In the related art, when a web page is designed, a template is often unable to adapt to different service requirement scenarios and cannot satisfy diverse service requirements of users. For this reason, a custom template needs to be added during page building. However, a custom template is generally complicated and cannot render a page through a Vue front-end framework. The method for rendering a page with the use of an iframe framework has many disadvantages, such as slow loading of a web page, prone to local confusion, and poor compatibility, and is not suitable for rendering an added custom template.
In S110, the current page source data is acquired. The current page source data includes data in the multiple hyper markup language (HTML) files corresponding to the multiple modules in a to-be-displayed page respectively.
The visualized page generally consists of multiple modules. Usually, each module exhibits a function and partitions the function of the visualized page, such as a title module, a content template, and a main menu module. Each module may be built by multiple templates. The data in the multiple HTML files corresponding to the multiple modules in the to-be-displayed page is acquired from a server.
Errors may occur during the downloading and transmission of page data. To ensure the integrity and correctness of the acquired current page source data, message-digest algorithm 5 (MD5) is used to check the current page source data after the current page source data is acquired. MD5 is a widely used hash function that may be used as a unique fingerprint code for a file. The basic principle of MD5 is to generate an MD5 check code by the performance of a hash operation on the current page source data. If the MD5 check code and the MD5 code attached to the page source data are the same, it indicates that received transmission data is complete and correct. If the MD5 check code and the MD5 code attached to the transmission data are different, it is necessary to re-acquire the current page source data.
The generally acquired current page source data is the data encoded by encodeURIComponent. encodeURIComponent is used to convert all characters except letters, numbers, “(”, “)”, “.”, “!”, “˜”, “*”, “′”, “-”, and “_” into Uniform Resource Locators (URLs) in Unicode Transformation Format-8 bit (utf-8). Thus, it is also necessary to invoke decodeURIComponent function to decode the current page source data.
In S120, the custom template source data in the current page source data is identified. The custom template source data is the data in the HTML file referencing an external resource.
The current page source data includes at least custom template source data and may also include at least conventional template source data. The custom template source data is the data in the HTML file referencing the external resource. The data in the multiple HTML files corresponding to the multiple modules in the to-be-displayed page is sequentially loaded and rendered by adopting a parsing sequence from top to bottom. However, based on the principle of browser rendering, the script tag referencing the external resource cannot be loaded and rendered. For this reason, the custom template source data needs to be identified, and the script tag including an src attribute in the custom template source data needs to be processed.
The custom template source data in the current page source data is identified. The custom template source data is the data in the HTML file referencing the external resource. A template identifier (ID) may be used as the unique identifier of the template. The template ID is assigned by the server during the template manufacturing process. A file type indicates the type of the template. For example, “auto-banner” indicates a carousel template, “slide-column” indicates a sliding template, “anchor-nay” indicates an anchor navigation template, and “custom-def” indicates a custom template.
In S130, the custom template source data is added to the newly created DIV tag in the current page source data to determine the child node set corresponding to the DIV tag.
The DIV tag in the HTML file is referred to as a division tag. The DIV tag is marked as <div> in the HTML file and is a block level element used for defining the partition or section in a document. The DIV tag has purity, that is, the DIV tag does not have a default margin tag and padding tag. The margin tag indicates the distance between different elements. The padding tag indicates the distance between the content of an element and the border of the element. For this reason, the custom template source data is added to the newly created DIV tag in the current page source data, so that it is easier to control the display layout of the custom template source data.
The custom template source data is added to the newly created DIV tag in the current page source data, that is, the custom template source data is added between <div> and </div>. The child nodes of the custom template source data in the DIV tag are determined to be a child node set. The child node set represents a sequential node list. The child node set includes a text node and an element node.
In S140, the external resource referenced by a tag in the child node set is acquired, and the external resource is added to the DIV tag, so that first to-be-displayed page data is obtained.
The external resource referenced by the src attribute in the script tag in the child node set is acquired. The src attribute specifies the URL of an external script file. The external resource may be a js file, that is, a web page Java Script client script file. The external resource is added to the DIV tag to obtain the first to-be-displayed page data. If multiple external resources are included, the external resources are sequentially added to the DIV tag from top to bottom according to the positions of the external resources.
For example, the content in the script tag in the child node set may be <script src=“http://www.example.com/example s”></script> or may be <script src “/scripts/example.js”></script>. The content of example.js is added to the DIV tag to obtain the first to-be-displayed page data.
In S150, the page is rendered and displayed based on the first to-be-displayed page data.
The page is rendered and displayed on a browser based on the first to-be-displayed page data.
In the technical solutions of this embodiment, the custom template source data in the current page source data is identified. The custom template source data is added to the newly created DIV tag in the current page source data to determine the child node set corresponding to the DIV tag. The external resource referenced by the tag in the child node set is acquired, and the external resource is added to the DIV tag, so that the first to-be-displayed page data is obtained. The page is rendered and displayed based on the first to-be-displayed page data. In this manner, a custom template can be added during the design of the visualized page to satisfy diverse service requirements of users.
In S210, the current page source data is acquired. The current page source data includes data in the multiple HTML files corresponding to the multiple modules in a to-be-displayed page respectively.
In S220, a template identifier and a file type corresponding to the template identifier are read from the multiple HTML files.
The current page source data includes at least custom template source data and may also include at least conventional template source data. The custom template source data is the data in the HTML file referencing the external resource. The conventional template data may be rendered and displayed by using the conventional HTML rendering method in the related art. However, for the custom template source data referencing the external resource, since the compatibility of different browsers is different, different rendering methods need to be adopted. In this manner, the visualized page can be quickly loaded and rendered. Furthermore, the custom template source data needs to be first identified from the current page source data.
The INPUT tag of the current page source data is acquired with the use of document.createElement(‘INPUT’) function. The template identifier (ID) and the file type corresponding to the template identifier (ID) are acquired with the use of input.id and input.type respectively.
For example, the INPUT tag of the current page source data is <input id=“template 1” type=“auto-banner”>; <input id=“template2” type=“custom-def”>.
In S230, a template identifier corresponding to a file type that is a target type is determined to be a custom template identifier. The data in the HTML file corresponding to the custom template identifier is determined to be the custom template source data.
The target type is the type of the custom template. The type name is defined as custom-def. If the file type corresponding to the template identifier is custom-def, the template corresponding to the template identifier is determined to be the custom template. The type name of the custom template may be configured according to user requirements and is used to distinguish the custom template from other conventional templates, such as a sliding template and a carousel template.
In S240, it is determined whether the current browser supports invoking a method for creating a document fragment.
The compatibility mode of the browser is queried to determine whether the current browser supports invoking the method for creating a document fragment (createContextualFragment). Invoking the method for creating a document fragment is supported on the IE10+ version browser, while the method for creating a document fragment (createContextualFragment) is not supported on the IE9 version browser or the browser of the iOS9 system and below versions. If the current browser supports invoking the method for creating a document fragment, steps S250 to S255 are executed. If the current browser does not support invoking the method for creating a document fragment, steps S260 to S263 are executed.
In S250, if the current browser supports invoking the method for creating a document fragment, an element set of the custom template source data is acquired by invoking the method for creating a document fragment. The method for creating a document fragment is used for analyzing the custom template source data into a document fragment, and obtaining the element set of the custom template source data based on the document fragment.
The element set (HTMLCollection) of the custom template source data is acquired by invoking the method for creating a document fragment. The HTMLCollection includes all root node tags and root node elements of the custom template source data. The root node tags include a script tag, a LINK tag, and a DIV tag.
In S251, the element set is traversed to determine a script tag.
The HTMLCollection is traversed to determine the script tag and the element of the script tag.
In S252, the external resource referenced by the script tag is loaded.
node.onload( )method is used to load the external resource referenced by the src attribute of the script tag. The external resource is an encapsulation file in js format. js files may be interdependent. Multiple js files may be loaded in sequence when the js files are interdependent.
In this case, it is necessary to load the js files in sequence from top to bottom with the use of a queue.
In S253, a document partition is created.
