The example in this article describes the method of using JS to move LI rows of data up and down by clicking. Share it with everyone for your reference. The details are as follows:

Here is a demonstration of the JavaScript sorting function. Click the button to move up and down the data. There are two sets of test effects. The upper group uses arrow icon control, which is more beautiful. The lower group uses text directly, according to your needs. Make your own choice. myList is the id value of ul, m is 0 to display text, m is 1 to display pictures, mO and mT are text or picture content.

The demonstration effect is as shown below:

The specific code is as follows:
