[javascript] Disable submit button on form submit

Want to submit value of button as well and prevent double form submit?

If you are using button of type submit and want to submit value of button as well, which will not happen if the button is disabled, you can set a form data attribute and test afterwards.

// Add class disableonsubmit to your form
    $(document).ready(function () {
        $('form.disableonsubmit').submit(function(e) {
            if ($(this).data('submitted') === true) {
                // Form is already submitted
                console.log('Form is already submitted, waiting response.');
                // Stop form from submitting again
                e.preventDefault();
            } else {
                // Set the data-submitted attribute to true for record
                $(this).data('submitted', true);
            }
        });
    });
