Its actually not as easy as just creating a client script. so the Idea that @Community Alums suggested is still worth an upvote
The script include that fetchs all the notes for the UI model does a number of GlideRecord calls to the DB and then uses the returned GR to perform checks such as matching conditions and checking which field the SHN should use.
Trying to call this UI Page without the record sys_id is going to give you severely reduced functionality such as not being able to assess conditional special handling notes
That said if you wanted to create an on change client script just for this one use case and were not worried about the conditional notes or any of the other stuff that requires GlideRecord but leave all the existing OOTB code in place you could.....
1) Create a script include that fetches special handling notes. The OOTB one is "new global.SHNProcessor()" and has loads of great tools for filtering out notes. The example below is severily reduced from OOTB but you could add more checks later I just wanted to keep this one a simple function that queries the sn_shn_notes table an returns the notes for the current account such as
getPopupAlerts: function(account) {
var notes = [];
if (!gs.nil(current_table) && !gs.nil(id)) {
var get_notes = new GlideRecord('sn_shn_notes')
get_notes.addEncodedQuery("table=Account^related_record=" + account)
get_notes.query();
while(get_notes.next()){
notes.push(get_notes.getValue('sys_id'))
}
}
return notes;
},
2) then clone the UI page special_handling_notes and replace line 22 with a call to your new script include. Notice I am passing an argument called "id" into my new function that will be "account" in your script include. Id comes from the client script
3) create a client script on your case table as follows NOTE: account in my instance is called organization
