How to validate a form using Javascript this.mailDoc function

[Mervin.Rivid96]

I have a PDF form with a submit button to Outlook by running a Javascript command.

I have a few fields tagged as 'Required' and I also have a validation script which checks to see all said fields are filled in before submitting it.

Problem is, my code doesnt accept the value/digit zero and still rejects the submission.

How do I change the code to accept the zero digit and proceed to submission?

Any help is very much appreciated. Btw I got the code from the web, I'm no Java expert lol. 

var is_form_ok = true;
for (var i=0; i<this.numFields; i++) {
    var f = this.getField(this.getNthFieldName(i));
    if (f.type == "text" && f.required) {
        if (f.value == 0) {            is_form_ok = false;            i = this.numFields; // stop the loop
        }
    }
}

if (is_form_ok) {
    // all required fields contain data    app.alert("OK");
}
else {    app.alert("Please fill in all required fields");
}

Which values don't you want to accept, then? Just if the field is empty?

I don't mind any value as long as the field is not empty.

Then change:

if (f.value == 0) {

To:

if (f.valueAsString == "") {
