Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

Referring to FIG. 1 , it shows a structural diagram of a server implementing page loading in a browser according to an embodiment of the present invention. The server 100 includes: a script injection module 110 , a text extraction module 120 , a storage module 140 and a communication module 130 .

The script injection module 110 is adapted to inject a text loading script into the original page sent to the client 200 after receiving the request for loading the original page sent by the client 200 . The original page is the page browsed when initially visiting the website.

The text extracting module 120 is adapted to analyze the keywords used to represent the interrelationship between the texts of the pages from the pages currently browsed by the client 200, extract the links corresponding to the keywords, download the pages corresponding to the links from the website, and extract the downloaded links. The text in the page, and store the extracted text in the storage module 140.

The storage module 140 is adapted to store the extracted text.

The communication module 130 is adapted to receive the request sent by the client 200 to load the page corresponding to the link of the keyword, and send the text corresponding to the link stored in the storage module 140 to the client 200, so that the client 200 loads the script through the text. The body is added to the body of the currently viewed page.

In order to further save network traffic, the text extraction module 120 may perform compression processing on the extracted text, and store the generated compressed package in the storage module 140 . After receiving the request from the client 200 to load the linked page corresponding to the keyword, the communication module 130 sends the compressed package of the text corresponding to the link stored in the storage module 140 to the client 200 .

Fig. 2 shows a schematic diagram of three related webpages pre-browsed by a client according to an embodiment of the present invention. The three webpages in Figure 2 are page 1, page 2, and page 3 of an article, and the content of the text on the three pages is combined into a complete article. The part framed by the box in Figure 2 is a keyword.

Keywords are used to represent the interrelationship of text between pages, for example, keywords can be "previous page", "next page", "page X" and so on. The keywords marked in FIG. 2 are only exemplary descriptions, and the keywords in the present invention are not limited thereto.

First, the script injection module 110 injects a text loading script into the original page sent to the client 200 after receiving the request to load the original page, ie, the first page, sent by the client 200 . The client 200 can add the received text to the text of the currently browsed page through the text loading script.

For the link corresponding to the keyword "next page" in the first page currently browsed by the client 200, the text extraction module 120 downloads the page corresponding to the link from the website, and extracts the text of the page corresponding to the link, that is, the text in the second page. text. Specifically, the text extraction module 120 finds "Text" in the third <div> tag pair <divclass="w1Text">...</div> by querying the html of the second page, then determines the third < The content contained in the div> tag pair is the text, and the text is extracted.

After browsing the first page, slide down the page, the client 200 receives an instruction to load the page corresponding to the keyword "next page" in the currently browsed page, and sends a link to load the link corresponding to the keyword "next page" page requests. The communication module 130 receives the request, and sends the link "next page", that is, the second page, and the text in the corresponding page to the client 200 . The client 200 adds the text to the text of the currently browsed page through the text loading script. Moreover, after receiving the text of the second page, the client 200 automatically adds 1 to the page number in the link corresponding to the "next page", so that the "next page" corresponds to the third page. After browsing the second page, slide down, the client 200 obtains the text in the third page from the server 100, and adds the text in the third page to the text of the currently browsed page through the text loading script. The complete page after the text is added in the client 200 is shown in FIG. 3 .

Further, the text extracting module 120 extracts text from the downloaded page according to the page structure of the website to which the page belongs. Taking the three pages shown in FIG. 2 as an example, it can be seen through analysis that the html of the three pages all contain "Text", and the three pages include "previous page" or "next page". From this, it can be determined that the three pages are related and all contain text. As mentioned above, the text extraction module 120 finds "Text" in the third <div> tag pair <divclass="w1Text">...</div> by querying the html of the page, then determines the third <div > Included in the tag pair is the text, extract the text.

Further, the script injection module 110 is also suitable for injecting a memory release script into the original page sent to the client 200, so that the client 200 can determine the location of the currently browsed page after receiving the instruction to load the link corresponding to the keyword. Check whether the memory occupied exceeds the preset threshold, and if so, release the memory occupied by the previously browsed text on the page.

For example, the content in the memory release script is:

parent. removeChild(e);

e=null;

deletee

After browsing the second page, slide down the page, and the client 200 receives an instruction to load the page linked to the keyword "next page". The client 200 determines whether the memory occupied by the currently browsed page exceeds a preset threshold, and if so, releases the memory occupied by the text in the first page and/or the second page.

It can be seen from the above that by injecting the memory release script into the original page sent to the client, the problem of memory overflow caused by too many texts added has been solved, and the beneficial effect of preventing memory overflow has been achieved.

