var Person=new Object();
Person["name"]="Sun";
Person["age"]=24;

var Person={

}

function parseQueryString(url)
{
var obj={};
var keyvalue=[];
var key="",value=""; 
var paraString=url.substring(url.indexOf("")+1,url.length).split("&");
for(var i in paraString)
{
keyvalue=paraString[i].split("=");
key=keyvalue[0];
value=keyvalue[1];
obj[key]=value;
