使用伪命名空间封装保护独自创建的对象方法

var LILL ={};//创建全局(function (wd) {function $(id) {return document.getElementById(id);}function alertNodeName(id) {alert($(id).nodeName);}var name = "aaaa"; function showName()//函数{alert(name);}alert(wd);wd['test'] = {};//创建对象wd['test']['debuglog'] = alertNodeName;wd['test']['name'] = name;showName();})(LILL);之后引用写好的js文件，然后在html页面调用<script>window.onload=function () {alert("test");LILL['test']['debuglog']('AA');}</script>
