Hi, sorry for not getting back sooner, I recently had surgery, so have been
out of commission.
The short answer is that not using a type attribute within an input element
is bad coding.
Since you are scripting someone elses page though, and only some of the edit
fields don't contain a type attribute, then you could check for the
following using the o object as mentioned before...
if o.type == "text" || o.type == "" then
; then o is an edit field
endif
hope this helps.
Bryan
