I had a requirement where we needed to hide a UI Action from the top form header and display it only at the bottom of the form.

UI Action:

When a UI Action is enabled as a Form button, ServiceNow automatically renders it in both the header and the bottom sections of the form.

Client Script:

function onLoad() { //Type appropriate comment here, and begin script below g_form.addInfoMessage("TEST1"); /* This line selects the UI Action button with the data-action-name value test from the form’s HTML using ServiceNow’s jQuery ($j) */ var ans = $j('[data-action-name="test"]')[0].hide(); g_form.addInfoMessage("Answer: " + ans); }

Disable Isolate Script:

Turn off script isolation (set Isolate Script = false) so the client script can interact with the form’s DOM elements.

What happens when made true?

When Isolate script = true, ServiceNow:

• Runs the script in a sandboxed scope
• Prevents access to:
  • Global objects
  • DOM
  • window
  • $j / jQuery
• Allows only safe APIs like:
  • g_form
  • g_user
  • GlideAjax

UI Action on the Target:

Result:

Happy Learning!!
