The example in this article describes how to change the color of alternate rows in a javascript table and add mouse movement in and out and click effects. Share it with everyone for your reference. The specific analysis is as follows:

The table changes color every other row, which is also a js effect that improves user experience.

Effect implementation:

The odd and even rows of the table have different colors. This prevents users from seeing data serially.
The color changes when the mouse moves into a row, and changes back when the mouse moves out. This allows users to clearly know which line they are looking at.

Click on the table to change color. It is convenient for users to select the items they want to keep.

Description:

i%2 Each number modulo 2 has only two values: 0 and 1, so that the effect of interlaced color change can be achieved
tables_li[i].onoff = 1; In order to achieve click color change, the color will not be overwritten when the mouse moves in and out.
