Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0023] In the embodiment of the present invention, for a web page element whose CSS is not defined by the web page, the browser directly draws a matching appearance style for the web page element by calling the rendering interface of its kernel, thereby avoiding Frequent and repeated CSS parsing occurs, which effectively reduces the browser's kernel overhead and improves the browser's kernel performance.

[0024] In the embodiment of the present invention, the browser includes but is not limited to a browser running on a computer and a browser running on a mobile terminal, and the kernel used by th...

Abstract

The invention is applicable to the technical field of browsers and provides a webpage element drawing method and device. The webpage element drawing method includes steps of judging whether or not to add appearance patterns to currently analyzed webpage elements; extracting the appearance patterns matched with the types of the webpage elements from a local database when in need of adding the appearance patterns to the currently analyzed webpage elements; extracting the appearance patterns to the currently analyzed webpage elements by rendering interfaces of browser cores. In the present invention, for undefined webpage elements of CSS by the webpages, the browsers directly draw the appearance patterns matched with the webpage elements by calling the rendering interfaces of the cores, so that frequent and repeated analysis of CSS during the webpage rendering process is avoided, core expense of the browsers is effectively reduced, and core performance of the browsers is improved.

Description

technical field [0001] The invention belongs to the technical field of browsers, in particular to a method and device for drawing web page elements. Background technique [0002] At present, mobile browsers use the cascading style sheet (Cascading Style Sheet, CSS) defined by the webpage to complete the drawing of webpage elements. For webpage elements that do not define CSS, mobile browsers usually match a CSS for the webpage element. to complete the drawing of the webpage element. [0003] However, the above method increases the parsing process of the webpage by the mobile browser: when the mobile browser parses a webpage element that does not define CSS, it needs to match a CSS for the webpage element, and then perform CSS parsing on the webpage element again. In the future, once the number of webpage elements without CSS defined in the webpage is large, the mobile browser needs to repeat the above process to parse too much CSS, thereby increasing the kernel overhead of ...
