If you are going to copy & paste code, you need to copy all the relevant code. Your code ends with "();" which is a call to a self defined function but your code does not start with the identifying the "function" object.
Where did you place this code?
You should realize that drop down and list fields may have a non-selected value of " " or a space; check boxes and radio buttons have a value of "Off" when no item in a group of buttons or a single check box has not been selected.
Your code if placed in the document action of "Will print" will only run after the User Interface (UI) Print appears. It also will stop testing fields when the first required field is encountered and not inform the user of the incomplete form fields.
The following might be the correct code or it at least has the obvious missing statements.
(function()
{
var val, bNotComplete = false;
var aFields = new Array("REQ2", "REQ3");
// console.println("Number of fields: " + aFields.length); // debugging statement;
for (var i = 0; i < aFields.length; i++) {
val = this.getField(aFields).valueAsString;
// console.println(i + " field name: " + aFields + " value = " + val + "length: " + val.length); // debugging statement;
if (!val) {
bNotComplete = true;
app.alert("Not all required fields are complete, so the form will print blank.", 3);
break;
} // val not empty
} // end for array of fields;
for (var i = 0; i < numFields; i++) {
this.getField(this.getNthFieldName(i)).display = bNotComplete ? display.noPrint : display.visible;
}
})();
I have added some commented out statements that trace the running of the code if the comment marker is removed.
