Add a callback function plug-in to the jQuery method.

This plug-in is used to add a callback function to the jQuery method. You can add any custom callback function to the class method or instance method without affecting the behavior of the original method. For more information, see, I hope this article will help you with the plug-in source code jquery. callback. js
