how to post a formdata object into ajax post call ?

i have a formdata object how do i post it using ajax post ?  I tried it this way:


but when i run it in the browser , it will just start an infinite loop, not sure why

  2.        var formData = { name: "ravi", age: "31" }; //Array 

  4.             $.ajax({
  5.                 url: "./Index ",
  6.                 type: "POST",
  7.                 data: formData,
  8.                 success: function (data, textStatus, jqXHR) {

  10.                     $("#div3").html(data);

  12.                     //data - response from server
  13.                 },
  14.                 error: function (jqXHR, textStatus, errorThrown) {

  16.                 }
  17.             });
