定义一个window对象 $xwoodjs并定义其子对象commonLib ，在页面中实例化路由调用params参数方法，代码详情如下:
<!doctype html>@b@<html>@b@<head>@b@ <meta charset="UTF-8" /> @b@ <script src="http://www.xwood.net/js/jquery-1.6.2.min.js" type="text/javascript" charset="utf-8"></script> @b@ <script>@b@ window.$xwoodjs = window.$xwoodjs || {}; @b@ $xwoodjs.commonLib = (function () {@b@ return{@b@ params : function(exist,nothing){@b@ if(location.search){@b@ exist(); @b@ }else{@b@ nothing();@b@ }@b@ },@b@ getURLParameter : function(name){@b@ var ret = (new RegExp("[\\?&]" + name + "=([^&#]*)")).exec(location.search);@b@ return ret ? ret[1] : "";@b@ } @b@ }@b@ })(); @b@ </script>@b@</head>@b@<body>@b@ <script>@b@ $(function(){@b@ //说明1. 页面加载完成后执行的函数@b@ $xwoodjs.commonLib.params(@b@ function(){@b@ exist_fun();@b@ },@b@ function(){@b@ nothing_fun();@b@ }@b@ ); @b@ @b@ function exist_fun(){@b@ document.writeln("params is:"); @b@ document.writeln("module =" + $xwoodjs.commonLib.getURLParameter("module")); @b@ } @b@ @b@ @b@ function nothing_fun(){@b@ document.writeln("params does not exist"); @b@ }@b@@b@ })@b@ </script> @b@</body>@b@</html>备注（location.href 与 location.search区别），如当前地址是http://www.xwood.net/zsk_search/?q=java
location.href获取的值(返回完整的 URL)：http://www.xwood.net/zsk_search/?q=java
location.search获取到的值(从当前URL的?号开始的字符串,含“?”)：?q=java
