Empty Message through Script

[Former Community Member]

Empty Message can be written manually if the fields are set required or recommended.

Is it possible to add empty message through Script? If so How can I get this?

you could use isNull. So in formcalc for example you could put in the exit event:

if ($.isNull) then

xfa.host.messageBox("This field cannot be left blank")

endif
