Common plug-ins in JQ and common plug-ins in JQ

Plug-in overview: The plug-in is based on jQuery's core code and compiled into a composite and standardized application. That is to say, the plug-in is also jQuery code, which can be embedded by introducing js files.

There are many types of plug-ins, which can be roughly divided: UI class, form and verification class, input class, special effect class, Ajax class, slide class, graphic image class, navigation class, integrated tool class, animation class, etc.

How can I reference a plug-in?

Some steps are required to introduce the plug-in:

1. The jquery. js file must be introduced before all plug-ins;

2. Introduce the plug-in;

3. Introduce the plug-in perimeter, such as skin and Chinese package.
