代码如下：

//获取地址栏参数    //url为空时为调用当前url地址     //调用方法为 var params = getPatams();    function getParams(url) {        var theRequest = new Object();        if (!url)            url = location.href;        if (url.indexOf("?") !== -1)        {            var str = url.substr(url.indexOf("?") + 1) + "&";            var strs = str.split("&");            for (var i = 0; i < strs.length - 1; i++)            {                var key = strs[i].substring(0, strs[i].indexOf("="));                var val = strs[i].substring(strs[i].indexOf("=") + 1);                theRequest[key] = val;            }        }        return theRequest;    }    var params = getPatams();    //获取地址栏上的userName    var userName =  params.userName;
