Connect Script to UI component

[NatG]

Hi all.

Completely new to ServiceNow and Scripting.

The task is to get data from an external API and show the result.  I found this example, but not sure how to attach that onChange script.  I assume those 2 select fields has to be done in UI Builder. Managed somehow (not sure if correct or not) to set the Field select to display "common" and "official" values. Then stuck... : (

Please, help.

Thank you in advance.

Hi Brad, 

Appreciate your reply. 

I have managed to make some progress.  Figure out how to create Catalog Item not via App Studio. Also learnt how to add Catalog Client Script to a value.  Did that.  Now the selection list seems to be eager to be populated, but not yet. Please, see screenshots attached.  I feel i am getting closer....  with your help : )

It looks like maybe you need to inspect what the JSON response actually looks like. Is it an array of strings or array of objects? I think the addOption method is expecting two strings for the label and value. You might do some logging within the for loop to check that out.
