I want to add some simple form validation with a javascript alert. I know how to do this with a conventional submit button, e.g.



however, the form I am editing uses the Xoops form-button object. This particular form submits to another file and simply making the fields required (true) does not seem to work.

The button code looks like this.



I am no wiser about hacking the 'form' tag either



Can anyone put me out of my misery and tell me how to trigger a JS alert for an empty field when the submit button is pressed?

try using setExtra.

i thought there was an option for each element if they are to be required or not when you enter them into the form object..

Thx for responding Bandit-X. Much appreciated.

I have discovered that the form I was working on had been given the same name as another search form in a block that was also visible on the page.

It appears that the name conflict stopped the button class validation from triggering.

I changed the names and it works now.
