这是个最简单的：（方法调用模式）

<script src="http://cdn.bootcss.com/jquery/1.12.1/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
var WG={
    prov:11,
    city:234,
    test1:function(){
        alert(this.city);
    }
}
WG.test1();
</script>

多级类：　　2016-3-17

这是类似json串的写法。都是“名——值”的对应关系。 值可以是属性、方法，还可以是对象、数组————只要你愿意，把什么都可以塞进去

<script src="http://cdn.bootcss.com/jquery/1.12.1/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
var WG={
    city:110,
    test1:function(){
        alert(this.city);
    },
    base:{
        city:110101,
        test1:function(){
            alert(this.city);
        },
        test2:function(){
            alert(WG.city);
            alert(WG.arr[2]);
        }
    },
    arr:[555,444,333,222,111]
}
//-----------------------------
    $("#button1").click(function(){
        WG.test1();
    });
    $("#button2").click(function(){
        WG.base.test1();
    });
    $("#test2").click(function(){
        WG.base.test2();
    });

});
</script>
<input type="button" value="一级" id="button1">
<input type="button" value="二级" id="button2">
<input type="button" value="test2" id="test2">

jQuery.fn.extend(object) ; 给jQuery对象添加方法。

jQuery.fn = jQuery.prototype = { }

jQuery.extend(object); 为扩展jQuery类本身.为类添加新的方法。
