(function(){/* window['hyl'] = {}   function $(){ 	alert("this is my message"); } window['hyl']['$'] = $; */ var $ = jQuery = window.jQuery = function(){    return new jQuery.fn.init();}jQuery.fn = jQuery.prototype = {    init:function(){    	alert("init");        return this;    },    size:function(){        alert("size11111");    },    jquery:"1.0.0"}jQuery.fn.init.prototype = jQuery.fn;jQuery().size();})()

　　调用部分的代码

alert($().jquery);
