Accessing the FORM tag with Javascript.

Question

I ran into the following problem when writing the customization portion of a Java portlet.
I have some JavaScript that I would like to have run when the customization form is submitted (ie, when the user clicks OK or APPLY).
Normally, this is easy to do by specifying the 'onSubmit' event on the <FORM> tag. But I don't seem to have access to the FORM tag
since it's being generated on the fly by Oracle Portal.
So, how do I set up my code/portlet so that I can have some Javascript executed due to the onSubmit event?

I may not be understanding the problem correctly so you may have already tried this:
You should be able to dynamically adjust any form tag's attributes after the form's been generated, you just need to know how it's identified. If Portal isn't assigning it a consistant name you can use, you still might be able to adjust it. If you can place a piece of code "inside" the form, you could access the form tag with: "this.form.onSubmit = ..." That might be your best bet, but the "this" scope can be weird if I remember right. If you don't know that your code will always be inside the form tags, your other choice would be to write a function that will iterate over each form in the frameset and test for a input field name/value that you know is unique to your form. Then you'll be able to identify the form, and finally set the onSubmit value to whatever you want.
Here's some pseudo javascript (I'm too lazy to go grab my reference guide to refresh my memory about the actual syntax you'd use) that might get you started:
foreach form in parent.forms {
if (form.foobar.value == "myUniqueValue") {
var gotmyform = form;
I think. :) It's been a while since I've done such a thing, but that's what I remember.
I don't know squat about Portal (that's why I'm here poking at these forums), so I could be completely off base. If so, I'm sorry.
Good luck,
