Prevent multiple POST in asp.net mvc application

Question

How do I prevent the user from posting the same data to the action multiple times if they keep clicking the submit button?

I know in php, there is a way to prevent this multiple submission, but I do not see any for asp.net mvc. Is there any?

Answer 1

You could disable the submit button using javascript. Example with jQuery:

$(function() {
    $('form').submit(function() {
        $('#idofsubmitbutton').attr('disabled', 'disabled');
    });
});

Note however that this might not be 100% reliable as for example the user could have javascript disabled or even worse: he could have malicious intents and automate HTTP POST requests.
