Ajax method of calling Action method of a controller:

I need to call a action method in order to save the uploaded image file using Jquery or the Ajax method. So below is the code for it.


$.ajax({
           url: "/Image/UploadTest", // Image is the controller & UploadTest is Action Method
           type: "POST",
           data: $("#frmTest").serialize(),   // Here provide the form Id
           async: false,
           cache: false,                      // Don't keep the cache
           beforeSend: function () {  // This Executes before calling the Ajax Request
                  $("#uploadProgress").show();   // Here I am showing Uploader image
              },
           complete: function () {
                  $("#uploadProgress").html("Upload completed"); 
                // Executes on Ajax request complete
              },
          success: function (msg) {

                  if (msg == "ok")
                      $("#uploadProgress").hide();  // hiding the uploader image on successs
                  else
                      alert("Error while uploading");

              }
          });
