Using user entered form field data to code a hyperlink

I figured this out:

I am simply creating a PDF flyer template with customizable contact and sales rep information. The rep has a unique URL that they will type in to the form, along with their name, title and contact. There is a graphic of a button (created in the authoring too) that I placed a transparent form submit button with the following code:

var linkers = this.getField("referralLink").valueAsString; //referralLink being the field with the URL

app.launchURL (linkers, true); //opens browser window and navigates to URL on click

Elsewhere on the PDF is a SUBMIT button that flattens the form and opens a save as prompt so that the rep can save and reuse the PDF.

I've figured this out. Thanks for your responses.

Exported to what format, exactly? You can display the URL as plain-text and it might get picked up, depending on the format.
Anything else is not likely to work.

It depends. Data can be acquired from an URL with a trusted function in Acrobat Professional. This really only works from a folder level script. Can you install an Acrobat script onto all the systems where this form will be used?

The app.launchURL() function opens a web page.
