At onSubmit Event() how do I find the element that made the request

[swissneil]

I would like to reference the "request" object to see which form element was actually
clicked to fire the submit event.
Is this possible ?

My functionality work as follows.I've got and <input type=&quot;image&quot; name=value1.....>
I want the submit event triggered by a click
on this image to return me true or false depending on the dropdown selection.
At the moment I am able to see which element was selected in the dropdown
but I also need to know which form element was used for submitting.I only want this
functionality for my <input type=&quot;image&quot; value1.....> and not for the other buttons or text fields on my form.

Appreciate some input.
Thanx.
