    };

Answer 1

Make sure you are returning the correct content-type header from the server. You will need "content-type: 'application/json'". Also make sure that JSON is properly formatted, although usually IE is more strict than Firefox.

Answer 2

try adding "data:{}" & "contentType: "application/json; charset=utf-8"

Answer 3

These problem occured when i host the application,in Local it work in both the browser
