function init()

var urlarg = new getarg();
var name = urlarg.name;
var age = urlarg.age;
}

//该方法返回url后面的参数
    function getarg()
     {
var url = unescape(window.location.href);
   var allargs = url.split("?")[1];
   var args = allargs.split("&");
   for(var i=0; i<args.length; i++)
   {
    var arg = args[i].split("=");
    eval('this.'+arg[0]+'="'+arg[1]+'";');
   }
