When you try to submit a form from Javascript, using form_remote_tag, like this:

Rails:

form_remote_tag :url => {:controller => "somecontroller", :action => "} , :html => {:id => "ajax-form-1">

If you just invoke form.submit(), like this:

var form = document.getElementById('ajax-form-1');
if(form)
   form.submit();

the form will be submitted to a new page, that’s not soo ajaxy you now think. Instead use:

var form = document.getElementById('ajax-form-1');<br />
if(form.onsubmit()){
   form.submit();
}

Now your form will be submitted on the AJAX way!
