javascript on page open item

Explorer ,
Nov 22, 2017 Nov 22, 2017

Hi (Acrobat CC)
I've become stuck on an issue. Please excuse me, I'm a designer not programmer, and have struggled to find a solution.

I have created a form which contains an 'on page open' javascript to fill a field with the following:

var today = new Date();

this.getField("Today").value = "GCF-01-" + util.printd("mmddyyyy", today);

this.getField("Today").readonly = true;

this performs the task I require, but I want this field 'locked' when populated, so that when the form is opened again the original date remains rather than being updated.

Would someone be able to help please?

MTIA Steve

Replace this line:

this.getField("Today").value = "GCF-01-" + util.printd("mmddyyyy", today);

Fill the field when it is empty:

if (this.getField("Today").value == "") this.getField("Today").value = "GCF-01-" + util.printd("mmddyyyy", today);

Hi Bernd

Many thanks, do I add your code after the existing?

I tried yours alone and nothing appeared.

thanks, that's my ignorance.

When I started to look at the two pieces of code I could see that might be the answer, thank you for confirming!
