Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments 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 only a part of the embodiments of the present application, and not all the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

Before the embodiments of the present application are specifically described, an application scenario of the present application is described.

In the prior art, a webpage can be divided into a static webpage and a single-page webpage according to different webpage loading processes, wherein the static webpage loading process is to directly load all contents in the webpage and is not changed after the loading is finished; the loading process of the single-page webpage is to load a webpage frame firstly and then load specific contents in the webpage.

Under a modern front-end architecture, aiming at a Single-page webpage, such as a webpage in a Single-spa micro front-end application, the inventor discovers through analysis that the webpage is not in an interactive state when a frame of the webpage is loaded, so that a user cannot interact with the webpage when looking at the frame of the webpage, and interaction delay is caused.

Specifically, referring to fig. 1, an implementation manner of loading a single-page web page is provided, referring to fig. 1, and the implementation manner includes:

1. and unloading the existing page.

When a URL (Uniform Resource Locator) is input into a page, i.e., an address of a standard Resource on the internet, the original page is first unloaded, which is to release a memory occupied by the page, otherwise, the URL occupies a memory every time the URL is requested, which may cause the browser to occupy a larger memory.

2. And (6) redirecting.

Redirection is to search the requested content from the local cache, and if the requested content exists in the local cache, the requested content is directly used, and if the requested content does not exist in the local cache, the requested content is requested to the server.

3. The application is cached.

Caching applications refer to caching web applications to enable users to access usage without intervening on the network.

4. And resolving the domain name system.

In the network, each computer corresponds to an IP address, if a user wants to access a specified resource, the corresponding server must be found first, and the domain name needs to be converted into the corresponding IP address first when the server is found, namely, the DNS is used for realizing the process.

5. The server is connected through a TCP (Transmission Control Protocol).

The TCP is a lower layer Protocol of HTTP (hypertext Transfer Protocol), a TCP connection must be established between the browser and the server before the browser sends an HTTP request to the server, that is, the HTTP is dependent on the TCP, and the TCP is used to establish a connection between the browser and the server based on the IP address of the server obtained in the step 4.

6. Sending HTTP requests and receiving HTTP responses.

Sending an HTTP request refers to the browser sending the HTTP request to the server establishing the TCP connection in the step 5; receiving the HTTP response refers to the browser receiving the resource sent by the server in response to the HTTP request.

7. Parse the Document and load DOM (Document Object Model) nodes.

And 6, the resource sent by the server responding to the HTTP request is a text, the document is analyzed, the DOM node is loaded, namely the text is converted into the DOM tree, and then the DOM node in the DOM tree is loaded.

8. The script code is executed.

In the process of loading the DOM nodes and executing the script codes, the loaded DOM nodes are continuously updated with the newly loaded DOM nodes and the executed script codes.

Wherein, the time point of the above-mentioned "loading the frame of the webpage first" corresponds to the end time point of the steps of parsing the document and loading the DOM shown in fig. 1; "loading the specific content in the web page" corresponds to the ending time point of the DOM node updating step shown in fig. 1, and can be understood as follows: the actual interactable time point is a time point at which the DOM node update is completed, i.e., the completion time point of the DOM node update shown in fig. 1. Through the implementation mode, the time point when the DOM node is updated is used as the interactive time point of the webpage, so that the actual access experience of the user is better met. For a browsed webpage, the rendering efficiency is usually affected by the content displayed on the interface in the webpage. Therefore, whether to determine the time point when the update of the DOM node is completed by monitoring the change of the content in the web page, and then determining the interactive time point of the web page becomes a feasible idea.

The monitoring of the change of the content in the web page may specifically be monitoring of a change condition of a DOM region in the web page.

Wherein the DOM mentioned in step 7 above is a platform and Language neutral interface that defines the standards for accessing HTML (Hyper Text Markup Language) and XML (EXtensible Markup Language) documents, and allows programs and scripts to dynamically access and update the content, structure, and style of the documents. Taking HTML DOM as an example, HTML DOM views an HTML document, i.e., a web page, as a tree structure, which is called DOM tree and may also be called node tree.

