This article mainly introduces the first open source component encapsulated by jquery.picsign. Friends in need can refer to it

After several days of trying and learning, I encapsulated my first js component , there are many shortcomings, please enlighten me.

Due to some business needs, I need to add some annotations to the pictures. I found some on the Internet but they couldn't meet the needs, and there were some bugs and too many pitfalls.

So I had the idea to package one myself. , learned the implementation ideas of other similar components, and the development ideas of js components, and developed the jquery.picsign component
