Specifically, referring to fig. 1, fig. 1 is a basic flow chart of the data modification method of the present embodiment.
As shown in fig. 1, the data modification method includes the following steps:
s1100, receiving a modification request triggered by a user and used for modifying elements in a target page, wherein the modification request comprises: element information needing to be modified in the target page;
the target page is a page displayed in the front end, for example, a browser page, a page displayed by application software, and the like, and the format of the target page may be Extensible Markup Language (XML), HyperText Markup Language (HTML).
In practical application, in the process of developing the front end, data in a page needs to be collected, and the collected data needs to be reported. Currently, the most common is the Document Object Model (DOM), which is a platform and language neutral interface that allows programs and scripts to dynamically access and update the content, structure, and style of a Document, where the DOM defines the logical structure of a page, e.g., an XML or HTML page, i.e., a DOM tree, giving a way to access and process data in the page. Wherein, the DOM tree includes: and a plurality of nodes, each node being set with an attribute and a label of each node.
In some embodiments, some pages are complex, the nodes of which further include a plurality of child nodes, and each child node further includes a plurality of child nodes.
In practical applications, as the application scene changes, the change of the page display content often occurs to modify the attribute or the label of the element in the page. Therefore, the modification request in this embodiment is a request for indicating to modify an attribute or a tag of an element in a page, where the modification request includes: modified element information is required. The element information includes various elements displayed in the target page, for example, a picture, text, audio, video, and the like. For example, if it is desired to replace some element, i.e., text, in the target page with another text, the modified request includes the replaced text.
In some embodiments, if the picture element in the target page needs to be deleted, the modification request is empty. In some embodiments, if a new element needs to be added, the modification request further includes: and adding the position information of the node where the new element is positioned and the attribute and the label of the new element.
S1200, calling a target file object model which is the same as the original file object model of the target page from the memory according to the modification request;
in this embodiment, a target file object model completely consistent with an original file object model of a target page is pre-stored in a terminal or a server, that is, nodes included in the target file object model, and attributes and labels of elements in each node are consistent with texts of corresponding text nodes. The target file object model is used for modifying the element needing to be modified in the target page, namely, after receiving a modification request, the node in the target file object model searches for the element at the node needing to be modified and updates or replaces the element.
In some embodiments, since the front-end page includes a plurality of pages, a plurality of original document object models may be preset for each page or each part of the page, for example, a title, a column, and the like, where each pre-stored original document object model has an identification code, so as to facilitate searching in the later stage of building the target document object model.
In some embodiments, when the target file object model is established in advance, the original file object model corresponding to the identification code is searched in a plurality of pre-stored original file object models according to the identification code corresponding to the target page, each node of the original file object model is traversed, and each node of the preset file object model in the memory is set according to the element, the attribute and the label of the original file object model to obtain the target file object model.
S1300, modifying in the target file object model according to the element information so as to display the modified element information in the target page.
In practical application, the element information further includes an element tag and identification information of a target node where the element tag is located, so that when the element information is modified in the target file object model, the target node having a mapping relation with the identification information can be searched for in each node of the target file object model according to the identification information, and the tag in the target node is replaced by the element tag.
According to the data modification method, when the element of the target page needs to be modified, the element is modified in the target file object model which is preset in the memory and is the same as the file object model of the target page. Therefore, the target file object model is built in the memory and is modified to change the target page element in the virtual element, the operation of the virtual element does not affect the real file object model of the target page, and after the element of the target file object model is modified, the modified element is displayed in the target page, so that the normal display of the target page is ensured.
Further, as shown in fig. 2, in an embodiment, the step S1200 includes the following steps:
s1210, extracting an identification code of the target page from the modification request, and searching an original file object model of the target page according to the identification code;
in the embodiment of the invention, a terminal or a server receives a modification request triggered by a user, wherein the modification request is used for modifying elements in a target page and comprises an identification code of the target page, and therefore, the identification code of the target page is obtained by extracting the identification code of a file object model from the modification request.
In practical applications, a plurality of pages can be entered through hyperlinks in the front-end page, the data in the plurality of pages is more, and the element relationship included in the document object model of the page is more complex, so that in order to simplify the element relationship, a plurality of original document object models can be separately set for each page or each part in the page, for example, a title, a column, and the like. In this way, an original file object model having a mapping relation with the identification code can be searched for in the plurality of original file objects according to the identification code of the target file as the original file object model of the target page.
Further, as shown in fig. 3, in an embodiment, the step S1210 includes the following steps:
s1211, searching a file object model having a mapping relation with the identification code in a preset database;
and S1212, taking the searched file object model as an original file object model of the target page.
In the embodiment of the invention, the identification code is extracted from the modification request, the corresponding file object model is searched through the identification code, and the searched original file object model serving as the target page is used as the original file object model of the target page.
S1220, traversing each node of the original file object model to obtain an element, an attribute and a label of each node;
in practical applications, the original document object model includes a plurality of nodes, each node includes an element, and because the relationships existing in the respective elements in the target page are different, for example, an XML page includes a plurality of parallel headers, and each header further includes a plurality of subtitles, the respective nodes in the original document object model have a parallel or an inclusion relationship.
For example, the total nodes in the original object model are document nodes: document, which contains a first node < book >, which contains a plurality of second nodes < head >, < body >, < author >, < year >, and < price >, wherein the second node < head > contains a third node < title >, and the second node < body > contains two third nodes < h1> and < p >.
In the present embodiment, the element, attribute and label of each node in the original file object model are traversed, for example, for the first node < book >, the attribute "category" is extracted from it, and the label is the content in the bracket "< >".
And S1230, setting each node of a preset file object model in the memory according to the elements, attributes and labels of the original file object model to obtain a target file object model.
Through the embodiments, in practical applications, the elements in the target page have a multi-level relationship, that is, the original file object model includes multi-level nodes nested layer by layer, for example, the original file object model includes a plurality of first-level nodes, each first-level node includes a plurality of second-level nodes, each second-level node includes a plurality of third-level nodes, and so on. Therefore, in view of this, an embodiment of the present invention provides a method for creating a target file object model according to an original file object model, as shown in fig. 4, fig. 4 is a basic flowchart of the method for creating a target file object model according to an original file object model according to an embodiment of the present invention.
Specifically, as shown in fig. 4, step S1230 includes the steps of:
s12311, extracting attributes and labels of the primary nodes from the original file object model;
in the embodiment of the invention, the nodes are divided into a plurality of levels according to the hierarchy, wherein the level one node is a parallel total node, and the level one node can be a plurality of nodes. For example, the total node in the original object model is a root element node < book >, the primary node < book > is included below the total node, the attribute is "category", and the label is "book", in this embodiment, the terminal or the server extracts the label "book" and the attribute "category" of the node.
S12312, setting the attributes and the labels in the primary nodes of the preset file object model according to the attributes and the positions of the primary nodes.
And the terminal or the server creates a primary node in a preset file object model according to the number and the position of the primary node, and sets the created primary node according to the label and the attribute of the original file object model.
In practical applications, when a document element is included in the target page, the node in the original document object model also corresponds to the existing document node, for example, the text of the document node corresponding to the secondary node < title > is "(title)". In some embodiments, the level one node comprises: secondary nodes, wherein each secondary node further comprises a text node. In this embodiment, an embodiment of the present invention provides another method for creating an object model of a target file according to an object model of an original file, as shown in fig. 5, fig. 5 is a basic flowchart diagram of another method for creating an object model of a target file according to an object model of an original file according to an embodiment of the present invention.
Specifically, as shown in fig. 5, step S1230 includes the steps of:
s12321, extracting attributes and labels of the secondary nodes from each primary node, and extracting texts from text nodes corresponding to the secondary nodes;
for example, in the above embodiment, the first node < book > includes a plurality of secondary nodes < title >, < author >, < year > and < price >, where the text node corresponding to the < title > node is "Harry Potter", the text node corresponding to the attribute "lang" < author > node is "J k.rowling", and includes the third node < title >, < year > node is "2005", and the text node corresponding to the < price > node is "29.99".
In the embodiment of the method, the attributes and labels of the secondary nodes included in each primary node in the original document object model are traversed, for example, for the secondary node < title >, the attribute "lang" and the label, namely the content in the bracket "< >" are extracted from the secondary node.
S12322, setting the attributes and the labels in the secondary nodes of the preset file object model according to the attributes and the positions of the labels of the secondary nodes, and setting texts of the extracted texts in the text nodes corresponding to the secondary nodes.

Specifically, as shown in fig. 6, step S1300 includes the steps of:
s1310, searching a target node having a mapping relation with the identification information in each node of the target file object model according to the identification information;
the identification information is used for representing the position of the target node in the target file object model. The target node is a node where element information that needs to be modified in this embodiment is located, for example, in the above embodiment, a text node corresponding to a secondary node < title > is "Harry Potter", an attribute is "lang", a modification request indicates that the attribute needs to be modified to "X", then the identification information is used to indicate the position of the node where X is located, that is, the secondary node labeled "title", and the modification type is "attribute".
It should be noted that the identification information may be represented by numbers, letters, or characters, for example, if the order of the secondary node < title > is 3, and the attribute is represented by a letter, the identification information may be 23A. Wherein 2 represents two stages.
S1320, replacing the label in the target node with an element label.
In this embodiment, if the attribute "lang" of the secondary node < title > needs to be modified to "X", X is replaced with lang.
According to the method, when the elements of the target page are modified, the modified content can be displayed on the target page only by replacing the elements to be modified with the target nodes of the target file object model, the target file object model where the target nodes are located is prestored in the memory and is modified to be changed in the virtual elements, the real file object model in the target page cannot be influenced, and the normal display of the target page can be ensured.
