Re: disable submit button when pressed

[ausias vives <au...@yahoo.co.uk>]

Hi,

The trick in this case is that you always call the
listener form method, cause I'm using a unique
submit/image per form, and I can assure you that it
works.

If you have more than one submit/image per form you
can use a hidden javascript parameter that will be
used as a discriminator by you form listener to
discover which submit/image was pressed, it works well
for me too. Maybe it's not the better or cleaner
solution but has solved my big problems with
re-submitting forms.

Hope this clarifies...
