[Javascript] disabling form on submit

[Roberts, Mark (Tulsa)]

Apparently this might be hard to do as so many people seem to have a
problem with it.

My initial thought would be to change the submit/button control to
execute a JS function. The first would be to disable the button followed
by a form.submit() command.

Subject: [Javascript] disabling form on submit

Hi,

I have a little issue, I am trying to create a javascript file that I
can easily include on web pages.

My idea is to have an include that disables all the form elements on
submit of the form (to signal that it is processing, and to prevent the
user from pressing the submit button multiple times).

My problem is that   if the form elements are disabled before the
submit, then they are not sent to the action Url (expected behaviour).

If I use the onsubmit event on the form and set it to "this.submit();
doDisable(); return false;", then it works fine. But no I want to take
this a step further and avoid adding code to that event, rather have the
javascript attach that event to all forms.

And that is where the headache starts. I am not sure how to
addEventListener/attachEvent to ensure that the disabling is happing
after the submission...

Any input/tips... ?
