Abstract

The embodiment of the invention provides a webpage rendering control method, which comprises the following steps of: creating a data container which stores data which is not rendered; obtaining the screen height of the current terminal; obtaining a DOM tree generated according to webpage content analysis; establishing a relational expression between the heights of n visible DOM elements in the DOMtree and the screen height, wherein n is an integer greater than or equal to 1; acquiring respective unrendered data for the n visible DOM elements from the data container; and putting the unrendereddata of each of the n visible DOM elements into a rendering container for rendering. According to the invention, the relational expression of the heights of the n visible DOM elements and the screenheight is established, only the n effective DOM elements are rendered when the webpage is presented, rendering of invalid DOM elements is avoided, and therefore the drawing load of a browser is reduced. The embodiment of the invention also provides a control device and a computer readable storage medium.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a control method, a control device and a computer-readable medium for rendering a webpage. Background technique [0002] At present, there are many complex business scenarios in the mobile Internet environment, often accompanied by a huge amount of data support, such as product lists, order lists, historical records, notification records and other data. When the browser application retrieves these data, the data list formed by the records that meet the conditions can reach more than 100,000. When such a data list is displayed, the load on the terminal will be increased, resulting in an increase in CPU usage and memory usage. On some low-end terminals, there may even be screen freezes and flash crashes. [0003] At present, the mainstream method of long list is to store the data segmented on the server side, and get as much as the user needs from the server. After the ...
