用JS获取URL参数

<script language="javascript" type="text/javascript">
//js获取url参数的function
function request(paras){
var url = location.href;  
var paraString = url.substring(url.indexOf("?")+1,url.length).split("&");  
var paraObj = {}  
for (i=0; j=paraString[i]; i++){  
paraObj[j.substring(0,j.indexOf("=")).toLowerCase()] = j.substring(j.indexOf
("=")+1,j.length);  
}  
var returnValue = paraObj[paras.toLowerCase()];  
if(typeof(returnValue)=="undefined"){  
return "";  
}else{  
return returnValue;  
}  
}
var theurl
theurl=request("url");
if (theurl!=''){
location=theurl
}
</script>
