I haven't updated my blog for a while, so I don't know what I am busy with, and I have no progress in my study.
Learn to write the JQ plug-in on your own in this week's free time.

Previously, I used Native JS to achieve a similar drag-and-drop div effect. Now I want to transform it into a small JQ plug-in based on the original idea and use it as a small exercise for making JQ plug-ins.