The js file generally has a large amount of data. There are many problems when large files are directly uploaded in a web page. First, if an error occurs during a long time of uploading, all previous efforts are wasted. Second, the configuration of the server is complicated, and the problem of receiving an extra-large form and timeout should be considered. If a large file is divided into small fragments and loaded and then merged, once the uploading fails, only one fragment is lost, and the entire file does not need to be retransmitted. For this reason, let docF: DocumentFragment=document.createDocumentFragment ( ) function is invoked to create at least one new blank document partition, that is, DocumentFragment.
In S254, the external resource is sequentially added to the document partition.
The external resource is sequentially added to the document partition. Since document fragments exist in a memory and not in a document object model (DOM) tree, when a child element is inserted into the document partition, page backflow may not be caused, so that the performance is optimized.
In S255, the document partition is added to the current page source data to obtain second to-be-displayed page data, and the page is rendered and displayed based on the second to-be-displayed page data.
All child nodes in the document partition are added to the current page source data through appendChild to obtain the second to-be-displayed page data. Only one re-rendering operation occurs in this operation, instead of each node being inserted into the document, and thus multiple re-rendering operations can be avoided.
In S260, if the current browser does not support invoking the method for creating a document fragment, the operation in S261 of adding the custom template source data to the newly created DIV tag in the current page source data is triggered and executed.
If invoking the current browser does not support invoking the method for creating a document fragment, the element set (HTMLCollection) of the custom template source data cannot be acquired by invoking the method for creating a document fragment. For this reason, an instruction is sent to trigger and execute the operation of adding the custom template source data to the newly created DIV tag in the current page source data to acquire the child node set of the custom template source data.
In S261, the custom template source data is added to the newly created DIV tag in the current page source data to determine the child node set corresponding to the DIV tag.
Optionally, the custom template source data is added to the newly created DIV tag in the current page source data to determine the child node set corresponding to the DIV tag in the manners below.
The DIV tag is created in the current page source data.
A root tag element of the custom template source data is added to the DIV tag.
The child node set in the DIV tag is determined according to the root tag element.
A blank DIV tag is created with the use of document.createElement(“div”) function. innerHTML function is invoked to add the root tag element of the custom template source data to the blank DIV tag. The child node set (childNodes) of the root tag element of the custom template source data is determined. The child node set includes a text node and an element node.
Optionally, before the custom template source data is added to the newly created DIV tag in the current page source data, the method also includes the steps below.
A wrong single tag in the custom template source data is determined by regular matching.
The wrong single tag is modified.
If double tags such as html, head, and body are single tags in the custom template source data, loading cannot be performed. The wrong single tag in the custom template source data is determined with the use of the regular matching method singleRE.test( ) The regular expression is singleRE=/{circumflex over ( )}<(\w+)\s*V?>(?:<V\1>1)$/. The end tag corresponding to the wrong single tag is added to the element content corresponding to the wrong single tag to ensure that all tags are double tags.
In S262, the external resource referenced by the tag in the child node set is acquired, and the external resource is added to the DIV tag, so that the first to-be-displayed page data is obtained.
Optionally, the external resource referenced by the tag in the child node set is acquired, and the external resource is added to the DIV tag, so that the first to-be-displayed page data is obtained in the manners below.
The child node set is converted into a child node array. The child node array is traversed to determine the script tag. The external resource referenced by the script tag is acquired from the server. The external resource is added to the DIV tag, so that the first to-be-displayed page data is obtained.
Since the child node set (childNodes) is a node list, the traversal method cannot be used. For this reason, Array.prototypr.slice.call may be invoked to convert the child node set (childNodes) into the child node array, and then the child node array may be traversed to determine the src attribute of the script tag. For example, the traversal may be implemented with the use of for Each function. The external resource referenced by the src attribute in the script tag is acquired from the server through a get request. The external resource may be a file encapsulated as js. The external resource is added to the blank DIV tag with the use of innerHTML. If there are multiple js files, the multiple js files are sequentially added to the DIV tag from top to bottom according to the positions of the external resources to obtain the first to-be-displayed page data.
In S263, the page is rendered and displayed based on the first to-be-displayed page data.
