How to setup a forms function in R12 to launch an URL

First set the Profile 'Restricted Text Input' to 'No' for your User.

Then create a form function like below:

Functional Administrator > Core Services > Function > Create (button)

Name: XX_GOOGLE
Code: XX_GOOGLE
Type: SSWA jsp function
Maintenance Mode Support : none
Context Dependance: Responsibility
(press continue button)
HTML Call: javascript:void window.open("http://www.google.com")
Leave other fields blank

Add to HR_EMPLOYEE_DIRECT_ACCESS_V4.0 menu:

500 XX Google XX_GOOGLE

This will pop up your external webpage in a new window.

The issue is that it only works from the Navigator framework page (not from within Core Forms)

Cheerssss!!!
