How to add "nNonPrint" Javascript to PDF

[deependuajish]

I'm trying to flatten a pdf but retain the weblinks. When I searched online, this came up - 

this.flattenPages({nNonPrint: 1});

I don't know Javascript and can't figure out how to add this to the PDF. I could really use some help here!

This script cannot work in Reader. You can use it in paid-for Acrobat with the JavaScript console.

I have the paid version - Acrobat DC Pro. Do you mean the people who print it have to have the paid version as well?

You can attach it to the Mouse Up event of a button and then click that button, or you could run it from the JS Console.

See: https://acrobatusers.com/tutorials/javascript_console

Does that work even after the PDF has been flattened (printed as PDF) ?

[try67]

No, that's how you flatten it in the first place.

I don't see the connection to printing. Perhaps you can explain the problem you want to solve. Certainly anyone who runs that script needs the paid-for Acrobat. 

[deependuajish]

I have the paid version.

The reason I'm printing as PDF is to essentially flatten the PDF.

I have a fill form pdf which I will send to employees, who will fill them
up and flatten (print) the PDF so that it's no longer editable.

The PDF also has weblinks that that won't work once the PDF is flattened. I
need the JavaScript for flattening the PDF but also retain the weblinks
functionality.

You can set the form fields as read only.

[deependuajish]

I have to flatten it after the form is filled. Which means I'd have to have my employees fill in the form and then edit the PDF to read-only which isn't practical for my situation.

[try67]

It can be done with literally a single click of a button.

[deependuajish]

So you don't need a paid-version or need to edit PDF to change form to READ-ONLY?

[try67]

Nope. The free Adobe Reader can do it.

[deependuajish]

How do I do that? I can't seem to find the option for converting form field to READ-ONLY.

[try67]

It requires using a script.

[deependuajish]

It's alright. I've been messing with adding the code much to my dismay. If I really need to work it out, I'm hoping this will work - https://turbofuture.com/computers/How-to-Change-A-PDF-Form-to-Read-Only-Before-the-User-Submits

I'm guessing this is what you meant as well. Thankyou for the response

[try67]

This is all you need:

for (var i=0; i<this.numFields; i++) {
	var f = this.getField(this.getNthFieldName(i));
	if (f==null) continue;
	f.readonly = true;
}

[Bernd Alheit]

Correct.

Again the flow goes like

I create a form --> Employee fills form --> Employee flattens PDF --> Employee sends to clients
