Here is a sketch, and only a sketch from memory (and there are
alternatives):
Add a new binding to your form's submit button:
onclick="return hasEmailAddress( this.form );"
"this" is a reference to the button, form is a reference to the form in
which it is embedded
Prepare a javascript:
function hasEmailAddress( aForm ) {
return aForm.nameOfYourEMailAddressField != null;
}
"nameOfYourEMailAddressField" is whatever value you you care to assign
to the email address field in your form using the "name" tag of that
field. Since you are passing in the form, you can check as many fieilds
as you like this way.
Embed that javascript in the html of your page. You can use a
WOJavaScript component embedded in the <head> section of the page or
elsewhere. There are other ways.
Or something like the above.... YMMV,
Tom

Hello
I am a little bit lost with WO and Javascript.
I have a page with a form and some textfields. Some of them are
mandatory. When the user submti the form, it calls an action. In this
action I check if mandatory fields are not empty. If they are, I would
like to popup a small window, saying "you need to type your email" for
example.
How do I do this? I saw some JSxxxx class but I don't understand how
to use them.
Any sample code or hints to do that?
Seb