Referring to fig. 2, fig. 2 is a schematic diagram of an HTML DOM tree according to an embodiment of the present application, where the DOM tree is composed of nodes, and the DOM tree shown in fig. 2 may include: document nodes, root element nodes, attribute nodes and text nodes;

in the HTML document, that is, all contents in the web page may be nodes, for example, the entire web page may be document nodes, each HTML element may be an element node, an outermost element node in the entire HTML document is a root element node, a text in the HTML document may be a text node, an attribute of each node may be an attribute node, and a comment may be a comment node. Of course, this is merely an example and does not represent a limitation of the present application.

With reference to the DOM tree structure of fig. 2, a specific web interface is described as an example, and specifically, referring to fig. 3, the web interface may include a plurality of different interface regions, for example: icon areas, navigation areas, banner areas, content areas, footer areas, etc., each of which may contain a plurality of nodes, such as element nodes, attribute nodes, etc., as shown in fig. 2. In summary, these interface regions can be understood as DOM regions corresponding to the DOM tree, and therefore, by monitoring changes of different DOM regions in the web page, the time point at which the update of the DOM node is completed can be determined, and further, the interactive time point of the web page can be determined.

However, in the process of monitoring different DOM regions, the inventor finds that if all DOM regions under one webpage are monitored, the efficiency is reduced, and meanwhile, the risk of webpage performance reduction exists, so that on the basis of monitoring the change condition of the DOM regions in the webpage, the inventor introduces a monitoring mode aiming at the DOM regions with the highest weight, and on the basis of reducing the monitoring range, the interaction time point of the webpage is accurately identified, so that the efficiency is ensured, and the influence on the webpage performance is reduced.

For example, referring to fig. 4, by refreshing the page, it can be roughly found that the table in the content area is displayed in the page in the last rendering, and this block is also the largest area displayed by the page.

In summary, in order to solve the problem, the present application provides a method and an apparatus for detecting a web page interactive time point, an electronic device, and a computer-readable storage medium, which can improve monitoring efficiency and accuracy of a detected interactive time point without affecting web page performance, and ensure access experience of a user.

It should be particularly noted that the web page interactive time point detection method provided by the present application may be applied to a browser, for example, an extension program of the browser, and in a process of opening a web page by the browser, each step in the web page interactive time point detection method provided by the present application is executed by the extension program of the browser. Therefore, the method can avoid the overlarge redundancy of the main program of the webpage, reduce the development and maintenance cost of the webpage and improve the loading speed of the webpage. Of course, this is only an exemplary illustration, and only a part of steps in the method for detecting a web page interactive time point provided by the present application may be applied to an extension program of a browser, which is not specifically limited in the present application.

Referring to fig. 5, the present application provides a method for detecting an interactive time point of a web page, including:

s501: and determining the weight of each node in each area of the webpage according to the weight of the label of each node on the document object model tree of the webpage.

Optionally, in order to characterize information in the nodes, in the embodiment of the present application, each node includes at least one tag.

The label of the node comprises at least: defining a table, creating a form, and defining an unordered list, wherein a weight of the defining the table is greater than a weight of the creating the form and a weight of the defining the unordered list.

The information in the node may include a web content type, a web content format, and the like corresponding to the node. For example, the < table > tag defines an HTML table, i.e., the corresponding node includes a table, < then > defines a header, < tbody > defines a body, etc., and referring to fig. 4 as an example, the content area in fig. 4 includes a table, which corresponds to the corresponding node, i.e., the < table > tag, < then > tag, < tbody > tag, etc., described above.

During the webpage loading process, the rendering time required by the form component is usually the longest, the next time is the form component and the tree component, and the rendering time required by other components is usually smaller.

It should be noted that, in this example, since the table, the form, and the unordered list belong to element nodes that have a heavy influence on the page loading rate, in this example, weights of the above several element nodes need to be determined, but the present application embodiment does not limit the nodes that need to determine the weights, and the nodes may be flexibly set based on a specific scenario, for example, the weights are determined for one or more text nodes, attribute nodes, and comment nodes that have a heavy influence on the loading rate.

Specifically, a table tag, i.e. a < table > tag in HTML, is defined, a form tag, i.e. a < form > tag in HTML, is created, and an unordered list, i.e. an < ul > tag with a root identifier in HTML, is defined, which is not described in detail later.

