I am trying to get this working with Bootstrap 3 and a form which is using jQuery Unobtrusive validation (in case that makes a difference). For some reason the form is performing a full page submit. I've added alerts to the script in multiple places but none are ever triggered.

Here is my code if anyone can see anything wrong?

jQuery(function ($) {
    $('form[data-async]').on('submit', function (event) {

        alert("async form");

        var $form = $(this);
        var $target = $($form.attr('data-target'));

        $.ajax({
            type: $form.attr('method'),
            url: $form.attr('action'),
            data: $form.serialize(),
            success: function (data, status) {
                alert(status);
                $target.modal('hide');
            },
            error: function (result) {
                alert(result);
            }
        });
        event.preventDefault();
    });
});

I am using jquery-1.9.0.js. I notice just before the page submits that an error gets generated in the console as follows:

"Unexpected token u" and seems to break on the following line in the jQuery source:

return window.JSON.parse( data );

The value of data at this point is true but not sure where the value has come from.

@BurnedToast is working but @riterrani can close the modal after a submit is clicked!

@BurnedToast I try your code, but there is an issue here

$(document).on('submit', 'form[data-async]', function(event) {

if I change it to

$(document).on('submit', function(event) {

Works!

@frozenade Put a div with id name of your choice and first line of the function add. In my example below I named the div id="processing"

$('#processing').html("<b>Saving...</b>");