Further, the script injection module 110 is also adapted to inject the reading tag function script and/or page selection function script into the original page sent to the client 200, so that the client 200 adds the reading tag function key to the currently browsed page and/or select page function keys.

Here, by injecting the function script into the original page, a function key can be added to the page of the client 200, thereby achieving the beneficial effect of extending the function in the page.

Referring to FIG. 4 , it shows a structural diagram of a server implementing page loading in a browser according to an embodiment of the present invention. In this embodiment, the server 100 includes a page preloading module 150 in addition to a script injection module 110 , a text extraction module 120 , a storage module 140 and a communication module 130 .

The page preloading module 150 is adapted to extract the link corresponding to the non-keyword in the page currently browsed by the client 200, download the page corresponding to the link from the website, compress the downloaded page, generate a page compression package corresponding to the link, and The page compression package is stored in the storage module 140 .

The link corresponding to the non-keyword is a link other than the link corresponding to the keyword in the page;

The storage module 140 is also suitable for storing page compression packages.

The communication module 130 is further adapted to receive the request sent by the client 200 to load the link corresponding to the non-keyword in the currently browsed page, and send the page compression package corresponding to the link in the request in the storage module 140 to the client 200 .

Referring to FIG. 5 , it shows a schematic diagram of a page currently browsed by a client according to an embodiment of the present invention. The embodiment is illustrated by taking the page shown in FIG. 5 as an example.

This page contains links: "Login", "Register", "Home", "Technology", "IT", "Internet", "International", "Previous Page" and so on. Among them, "previous page" is a link corresponding to a keyword, and the rest are links corresponding to non-keywords. The page preloading module 150 extracts links corresponding to non-keywords included in the page. Since the client 200 obtains the browsed page from the server 100, the server 100 can know the currently browsed page of the client 200. The page preloading module 150 downloads pages corresponding to links corresponding to each non-keyword from each website. The page preloading module 150 compresses the downloaded page, generates a page compression package corresponding to the link, and stores the page compression package in the storage module 140 . The storage module 140 may be the internal memory of the server 100, where the page compression package corresponding to the link is stored. When a link corresponding to a non-keyword in the page is clicked, the client 200 sends a request for loading the page of the clicked link. The communication module 130 receives the request sent by the client 200 , and sends the page compression package corresponding to the link in the request to the client 200 . Thus, the client 200 obtains the page compression package corresponding to the clicked link, and displays the page on the client 200 after decompressing the compression package.

In this embodiment, the server may be a cloud server, and the cloud server uniformly downloads and saves the pages corresponding to the links in the pages browsed by each client, and compresses the pages into a compressed package. When the client actually needs to download due to reasons such as link clicks, the corresponding compressed package will be sent to the client. Thus, the compressed data package of the link corresponding to the non-keyword can be provided to the client, the speed of browsing the page of the link corresponding to the non-keyword can be improved, and the browsing speed in the client can be accelerated and the network traffic of the client can be saved. An advantageous effect of reducing the workload of the client.

Referring to FIG. 6 , it shows a structural diagram of a server implementing page loading in a browser according to an embodiment of the present invention. In this embodiment, besides the script injection module 110 , the text extraction module 120 , the storage module 140 , the communication module 130 and the page preloading module 150 , the server 100 also includes a storage update module 160 .

The storage update module 160 is adapted to use the page in the compressed page package sent to the client 200 as the page currently browsed by the client 200, and combine the links corresponding to the non-keywords contained in the currently browsed page with the stored page compressed package The corresponding link is compared, and the stored page compression package is updated according to the comparison result.

Further, the storage update module 160 deletes the page compression package corresponding to the link from the storage module 140 for the link that is not included in the currently browsed page; The compressed package does not have a link corresponding to a stored non-keyword, download the page corresponding to the link from the website, compress the downloaded page, generate a page compressed package corresponding to the link, and store the page compressed package in the storage module 140 .

Referring to FIG. 7 , it shows a page updated after a client link is clicked according to an embodiment of the present invention. Take the updated page shown in FIG. 7 after the client clicks on the link “International” in FIG. 5 as an example to make an exemplary description. This page contains links: "Login", "Register", "Home", "Technology", "IT", "Internet", "International", and links to news items, such as: "4 reasons why Baidu's stock price will rise next week Reason", "Amazon says Kindlefire is a record", etc.