Alternatively, the sum of the weights of the labels of a node may be taken as the weight of the node. For example, let w (x) denote the weight of tag x, and s (x) denote the number of tags x in a node, the weight of the node, w (node), can be expressed as:

specifically, x may be < table >, < then >, < tbody >, < th >, < td >, < form >, < label >, < input >, < ul >, < li > with root id, < ul > with child id of children, etc., where w (< table >) may be 10, w (< then >) may be 5, w (< tbody >) may be 5, w (< th >) may be 2, w (< td >) may be 2, w (< form >) may be 5, w (< label >) may be 1, w (< input >) may be 2, w (ul) with root id may be 5, w (< li >) may be 1, w (< ul) may be 2 with child id of children) may be 2. In this way, the weight size of the node can basically represent the rendering time required by the node, thereby facilitating the determination of the subsequent target node. Of course, this is merely an example and does not represent a limitation of the present application.

S502: and respectively determining the total weight of each area according to the weight of each node in each area of the webpage.

In an optional embodiment, determining the total weight of each region according to the weight of each node in each region of the web page respectively includes: and calculating the sum of the weights of all nodes in all areas of the webpage to serve as the total weight of all the areas.

For example, referring to fig. 6, there are 4 regions in the web page, which are region a, region B, region C, and region D, and according to the sum of the weights of the nodes in each region, the total weight of region a is a, the total weight of region B is B, the total weight of region C is C, and the total weight of region D is D.

In an alternative embodiment, the total weight of the corresponding region may be recorded by the root node of the region. For example, when the root node of the area a is identified as a, the root node of the area B is identified as B, the root node of the area C is identified as C, and the root node of the area D is identified as D, the total weight of each area may be recorded in the manner shown in fig. 6. Of course, this is merely an example and does not represent a limitation of the present application.

S503: and determining a target node to be monitored according to the total weight of each area.

In an alternative embodiment, the target area with the maximum total weight may be determined according to the total weight of each area, and then the target node with the maximum weight may be determined according to the weight of each node in the target area.

In yet another optional implementation manner, a target area with the maximum total weight may be determined according to the total weight of each area, and then at least one target node with a weight greater than a preset threshold may be determined according to the weight of each node in the target area. Namely, the number of the target nodes can be multiple, so that the error of the obtained webpage interactive time point can be reduced.

It should be noted that, in the foregoing embodiment, the target node is a node whose weight is the largest in the area with the largest total weight or whose weight is greater than the preset threshold, in other words, the target node is a node whose rendering time is the longest in the area with the longest rendering time in the webpage loading process, so that if it is detected that rendering of the target node is completed, that is, it is detected that updating of the target node is completed, it indicates that loading of the current webpage is completed, and the time point at which rendering of the target node is completed is the webpage interaction time point. Therefore, the obtained webpage interactive time point is more in line with the actual perception of the user, and the accuracy is higher.

S504: monitoring the target node, and taking the starting time point of the preset time period as the interactive time point of the webpage when the target node is not changed in the preset time period.

And when all the nodes in the webpage are rendered, namely all the nodes in the webpage are updated, and the webpage is represented to be loaded or rendered completely. In the rendering process of the nodes, the contents in the nodes are constantly changed, and the contents in the nodes are not changed after the rendering of the nodes is finished. In the embodiment of the application, when it is monitored that the target node is not changed any more, that is, when the target node is not changed within the preset time period, the target node is considered to be rendered completely, that is, the webpage is loaded or rendered completely, and the starting time point of the preset time period, that is, the time point at which the rendering of the target node is completed, is used as the webpage interactive time point. Therefore, the obtained webpage interactive time point is more in line with the actual perception of the user, and the accuracy is higher. And the target node is monitored instead of all nodes in the whole webpage, so that the monitoring efficiency and the accuracy of the detected interactive time point can be improved on the premise of not influencing the webpage performance, and the access experience of a user is ensured.

According to the method for detecting the webpage interactive time point, firstly, the weight of each node in each area of the webpage is determined according to the weight of the label of each node on the document object model tree of the webpage, then, the target node to be monitored is determined according to the total weight of each area, so that all nodes in the target node but not the whole webpage are monitored, the webpage interactive time point is determined, on the premise that the performance of the webpage is not influenced, the monitoring efficiency and the accuracy of the detected interactive time point are improved, the access experience of a user is guaranteed, meanwhile, the target node determined according to the total weight of each area is monitored, the detected interactive time point is in line with the actual perception of the user, and the accuracy is high.

