Abstract
A method for dynamically adapting different IE kernels by a browser client. Each IE kernel rendering process of the browser may dynamically specify different IE kernel versions for different web site URLs through a white list. And before navigation, the rendering process judges whether the current URL needs to use the specified IE kernel version by comparing the white list. When the browser process downloads the server-side webpage data, if the current webpage needs to specify the IE kernel version, adding the Meta-information tag Meta corresponding to the IE kernel version in the document header tag head of the current webpage data. After downloading the network data, the IE kernel rendering process selects a corresponding compatible kernel version for rendering according to the first Meta-information tag Meta in the page, so that the aim of flexibly designating different IE kernel versions is fulfilled. The method and the device are used for the browser client to dynamically adapt to different IE kernels.
Description
The technical field is as follows:
the invention relates to a method for dynamically adapting different IE kernels by a browser client.
Background art:
the browser kernel is responsible for interpreting the web page syntax (e.g., hypertext markup language HTML, running script JavaScript) and rendering the web page. The so-called browser kernel is an engine that downloads, parses, executes, and renders a page, and determines how the browser displays the content of the web page and the format information of the page.
At present, due to the complex structure of the internet in China, a large number of websites or services developed by adopting different specifications based on different versions of browsers IE exist in a client, and the client can only normally operate under a browser adopting a specific browser IE kernel. Therefore, when a user uses the browser client, various flexible kernel switching requirements need to be met according to different pages.
In summary, one technical problem to be solved urgently by those skilled in the art is how to solve the problems of compatibility and adaptability of a browser client in an IE kernel of a browser, so that a user can obtain better webpage browsing experience.
The invention content is as follows:
the invention aims to provide a method for dynamically adapting different IE kernels by a browser client.
The above purpose is realized by the following technical scheme:
a method for dynamically adapting different IE kernels at a browser client side is provided, wherein each IE kernel rendering process of a browser can dynamically assign different IE kernel versions for different URL through a white list. And before navigation, the rendering process judges whether the current URL needs to use the specified IE kernel version by comparing the white list. When the browser process downloads the server-side webpage data, if the current webpage needs to specify the IE kernel version, adding the Meta-information tag Meta corresponding to the IE kernel version in the document header tag head of the current webpage data. After downloading the network data, the IE kernel rendering process selects a corresponding compatible kernel version for rendering according to the first Meta-information tag Meta in the page, so that the aim of flexibly designating different IE kernel versions is fulfilled.
The method for dynamically adapting to different IE kernels at the browser client side judges and acquires the network download data of the current URL through intercepting the calling process of the Internet service wining.
According to the method for dynamically adapting different IE kernels by the browser client, if a target webpage needs to use the browser IE8 kernel, a Meta-information tag < Meta http-equiv = 'X-UA-Compatible' content = 'IE = 8' is added after a document header tag head of downloaded webpage data, and a current rendering process is informed to forcibly use the IE8 kernel for rendering for the current webpage.
Has the advantages that:
1. the invention achieves the purpose of flexibly appointing the page version by intercepting and modifying the server-side webpage data downloaded by the browser process and adding the Meta-information tag Meta corresponding to the browsing IE kernel version in the document head tag head of the existing webpage data.
The method and the device can accurately control the same rendering process to adapt to different IE kernels, and improve the flexibility of webpage adaptation.
Description of the drawings:
FIG. 1 is a flow chart of the product.
The specific implementation mode is as follows:
the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the present invention.
Example 1:
a method for dynamically adapting different IE kernels of a browser client not only adopts a scheme of modifying the version of the positive kernel of the browser by using a registry, but also can flexibly assign multiple browser IE kernel versions in each IE kernel rendering process of the browser, and only needs to assign the positive kernel version to a website URL and add the positive kernel version to a white list. And before navigation, the rendering process judges whether the current URL needs to use the rendered appointed IE kernel or not by comparing the white list.
When the browser process downloads the server-side web page data, if the current web page needs to specify the browser IE kernel version, the Meta-information tag Meta corresponding to the browser IE version is added to the document header tag head of the current web page data, so that the aim of forcibly specifying the page IE kernel version is fulfilled.
After the browser IE kernel rendering process finishes downloading the network data, different compatible kernel versions can be selected according to a first Meta-information tag Meta tag in a page. Therefore, the browser rendering process is controlled to flexibly render according to the appointed IE kernel version.
Example 2:
the method for dynamically adapting to different IE kernels of the browser client described in embodiment 1 determines and acquires network download data of a current URL by intercepting a call process of internet service winet.
Example 3:
in the method for dynamically adapting to different IE kernels by a browser client described in embodiment 1, if a target web page needs to use a browser IE8 kernel, a meta-information tag < Metahttp-equiv = "X-UA-Compatible" content = "IE =8" is added after a document header tag head of downloaded web page data, and a current rendering process is notified to forcibly use an IE8 kernel for rendering a current web page.
Example 4:
the method for dynamically adapting to different IE kernels by a browser client described in embodiment 1 includes a website URL matching step of obtaining a website URL currently accessed by a browser process, performing accurate comparison or fuzzy matching with a stored white list, and determining whether the current website URL needs to designate a kernel.
And if the kernel needs to be specified, acquiring the corresponding version number character string stored in the white list.
And thirdly, returning the corresponding Meta information tag Meta character string for use according to the acquired version number information.
Example 5:
the method for dynamically adapting to different IE kernels in embodiment 1 inserts Meta information tag Meta information,
intercepting data of a document Type Content-Type returned by a webpage server as 'text/html' data when specified kernel information needs to be inserted.
And analyzing whether the intercepted webpage data contains a document head label head webpage element.
If the current data contains a head element of a document head label head, returning the obtained Meta information label Meta character string before inserting the head element of the document head label head.
Example 6:
in the method for dynamically adapting to different IE kernels by a browser client described in embodiment 1, the browser compares URL information of a URL (uniform resource locator) submitted by a user according to a stored white list, and determines whether a current page needs to be switched to a dedicated IE kernel version of the browser, and if the comparison is successful, it indicates that the current page needs to be adapted to the dedicated IE kernel version, and a rendering process injects different Meta information tag Meta elements into the current page, thereby achieving the purpose of setting different kernels.