The storage update module 160 compares the link contained in the page with the link corresponding to the stored page compression package. Among them, "Login", "Registration", "Homepage", "Technology", "IT", "Internet" and "International" are included in the updated page, and the page compression packages corresponding to these links have been stored, Therefore, the compressed pages corresponding to these links are still stored without change. The updated page does not include the link “previous page”, therefore, the text or the compressed text package corresponding to the “previous page” is deleted from the storage module 140 . The page compression package corresponding to the news item link contained in the updated page is not stored by the storage module 140, so download the page corresponding to the news item link from the website, compress the downloaded page, and generate the page compression package corresponding to the link , and store the compressed page package in the storage module 140.

It can be seen from the above that when the page browsed in the client changes, the page compression package corresponding to the stored link is updated, so that the useful page compression package in the stored page compression package is retained, and only the new page after the change is added. The page compression package corresponding to the link can further reduce the network traffic on the server side and the workload of the server for page compression.

FIG. 8 shows a structural diagram of a client for implementing page loading in a browser according to an embodiment of the present invention. The client 200 includes: a request sending module 210 and a page loading module 220 .

The request sending module 210 is adapted to send to the server 100 a request to load the original page after receiving the instruction to load the original web page, the original page being the page browsed when the website is initially accessed, and after receiving the loading keyword corresponding After the link instruction, a request for loading the linked page corresponding to the keyword is sent to the server 100 .

The page loading module 220 is adapted to receive the original page sent by the server 100 and injected with a text loading script, load the original page, and receive the text in the page of the link corresponding to the keyword sent by the server 100, and add the text to the text through the text loading script to the body of the currently viewed page.

Since the delivered text has been pre-extracted, the speed of browsing pages can be improved. At the same time, the delivered content is only the text content, which reduces the amount of delivered data and reduces the network traffic used by the client to browse the web.

Furthermore, memory release scripts are also injected into the original page.

The page loading module 220 is also adapted to judge whether the memory occupied by the currently browsed page exceeds a preset threshold through the memory release script after receiving the instruction to load the page corresponding to the keyword, and if so, release the memory in the page. The memory occupied by the previously browsed text.

By executing the memory release script injected into the original page, the problem of memory overflow caused by too many added texts is solved, and the beneficial effect of preventing memory overflow is achieved.

Further, the original page is also injected with a tag reading function script and/or a page selection function script.

The page loading module 220 is further adapted to add a tag reading function key and/or a page selection function key to the currently browsed page by using the tag reading function script and/or the page selection function script.

By injecting the function script into the original page, a function key can be added to the page of the client, thereby achieving the beneficial effect of extending the function of the page.

FIG. 9 shows a structural diagram of a client for implementing page loading in a browser according to an embodiment of the present invention. The client 200 includes a decompression module 230 in addition to a request sending module 210 and a page loading module 220 .

In step S1120, for the link corresponding to the keyword "next page" in the first page currently browsed by the client 200, download the page corresponding to the link from the website, and extract the text of the page corresponding to the link, that is, the second page In the text. Specifically, by querying the html of the second page, it is found that the third <div> tag pair <divclass="w1Text">...</div> has "Text", then determine the third <div> tag pair Contained in is the body, extract the body.

After browsing the first page, slide down the page, the client receives an instruction to load the page corresponding to the keyword "next page" in the currently browsed page, and sends a command to load the link corresponding to the keyword "next page" page request. In step S1130, the request is received, and the link "next page", that is, the second page, is sent to the client. The client adds the text to the body of the currently browsed page through the text loading script.

Moreover, after receiving the text of the second page, the client automatically adds 1 to the page number in the link corresponding to the "next page", so that the "next page" corresponds to the third page. After browsing page 2, slide down, and the client obtains the text in page 3, and adds the text in page 3 to the text of the currently browsed page through the text loading script. After adding the text in the client, the complete page is shown in Figure 3.

Further, in step S1120, the text is extracted from the downloaded page according to the page structure of the website to which the page belongs. Taking the three pages shown in FIG. 2 as an example, it can be seen through analysis that the html of the three pages all contain "Text", and the three pages include "previous page" or "next page". From this, it can be determined that the three pages are related and all contain text. As mentioned above, by querying the html of the page, it is found that the third <div> tag pair <divclass="w1Text">...</div> has "Text", then determine the third <div> tag pair Contains the body, extract the body.

Further, the method further includes: injecting a memory release script into the original page sent to the client, so that the client can determine whether the memory occupied by the currently browsed page exceeds the preset threshold after receiving the instruction to load the link corresponding to the keyword If it exceeds the value, the memory occupied by the previously browsed text in this page will be released.

For example, the content in the memory release script is:

parent. removeChild(e);

e=null;

deletee

After browsing the second page, slide down the page, and the client receives an instruction to load the page linked to the keyword "next page". The client judges whether the memory occupied by the currently browsed page exceeds the preset threshold, and if so, releases the memory occupied by the text in page 1 and/or page 2.

