This is more of a Javascript question so please forgive.

I generate a dynamic form with php.

I need to be able to test in javascript if a certain field exists:

if (document.myform.mytextfield) {

This line will give me the javascript error "document.myform.mytextfield is undefined"

If it does exist, then it works fine.

So how do I test if a field exists without getting an error?

Thanks for any help.
