Preventing action in web application from being called twice (ASP.NET MVC)

What is the best way to make sure an ASP.NET MVC action is not called twice (i.e. if the user clicks on a button twice in quick succession)? On most of our screens, it's not a big deal if it happens ... but on a few it causes havoc (like paying people multiple times instead of just once).

There was a recent thread about this (with Darin actually).

A combination of doing as he mentioned and implementing a Post-Redirect-Get strategy covers most holes.

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

$(function() {
    $('form').submit(function() {
        $(':submit, :image', this).attr('disabled', 'disabled');
    });
});
