3ajaxdata.month=11;
4ajaxdata.meesage= "Test Information";
5 
6 $.ajax ({
7URL: "/home/getdata",
8 Data:JSON.stringify (Ajaxdata),
9Type: "POST",
TenContentType: "Application/json;charset=utf-8",//Remember to add charset=utf-8, otherwise AJAX requests may report SCRIPT7002 errors

 AAlert ("Request sent successfully!");
 -     },
 -Errorfunction(Result) {
 theAlert (result.status+ ":" +result.statustext);
 -     }
 -});
