js获取url参数值:JS获取URL参数

<script language="javascript">
function getrequest() {
var url = location.search; //获取url中"?"符后的字串
var therequest = new object();
if (url.indexof("?") != -1) {
var str = url.substr(1);
strs = str.split("&");
for(var i = 0; i < strs.length; i ++) {
therequest[strs[i].split("=")[0]]=unescape(strs[i].split("=")[1]);
}
}
return therequest;
}
</script>
然后我们通过调用此函数获取对应参数值：
<script language="javascript">
var request = new object();
request = getrequest();
var 参数1,参数2,参数3,参数n;
参数1 = request['参数1'];
参数2 = request['参数2'];
参数3 = request['参数3'];
参数n = request['参数n'];
</script>
以此获取url串中所带的同名参数
二、正则分析法。function getquerystring(name) {
var reg = new regexp("(^&)" + name + "=([^&]*)(&$)","i");
var r = window.location.search.substr(1).match(reg);
if (r!=null) return unescape(r[2]); return null;
}
alert(getquerystring("参数名1"));
alert(getquerystring("参数名2"));
alert(getquerystring("参数名3"));
