Combine 3 text fields into one, but omit a field if blank

Hi,

I'm trying to combine the text values from three separate text fields (LastName, FirstName, MiddleInitial) into another text field (FullName), but I want to omit the MiddleInitial field if it is blank.  I tried a few variations of the following javascript in the FullName field, but I can't get it to work:

 

{

var firstName = this.getField("FirstName").valueAsString;
var middleInitial = this.getField("MiddleInitial").valueAsString;
var lastName = this.getField("LastName").valueAsString;

 

if (middleInitial !="") {event.value = firstName + " " + lastName}
else {event.value = firstName + " " + middleInitial + " " + lastName};

}

 

Any help is much appreciated!

    Remove the surrounding braces too:

     

    var firstName = this.getField("FirstName").valueAsString;
    var middleInitial = this.getField("MiddleInitial").valueAsString;
    var lastName = this.getField("LastName").valueAsString;

    if (middleInitial == "") {event.value = firstName + " " + lastName}
    else {event.value = firstName + " " + middleInitial + " " + lastName};

    We need to know in which field this script is placed and what action triggers it.

    I just got it to work!  I should just say that I've been creating fillable PDF forms for years, but I am obviously a total rookie when it comes to javascript.  I'm trying to learn, so I really appreciate the help!

        I copied the script and pasted it in my FullName field, but it still isn't working. 😞

        You need to be more specific than that. Does it produce an output at all, but is it wrong? If so, in what way is it wrong? If there's no output at all, are there any error messages in the JS Console when you use it?

        Without these basic details we can't help you.
