Javascript-获取URL请求参数

function getUrlParam()
{
    var param = [], hash;
    var url = window.location.href;//获取网页的url    var hashes = url.slice(url.indexOf('?') + 1).split('&');//将url进行参数拆分    for(var i = 0; i < hashes.length; i++)    {//循环抓取每个参数        hash = hashes[i].split('=');        param.push(hash[0]);        param[hash[0]] = hash[1];    }
return param;
}
var first = getUrlVars()["userid"];
var second = getUrlVars()["password"];
