Ajax with CSRF causing a Double Post to controller

HI,
I've run into similar issues myself in the past and the solution for me was to use  event.stopImmediatePropagation() function
Here is the link to this function: https://developer.mozilla.org/en-US/docs...ropagation

And here is an example implementation from one of my projects

PHP Code:

 $('#submitbtn').on('click', function (el) {
        var formDAta = $('#tagform').serialize();
        $.ajax({
            url: '<?= site_url('tags/saveTags/entities/' . $id) ?>',
            method: 'POST',
            data: formDAta,
            success: function (data) {
                $('.collapse').toggle('toggle');
            }
        });

        // stop from calling this multiple times
        el.stopImmediatePropagation();
        return false;
    });
