相信码友们对于$.fn.extexd();$.extend()以及$.fn.custom和$.custom都有一定的了解；我阐述一下我自己对于$.fn.custom和$.custom的理解、有理解错误或是有更好的建议直接喷我就好！

下面咱们进行简单插件的封装；

Jquery为开发插件提供了两个方法，分别是：

$.fn.INFOplug= $.INF_Oplug=function(){}

先简单的阐述下这两种方法：

这两个分别是:

$.INFplug;是为了扩展jquery本身，为类添加新的工具方法;

$.fn.INFOplug;给jquery对象添加方法。

例子：

$.fn.INFOplug=function(a,b){

alert(a+b)

};

$.INF_Oplug=function(a,b){

alert(a+b)

}

该两种方法分别：

在jquery对象上创建了一个INFOplug方法；该方法中打印a+b；

在jquery上拓展了工具INF_Oplug方法；打印如上a+b；

两者的使用方法是不同的，下面举个实例：

INFOplug方法:

$('p).INFOplug(4,5);

INF_Oplug方法：

$.INF_Oplug(4,5)

这是两者大致的意思，下面我们用这两个方法进行封装一个基于jquery的弹窗插件，代码如下:
