effect of a web page by integrating a web application (Web App) framework, for example: a forum mode of uc browsing, which is usually The approach taken is to generate a forum mode page and hide the original web page.

However, there are certain problems with this approach. Because the original web page may run some JS code, these JS code is triggered by some events or timers, and may eventually generate some other elements on the page, which affects the display effect of the forum mode page, thus affecting the user's browsing experience. . 1 is a schematic diagram of displaying a Tianya Forum page on a mobile terminal according to the related art. As shown in Figure 1, after the forum mode page is generated in the browser and the web page of the original Tianya Forum is hidden, some JS of the original web page of the Tianya Forum will generate some new Hypertext Markup Language (HTML) elements. , for example: The navigation bar that appears at the bottom of the page. Since the JS of these elements is triggered by a timer, it may be executed after the JS we injected. At this time, although we hide other HTML elements, we can't hide the newly created HTML elements. Even if they are not newly created HTML elements, they may redisplay our hidden original page elements. Also, related attributes are pre-specified in the attribute list of these elements, and these attributes have higher priority, so they cannot be masked using Cascading Style Sheets (CSS). If you delete the JS of these elements to avoid the above situation, it may lead to negative effects such as imperfect web pages or incomplete information.

Since these elements that should be hidden appear on the browser's page, the original refreshed forum mode page adds some other interference elements, and the user's browsing webpage comfort is significantly reduced. Summary of the invention

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

2 is a flow chart of a method of typesetting a page display according to an embodiment of the present invention. As shown in Figure 2, the method can include the following steps:

Step S202: The page parser receives the text from the target page, where the text includes each node set in the target layout according to a preset layout manner;

Step S204: The page parser parses each node set in the text according to the preset layout mode, and after acquiring the text end message, invokes the first predetermined extension corresponding to the first predetermined calling interface through the first predetermined calling interface. The program re-formats each node that has been set in accordance with a preset layout, wherein the first predetermined calling interface and the first predetermined extension are configured in the browser.

The text end message is set at the end of the text loaded by the webpage.

In the related art, when the page is typed by injecting the JS code, the interference element cannot be avoided, thereby affecting the display effect of the page. Using the method shown in FIG. 2, a first predetermined calling interface is newly added to the client of the local browser, and a first predetermined extension program is configured for the first predetermined calling interface, and the first predetermined extension program determines Re-typesetting of each node. When the page parser resolves to the first predetermined calling interface, calling an extension program corresponding to the first predetermined calling interface, and re-provisioning each node that has been set according to the preset layout mode according to the display manner set by the extension program , solved the use of related technologies When injecting JS code to typeset a page, it is impossible to avoid the problem that the interference element affects the display effect of the page, thereby avoiding the occurrence of interference elements on the display page and improving the comfort of the user browsing the webpage.

In a preferred implementation, the first predetermined calling interface is a pre-written calling function, wherein the first predetermined extension is invoked by calling the function, and the first predetermined extension is used to determine the re-formatting mode of each node.

In a preferred implementation, the first predetermined calling interface may be, but not limited to, a JS interface.

In the above step S204, calling the first predetermined extension program corresponding to the first predetermined calling interface to re-type each node that has been set in the preset layout manner may include the following processing:

Step S1: determining a node to be re-formatted according to the first predetermined extension program, and hiding nodes other than the node to be re-typed among the nodes that have been typeset according to the preset typesetting manner.

Step S2: Re-type the target page.

By calling the extension, you can have the browser display only one or some of the nodes, leaving the other nodes hidden. Thus, even if there is a JS that can be triggered by a timer or other means, it cannot affect the target page that has already been generated.

It is assumed that three nodes A, B, and C have been displayed according to a preset typesetting manner. When the page parser resolves to the first predetermined calling interface, the first predetermined extension program is invoked, wherein the setting of the first predetermined extension program is Re-type the A node and the B node. At this time, the browser will re-type the A node and the B node in the target page according to the setting of the first predetermined extension, and hide the C node.

In the above step S1, the node to be re-formatted is determined according to the first predetermined extension program, and the nodes other than the node to be re-formatted among the nodes that have been typeset according to the preset layout mode may be hidden to include the following operations:

Setting a layout identifier for each node that has been set according to a preset layout manner, wherein the determined layout identifier of the node to be re-formatted is set to a first predetermined value, and the nodes that have been typeset according to the preset layout manner are excluded. The layout identifier of the node other than the node to be reformatted is set to the second predetermined value.

In an embodiment of the present invention, the layout identifiers may be set for each node that has been set according to the preset layout mode, and the layout identifiers of the respective nodes determine which nodes in each node need to be re-typed, and which nodes need to be hidden. When the layout identifier of the node is the first predetermined value (such as: true), it indicates that the node needs to be typeset; when the layout identifier of the node is the second predetermined value (such as: false), it indicates that the node needs to be hidden.

In the above step S2, re-formatting the target page may include the following operations:

Step S21: sequentially determining the typesetting identifiers of the respective nodes that have been set according to the preset typesetting manner; Step S22: Re-type the node whose layout identifier is the first predetermined value.

In another embodiment of the present invention, some judgments are inserted in the typesetting process, and it is determined whether a node needs to be typeset according to the value of the typesetting identifier of each node. The node is typeset only when the layout identifier of the node is the first predetermined value.

In addition, after the first predetermined extension program corresponding to the first predetermined calling interface is invoked to re-type each node that has been set according to the preset layout mode, the following steps may be further included in the step S204:

The page parser, upon parsing to the second predetermined invocation interface (eg, ucweb.ui. unsetRenderElements), invokes a second predetermined extension corresponding to the second predetermined invocation interface to redisplay some or all of the nodes that are already hidden within the current page.

