Custom Format Script

[sylvib]

I'm completely new to this, so I apologize in advance for my lack of knowledge...

I need a student ID custom format script for a field in several of my forms to be set to enter specifically the letter P followed by 10 numbers.  The P can always be there, but I need the person that fills out the form to be able to enter exactly and only 10 numbers after the P.

Can anyone help me and tell me what I need to do, or where I can learn how to do this please?

Hi.

Select the text field, right-clic : Properties : Format : Special : Arbitrary mask

Then use this mask:

P9999999999

More info: search the word "arbitrary" in this document https://helpx.adobe.com/pdf/acrobat_reference.pdf

Which script or arbitary mask would you use to not limit amount of numbers entered?

Place this as a "custom format script" :

if(event.change.charCodeAt(0)>57|event.change.charCodeAt(0)<48)
{app.beep(); event.rc=false;}
