Javascript

[Christian Huml]

Hello,

i refer to the following link: JavaScript™ for Acrobat® API Reference. How do you correctly address text fields and selection fields in Javacript? Is there a short form in Javascript regarding mandatory fields?

Example code that does not work:

var empty = "";

if(this.getField("Example") == empty)
{
app.alert("Error");
}
 

This is just a test.

How should the Javascript code begin in Adobe?

Best regards

I don't see an immediate problem with your code. Of course, writing the code is only half the story; you also have to decide which event to attach it to.  What happens when you try to use it. and what does it say in the console?

Try this:

var empty = "";
if(this.getField("Example").value == empty)
{
app.alert("Error");
}
