Listening to click events on the submit button doesn’t work for certain cases – at least not to my knowledge. I, for example, usually don’t click the submit button but hit return instead. As far as I know, that doesn’t trigger a click event on the submit button.

jQuery.live(’submit’) will probably work on IE in a future version of jQuery.

There are other solutions to workaround that problem. One for instance (something I’ve done in one of my recent projects) is to observe clicks on submit buttons and simply send an AJAX request based on the form that the submit button belongs to.

It could be something like:

$('input[type=submit]').live('click', function() {
  var form = $(this).parents('form');
  if (form.attr('data-remote') != 'true') return; 
  $.ajax({ url : form.attr('action'), type : form.attr('method') });
  return false;
});

You could obviously use different type of elements which would send our remote forms.

I’ve written a blog post on how to achieve this, using CSS classes to do that. So you can keep the standards. Here is the post (http://www.notgeeklycorrect.com/english/2009/05/18/beginners-guide-to-jquery-ruby-on-rails/).

Regarding the HTML5, I thing it;s a really good choice to go ahead on HTML5, a bit worried about performances and users on IE …

I tried this code with jQuery 1.3.2 and it does work with submit event.

update: live with submit works on Firefox, Safari and Opera but not on IE.

jQuery.live() doesn’t support submit event at this moment. You need to use the LiveQuery plugin at this moment (http://plugins.jquery.com/project/livequery/)
