jQuery 链式实现原理

    var aQuery = function(selector){
        return (new aQuery.prototype.init(selector));
    }
    aQuery.prototype ={
        init:function(selector){
            this.selector = selector;
            return this;
        },
        name:function(){
            return "aQuery's name"
        },
        age:10
    } 
    aQuery.prototype.init.prototype = aQuery.prototype;
    var m1 = aQuery("mery");
    var m2 = aQuery("melin");

    console.log(m1);
    console.log(m1.age);
    console.log(m1.name);
    console.log(m2);
    console.log(m2.age);
    console.log(m2.name);
