利用javascript接收参数传递

<script language="javascript">

var tmpArr,QueryString;
var URL = document.location.toString();
if(URL.lastIndexOf("?")!=-1){
QueryString= URL.substring(URL.lastIndexOf("?")+1,URL.length);
tmpArr=QueryString.split("&");
alert(tmpArr.length)
        for (i=0;i<tmpArr.length;i++)
        {        try{
           var ID= eval (tmpArr[i]);
    
     alert("ID"+ID);
      }
                catch (e){
                        var re = new RegExp("(.*)=(.*)","ig");
                        re.exec(tmpArr[i]);
                        try{eval (RegExp.$1+"="+"\""+RegExp.$2+"\"");}
                        catch(e){}
                }
        }
}
else
{
QueryString="";
}
</script>
