I'm trying to check field value using a button action. If it is empty, I want to add the text "N/A". If not empty, leave existing text.

Here is my code but I can't get it to work?

var f = this.getField("codeNumber").value;
event.target.value = event.target.defaultValue;
if (f.value ==""){
f.value = "N/A";
}else{
f.value = event.target.Value; }

Thanks in advance

I think I've worked it out but I would still like to know how to identify a default value.

Here's the code

var fieldName = "codeNumber"; // establish field name to process
if (getField(fieldName).value == "")
this.getField(fieldName).value = "N/A"

You can also use other properties of the "event" object like "targetName" or "target.name".

if (getField(event.targetName).value == "")
this.getField(event.targetName).value = "N/A"

If using version 4 of Acrobat:

if (getField(event.target.name).value == "")
this.getField(event.target.name).value = "N/A"

The 'event.target' is the object that triggered the action so to access the "value" property one needs to supply more information. Like:

if (event.target.value == "")
event.target.value = "N/A"
