这篇文章主要介绍了通过window.location.search来获取页面传来的参数，经测试是OK的

<div class="jb51code">
<pre class="brush:js;">
function GetQueryString(name) {
var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)","i");
var r = window.location.search.substr(1).match(reg);
if (r!=null) return (r[2]); return null;
}

var sname = GetQueryString("name");
if(sname!=null)
{
var sname = decodeURIComponent(sname);
alert(sname);
}
