Disabling observe_form AJAX request on submit button click?


I have a form that is using observe_form to periodically check for
modifications to the form and submit an AJAX request. It works really

However, by watching Firebug output, I notice that the AJAX request
always fires when I click the submit button, and even when nothing has
changed on the form.

Is there any way to suppress the firing of this AJAX request when the
submit button on the form is clicked?


Hijacking the click handler by adding this:

:onclick => ‘this.form.submit(); return false’

to the submit_tag() call for the submit button seems to work well.


I had a similar thing with a form whithout a submit button. I wanted
to use form observer. The form only had select fields (and an
autocomplete field).

If I hit enter, the form gets submitted, even if the cursor is in the
autocomplete field. Never did quite figure it out but got round it
by using field observers instead. It seemed like the focus
iinternally in the form was in a virtual submit button. If I add a
normal text field, the problem goes away.