In still another embodiment of the present invention, the second predetermined calling interface is a JS interface object, a JS interface object is added to the JS of the browser, and the second predetermined extension program is configured for the JS interface object, assuming The JS interface object is named "ucweb.ui", and the user interface (User Interface, UI for short) of the browser can be controlled through the interface, and corresponding functions and attributes are added to the JS interface object by calling the function. The implementation calls the second predetermined extension. Assuming that one of the functions is called "renderElements", you can change the layout of the browser by calling this function, and let the browser only type the node specified by the parameter. This parameter needs to include the set of node objects to be typeset (may be One, or more than one). The new JS interface can use JS code to call through layers to finally change the way the browser is typeset. This interface can be called to the Content Script of the Web App. Web App developers can use the new JS interface to use the Content Script of the Web App framework to notify each Web App of the corresponding registered JS file at the end of the text loading (DOCUMENT_END) stage. You can use these JS files to set up the typeset nodes.

3 is a flow chart of a typesetting method for page display of the preferred embodiment. As shown in FIG. 3, in the preferred embodiment, the browser's web page can be displayed, and the browser's new JS interface can be used to control the way the browser is typeset.

It should be noted that the browser kernel is responsible for loading, displaying, and executing the JS, which is the core of the browser, including the JS engine and the layout rendering engine; the JS front end refers to the JS code in the web page; the JS engine is Refers to the module in the browser related to JS execution.

The preferred embodiment can include the following processing steps:

Step S302: The browser kernel extends a JS interface object in the JS engine, and adds a JS sub-object in the JS interface object. Step S304: The browser kernel adds a function related to the UI operation in the JS sub-object, and maps the JS to the kernel through a Bindings module to complete the call to the relevant part of the kernel and the layout display, so that the JS can be passed through the JS. The function is transferred to the layout display module of the kernel;

Step S306: When the page parser resolves to the JS interface to change the layout node (ie, calls ucweb.ui.renderElements), the JS front end directly notifies the browser kernel.

Step S308: The browser kernel adds a variable m_inSingleLayout in the text (document) to determine whether the single typesetting mode has been entered (that is, the mode of only one node is typeset), wherein true means that the single typesetting mode has been entered, and false means no Enter single layout mode, the default setting is false. When the browser kernel receives the notification from the JS front end, set the document's mjnSingleLayout to true, and record the node m_singleRender that needs to be typeset (set the parameters of the JS function interface that only typeset some nodes to be saved. node).

Step S310: browser kernel render traverse the entire tree, and then to be provided for all layout objects (RenderObject) of m_allowLayout = false, wherein a new browser kernel in each switch layout _{_{_{RenderObject m_ a ll 0W Lay 0U t}}} , with In order to determine whether to allow the current node to typeset, if m_allowLayout=ture, it means that the current node needs to be typeset; if m_allowLayout=false, it means that the current node does not need to typeset.

Step S312: The browser kernel traverses the RenderObject of the node that needs to be typeset again, and sets all the child nodes of the RenderObject, all the ancestors of the RenderObject, and the m_allowLayout of the RenderObject node to true, indicating that the nodes need to be typeset.

Insert some judgments in the layout process, and judge whether a node needs to be typeset according to the value of m_ _a ll _0W Lay _0U t. When the attribute value of the node m_ _a ll _0W Lay _0U t is true, the node is typeset.

If a new node is inserted into the dom tree and a corresponding RenderObject is generated, first determine whether the node belongs to the child node and ancestor node of m-singleRender. If yes, set the attribute of the allowableLayout of the node to true. Otherwise, Set to false.

Preferably, after the first predetermined extension program corresponding to the JS interface object is invoked to re-type each node that has been set according to the preset layout manner, the following steps may be further included:

The page parser is parsing to another JS interface object, which is also configured in the browser, and configures a second predetermined extension for another JS interface object, assuming that the other JS interface object is added A function named "renderElements" can call the function to call the second predetermined extension, and the display of some typesetting nodes can be released. When all the nodes are unpacked, all other objects are no longer hidden. The web page element will redisplay all the nodes. The step is specifically that the JS front end notifies the browser kernel of the message called by the function. Find out the browser kernel RenderObject "released only set the layout nodes", and traverse the other RenderObject, confirm the presence of non-self, non ancestors, but also non-child node m_ _a ll _0W Lay _0U t attribute is true. If it exists, set the m_allowLayout property of the RenderObject of the "Unset Only Typeset Node" to false; if it does not exist, set the document's mjnSingleLayout to false. The browser kernel traverses the entire render tree and then sets the m_allowLayout of all RenderObjects to true. The browser kernel re-formats the entire page.

4 is a schematic diagram of a Tianya Forum display page after re-typing according to the present invention. As shown in Figure 4, the browser only types the specified nodes. Although the navigation bar is generated by JS in the later stage, after the first predetermined extension is called to re-format the page by setting the first predetermined calling interface, the unnecessary interference elements are no longer displayed on the current forum mode page.

In addition, according to the present invention, a WebApp search program can be implemented, and all the pictures on the current web page can be viewed on any webpage with the effect similar to the Windows Picture Viewer. In the related art, when the viewer is started, the original page is hidden, and a new element is generated to cause the element to display the charting program. However, a post-generated ad element may suddenly load up and appear above the image viewer, which can have a very bad experience. By adopting the technical solution of the present invention, the browser only types the picture viewer, thereby not only does not need to manually hide all the elements of the webpage, but also does not have the problem that the display page is obscured by the advertisement.
