PDF Field Javascript Calculation to copy data from fields

I am trying to get a field in a PDF form to equal the value of another field, but if that field is blank, then I want it to to equal the value of the next field.  

For instance, what I have (that works for the first field provided data is entered): 

event.value = this.getField("field1").valueAsString; 

I need it to get data from another field IF field1 is blank, (for instance go to field2). 

 

Any help would be greatly appreciated.

Correct answer try67
if (this.getField("field1").valueAsString!="") {
    event.value = this.getField("field1").valueAsString;
} else if (this.getField("field2").valueAsString!="") {
    event.value = this.getField("field2").valueAsString;
} else if (this.getField("field3").valueAsString!="") {
    event.value = this.getField("field3").valueAsString;
} // etc.
else event.value = "";

If you have a lot of these fields you can also do it like this:

 

 

var fields = ["field1", "field2", "field3"];
event.value = "";
for (var i=0; i<fields.length; i++) {
	if (this.getField(fields[i]).valueAsString!="") {
		event.value = this.getField(fields[i]).valueAsString;
		break;
	}	
}

Thank you very much.  This worked well, but I should have fully ellaborated my scenario.  How could I continue this - for instance...if field2 is blank, get value for field3? 

It's much appreciated!
