Wanting to auto-populate initials in a field based on the first of each word in another field.

[jesset96670236]

I am building a form. At the top of each page, I need the initials of the person listed in "Name Field" (Like John Smith) to be posted at the top of every page. To clarify not the signature type initials, just the typed "JS".

Use script as validation script of "Name Field" and replace "Signature" field names to your actual field names and add more/less fields as needed:

var str = event.value;

if(event.value == ""){
this.getField("Signature1").value = "";
this.getField("Signature2").value = "";
this.getField("Signature3").value = "";}
else{
var r = str.split(" ");
var y = r[0].substr(0, 1)+r[1].substr(0, 1);
this.getField("Signature1").value = y;
this.getField("Signature2").value = y;
this.getField("Signature3").value = y;}
