How to do a Jquery Callback after form submit?

I have a simple form with remote=true.

This form is actually on an HTML Dialog, which gets closed as soon as the Submit button is clicked.

Now I need to make some changes on the main HTML page after the form gets submitted successfully.

I tried this using jQuery. But this doesn’t ensure that the tasks get performed after some form of response of the form submission.

$("#myform").submit(function(event) {

// do the task here ..


How do I attach a callback, so that my code gets executed only after the form is successfully submitted? Is there any way to add some .success or .complete callback to the form?


Thank you for visiting the Q&A section on Magenaut. Please note that all the answers may not help you solve the issue immediately. So please treat them as advisements. If you found the post helpful (or not), leave a comment & I’ll get back to you as soon as possible.

Method 1

I just did this –

 $("#myform").bind('ajax:complete', function() {

         // tasks to do 


And things worked perfectly .

See this api documentation for more specific details.

Method 2

I could not get the number one upvoted solution to work reliably, but have found this works. Not sure if it’s required or not, but I do not have an action or method attribute on the tag, which ensures the POST is handled by the $.ajax function and gives you the callback option.

<form id="form">
<button type="submit"></button>

$(document).ready(function() {
  $("#form_selector").submit(function() {

     type: "POST",
      url: "form_handler.php",
      data: $(this).serialize(),
      success: function() {
        // callback code here


Method 3

You’ll have to do things manually with an AJAX call to the server. This will require you to override the form as well.

But don’t worry, it’s a piece of cake. Here’s an overview on how you’ll go about working with your form:

  • override the default submit action (thanks to the passed in event object, that has a preventDefault method)
  • grab all necessary values from the form
  • fire off an HTTP request
  • handle the response to the request

First, you’ll have to cancel the form submit action like so:

$("#myform").submit(function(event) {
    // Cancels the form's submit action.

And then, grab the value of the data. Let’s just assume you have one text box.

$("#myform").submit(function(event) {
    var val = $(this).find('input[type="text"]').val();

And then fire off a request. Let’s just assume it’s a POST request.

$("#myform").submit(function(event) {
    var val = $(this).find('input[type="text"]').val();

    // I like to use defers :)
    deferred = $.post("", { val: val });

    deferred.success(function () {
        // Do your stuff.

    deferred.error(function () {
        // Handle any errors here.

And this should about do it.

Note 2: For parsing the form’s data, it’s preferable that you use a plugin. It will make your life really easy, as well as provide a nice semantic that mimics an actual form submit action.

Note 2: You don’t have to use defers. It’s just a personal preference. You can equally do the following, and it should work, too.

$.post("", { val: val }, function () {
    // Start partying here.
}, function () {
    // Handle the bad news here.

Method 4

For MVC here was an even easier approach.
You need to use the Ajax form and set the AjaxOptions

@using (Ajax.BeginForm("UploadTrainingMedia", "CreateTest", new AjaxOptions() { HttpMethod = "POST", OnComplete = "displayUploadMediaMsg" }, new { enctype = "multipart/form-data", id = "frmUploadTrainingMedia" }))
  ... html for form

here is the submission code, this is in the document ready section and ties the onclick event of the button to to submit the form


here is the callback referenced in the AjaxOptions

function displayUploadMediaMsg(d){
    var rslt = $.parseJSON(d.responseText);
    if (rslt.statusCode == 200){
        $().toastmessage("showSuccessToast", rslt.status);
        $().toastmessage("showErrorToast", rslt.status);

in the controller method for MVC it looks like this

public JsonResult UploadTrainingMedia(IEnumerable<HttpPostedFileBase> files)
    if (files != null)
        foreach (var file in files)
            // there is only one file  ... do something with it
        return Json(new
            statusCode = 200,
            status = "File uploaded",
            file = "",
        }, "text/html");
        return Json(new
            statusCode = 400,
            status = "Unable to upload file",
            file = "",
        }, "text/html");

Method 5

I do not believe there is a callback-function like the one you describe.

What is normal here is to do the alterations using some server-side language, like PHP.

In PHP you could for instance fetch a hidden field from your form and do some changes if it is present.


  $someHiddenVar = $_POST["hidden_field"];
    if (!empty($someHiddenVar)) {
        // do something 

One way to go about it in Jquery is to use Ajax. You could listen to submit, return false to cancel its default behaviour and use instead. has a success-callback.

$.post("test.php", $("#testform").serialize(), function(data) {

Method 6

The form’s “on submit” handlers are called before the form is submitted. I don’t know if there is a handler to be called after the form is submited. In the traditional non-Javascript sense the form submission will reload the page.

Method 7

$("#formid").ajaxForm({ success: function(){ //to do after submit } });
