Abstract

The invention discloses a tree component rendering method and device, data processing equipment and a medium. The tree component rendering method comprises the steps of obtaining data nodes in a listform; marking index values and node relationships of the data nodes; determining a data node to be rendered; and based on the index value of the data node and the node relationship, determining a display position of a to-be-rendered data node and displaying the hierarchy of the to-be-rendered data node in an internal second label; before rendering, setting a parent label, the internal first labeland the internal second label, wherein the height of the parent label is the height of a picture visual area, the height of the internal first label is the same as that of a to-be-displayed data nodelist, the internal first label is used for supporting the tree structure and forming a scroll bar for scroll display, the internal second label is used for rendering the to-be-rendered data node. According to the invention, the tree component supporting mass data rendering can be realized.

Description

technical field [0001] The present invention relates to data processing technology, in particular to a data processing method and device, data processing equipment and media. Background technique [0002] Trees are commonly used components in front-end pages. However, general tree components can only support a small amount of data. Generally, more than 3000 data nodes will have obvious problems such as rendering delays, selection and retrieval operations, etc. It is impossible to achieve smooth rendering and operation of tens of thousands or more data nodes. [0003] For some application scenarios, such as the one-time display of the tree structure formed by tens of thousands of cameras in the security industry, high-performance tree components are required. Contents of the invention [0004] In order to solve one of the above problems, the present invention provides a tree component rendering method and device, a data processing device and a medium, so as to provide a hi...
