 try{

  var i;
  if(returnCitySN){
   i=returnCitySN;
   var ip = i['cip'];
  alert(ip);//返回IP
   if(ip == "XX"){
    document.write('<script type="text/javascript" src="http://xxxx/.jsp"><\/script>');
    
   }else{
    
    document.write('<script type="text/javascript" src="http://xxxx/.jsp"><\/script>');
