Popup and required field

[Riccardo Apotema Plus]

Hi. I need to insert a popup message when a user not to fill out a required text field.
I don't know javascript...
Someone can help me?
Thank you

What should trigger this pop-up to appear? You have to use an event, not a non-event...

My pdf has a lot of fields, but only one must be mandatory.
If the user does not fill in this field, when saving the file, the popup must show: required field.
Thanks

OK, but be aware that won't prevent the user from saving the file.

What's the name of that field?

Ok, i doesn't matter if you can save anyway. The important thing is that you see the alert.

The field is called: Data di trasferimento

Thanks again!

OK, go to Tools - JavaScript - Set Document Actions and under the Document Will Save event add the following code:

var f = this.getField("Data di trasferimento");
if (f.valueAsString==f.defaultValue) app.alert("You need to fill in \"Data di trasferimento\"!",1);

(You can adjust the text of the message to whatever you want it to be, of course)

Sorry... it says:

SyntaxError: missing ) after argument list

2: to the line 3

Remove the space between the back-slashes and the double-quotes (") characters.