It can be seen from the above that by injecting the memory release script into the original page sent to the client, the problem of memory overflow caused by too many texts added has been solved, and the beneficial effect of preventing memory overflow has been achieved.

Further, the method also includes: injecting the reading tag function script and/or the page selection function script into the original page sent to the client, so that the client adds the reading tag function key and/or the page selection function key to the currently browsed page .

Here, by injecting the function script into the original page, a function key can be added to the page of the client, thereby achieving the beneficial effect of extending the function of the page.

Referring to FIG. 12 , it shows a flowchart of a method for processing links corresponding to non-keywords in a page according to an embodiment of the present invention. In this embodiment, in addition to steps S1110 to S1130, the method further includes the following steps.

Step S1210, extracting the link corresponding to the non-keyword in the page currently browsed by the client, and downloading the page corresponding to the link from the website. The link corresponding to the non-keyword is a link other than the link corresponding to the keyword.

Step S1220, compressing the downloaded page, generating a page compression package corresponding to the link, and storing the page compression package.

Step S1230: After receiving a request from the client to load a link not corresponding to a keyword in the currently browsed page, send the page compression package corresponding to the link in the request to the client.

The embodiment is illustrated by taking the page shown in FIG. 5 as an example.

This page contains links: "Login", "Register", "Home", "Technology", "IT", "Internet", "International", "Previous Page" and so on. Among them, "previous page" is a link corresponding to a keyword, and the rest are links corresponding to non-keywords. In step S1210, the links corresponding to the non-keywords included in the page are extracted. Since the client obtains the page browsed from the server, the server can know the page currently browsed by the client. And, the pages corresponding to the links corresponding to each non-keyword are downloaded from each website. In step S1220, the downloaded page is compressed, a page compression package corresponding to the link is generated, and the page compression package is stored. When a link corresponding to a non-keyword in the page is clicked, the client sends a request to load the page of the clicked link. In step S1230, the request sent by the client is received, and the page compression package corresponding to the link in the request is sent to the client. Thus, the client obtains the page compression package corresponding to the clicked link, and displays the page on the client 2 after decompressing the compression package.

In this embodiment, the page corresponding to the link in the pages browsed by each client is downloaded and saved in a unified manner, and the page is compressed into a compressed package. When the client actually needs to download due to reasons such as link clicks, the corresponding compressed package will be sent to the client. Thus, the compressed data package of the link corresponding to the non-keyword can be provided to the client, and the speed of browsing the page of the link corresponding to the non-keyword can be improved, and the browsing speed in the client can be accelerated and the network traffic of the client can be saved. An advantageous effect of reducing the workload of the client.

In one embodiment, the method further includes: taking the page in the compressed page package sent to the client as the page currently browsed by the client, and combining the links corresponding to the non-keywords contained in the currently browsed page with the stored page compressed package The corresponding link is compared, and the stored page compression package is updated according to the comparison result.

Further, for a link that is not included in the currently browsed page, delete the page compression package corresponding to the link;

For the non-keyword-corresponding link contained in the currently browsed page and the corresponding page compression package is not stored, download the page corresponding to the link from the website, compress the downloaded page, and generate the link corresponding to the link. The page compression package stores the page compression package.

Take the updated page shown in FIG. 7 after the client clicks on the link “International” in FIG. 5 as an example to make an exemplary description. This page contains links: "Login", "Register", "Home", "Technology", "IT", "Internet", "International", and links to news items, such as: "4 reasons why Baidu's stock price will rise next week Reason", "Amazon says Kindlefire is a record", etc.

The links contained in the page are compared with the links corresponding to the stored page package. Among them, "Login", "Registration", "Homepage", "Technology", "IT", "Internet" and "International" are included in the updated page, and the page compression packages corresponding to these links have been stored, Therefore, the compressed pages corresponding to these links are still stored without change. The updated page does not contain the link "previous page", therefore, the text or the compressed body text package corresponding to "previous page" is deleted. The page compression package corresponding to the news item link contained in the updated page is not stored, so the page corresponding to the news item link is downloaded from the website, the downloaded page is compressed, the page compression package corresponding to the link is generated, and the page compression package is stored. Page compression package.

It can be seen from the above that when the page browsed in the client changes, the page compression package corresponding to the stored link is updated, so that the useful page compression package in the stored page compression package is retained, and only the new page after the change is added. The page compression package corresponding to the link can further reduce the network traffic on the server side and the workload of the server for page compression.
