<script language="javascript" src="js/jquery-1.9.0.min.js"></script>
<script>function Request(argname)
{
var url = document.location.href;
var arrStr = url.substring(url.indexOf("?")+1).split("&");
for(var i =0;i<arrStr.length;i++)
{
var loc = arrStr[i].indexOf(argname+"=");
if(loc!=-1)
{
return arrStr[i].replace(argname+"=","").replace("?","");

return "";
}$(document).ready(function(){
var a = Request('a'); //a的指 http://www.abc.com?a=1&b=2&c=3 中的a,也可以放b或者c
