如何将数据从 controller 方法返回到 jquery ajax 帖子

Question

My Jquery ajax call -

         var formdata = $('#emailrequest').serializeArray();

          // Ajax call to server
          $.ajax({
              url: sitePath + 'supply-chain-pressure/ProcessEmailrequest',
              type: 'POST',
              data: formdata,
              sucess: function(data) {
                  alert(data.sucess);
              },
              error: function() {
                  alert('error');
              }
              });//End Ajax

My controller -

    public ActionResult ProcessEmailrequest()
            {

              // some code

            // retun the response 
            return Json(new {success = true});

But all is get is error in alert. Where am I going wrong? Please help. I just need to return a confimation from controller, be it any format.

Answer 1

You spelled success wrong so it will never hit. It should work with the ActionResult but a JsonResult is better.

         var formdata = $('#emailrequest').serializeArray();

      // Ajax call to server
      $.ajax({
          url: sitePath + 'supply-chain-pressure/ProcessEmailrequest',
          type: 'POST',
          data: formdata,
          success: function(data) {
              alert(data.sucess);
          },
          error: function() {
              alert('error');
          }
          });//End Ajax

Answer 2

Try to set your controller method return type to JsonResult instead of ActionResult, so:

 public JsonResult ProcessEmailrequest()
 {
     // some code

     // retun the response 
     return Json(new {success = true});
 }

If that doesn't help set your ajax error function to receive following parameters:

 error: function (xhr, ajaxOptions, thrownError) {
      ...
 }

Then debug in browser and set a break point to error function and in the xhr object (responseText property) you'll be able to see exact error.

Answer 3

you shoudn't return json like that. use [ ] instead of {}

public JsonResult ProcessEmailrequest()
 {
     // some code

     // retun the response 
     return Json(new [success = true]);
 }