On the basis of fig. 5, please refer to fig. 7, fig. 7 shows an implementation manner of step S504 in fig. 5, that is, step S504 monitors the target node, and when the target node is not changed in the preset time period, taking the starting time point of the preset time period as the web page interactive time point may specifically include:

s514: and creating a change observer, and injecting the change observer into the webpage, wherein the change observer is used for monitoring the target node.

S524: and when the change observer does not feed back information in the preset time period, taking the starting time point of the preset time period as the interactive time point of the webpage.

The change viewer, i.e. the Mutation Observer, is the interface that monitors the DOM changes. The DOM changes, and the Mutation Observer can be informed, and the Mutation Observer is asynchronously triggered, and after the DOM changes, the Mutation Observer cannot be triggered immediately, but only when all DOM operations are finished, so that the risk of jamming of the browser can be reduced, and the adverse effect on the main thread can be avoided.

In the webpage loading or rendering process, the change observer feeds back information for many times, when the change observer does not feed back information in a preset time period, the node does not change any more, and the initial time point of the preset time period is used as the webpage interaction time point. Therefore, the obtained webpage interactive time point is more in line with the actual perception of the user, and the accuracy is higher.

In an optional embodiment, before determining the weight of each node in each region of the web page according to the label of each node on the document object model tree of the web page, the method further includes: and configuring the weight of the label of each node in the document object model tree of the webpage in an extension program in the browser.

The webpage is usually opened in a browser, and the weight of the label of each node in the document object model tree of the webpage can be configured through an extension program of the browser, so that the weight of each node in each area of the webpage can be directly calculated according to the weight of the label of each node.

In an optional embodiment, determining the weight of each node in each region of the web page according to the label of each node on the document object model tree of the web page includes: and reading the weight of the label of each node on the document object model tree of the webpage by using an extension program in the browser, and determining the weight of each node in each area of the webpage according to the weight of each node.

Specifically, the extension program of the browser may include a mapping relationship between each tag and a weight, and the extension program of the browser determines the weight corresponding to the tag of each node on the document object model tree of the web page according to the mapping relationship, so as to obtain the weight of each node in each region of the web page.

In the embodiment of the present application, a program for determining the weight of each node in each region of a web page is previously used as an extension program of a browser, and the extension program in the browser is used to read the weight of a tag of each node on a document object model tree of the web page and determine the weight of each node in each region of the web page according to the weight of each node. The method can effectively avoid the overlarge redundancy of the main program of the webpage, reduce the development and maintenance cost of the webpage and improve the loading speed of the webpage.

In an optional embodiment, before determining the target node to be monitored according to the total weight of each area, the method further includes: acquiring a root node identifier of each area; the root node identification and the total weight for each region are stored to a common data set.

The root node identifier of each region is used for indicating the region, and the root node identifier and the total weight of each region are stored in a public data set, so that the total weight of each region can be compared conveniently in the follow-up process, and the region corresponding to each total weight can be determined.

In an optional embodiment, determining a target node to be monitored according to the total weight of each region includes: and if a plurality of regions with the maximum total weight and the same total weight exist in the public data set, taking the node with the maximum weight in the regions which are finally stored in the public data set in the plurality of regions as a target node.

Therefore, the problem that the target node cannot be determined by a plurality of areas with the maximum total weight and the same total weight in the public data set can be effectively solved.

Optionally, if multiple regions with the largest total weight and the same total weight exist in the common data set, the total weight value of the region, which is stored in the common data set last, in the multiple regions may be increased by 1, so that the region, which is stored in the common data set last, is the region with the largest total weight, and thus, the problem that the multiple regions with the largest total weight and the same total weight in the common data set cannot determine the target node may also be effectively avoided.

In an optional embodiment, the listening to the target node includes: determining a root node identifier corresponding to the maximum total weight in the public data set; and taking the node with the maximum weight in the area corresponding to the root node identification as a target node, and monitoring the target node.

Specifically, the total weights in the public data set are compared to determine the maximum total weight, then the root node identifier corresponding to the maximum total weight is determined, and the area corresponding to the maximum total weight can be determined according to the root node identifier.

In an optional embodiment, the listening to the target node includes: establishing a timer with a preset interval, and acquiring a target node at the preset interval through the timer; and monitoring the target node.

Optionally, the preset interval is 16 milliseconds, so that the target node can be refreshed in real time on the premise of not obviously increasing the calculation overhead, and the accuracy of the interactive time point of the obtained webpage is improved.
