Prevent double submission of forms in jQuery

Question

I have a form that takes a little while for the server to process. I need to ensure that the user waits and does not attempt to resubmit the form by clicking the button agai

Answer 1

Timing approach is wrong - how do you know how long the action will take on client's browser?

How to do it

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

When form is submitted it will disable all submit buttons inside.

Remember, in Firefox when you disable a button this state will be remembered when you go back in history. To prevent that you have to enable buttons on page load, for example.
