Why is this so difficult? Creating an alert to show when a caller is a member of a particular group.

[JennyBell]

I have run this scenario in the community, Google and Copilot multiple ways and there are so many different ways this can be done I'm getting confused because each one I try does not work.  Can someone provide a script to do the following:  

When a name is entered into the caller id field on the Incident form, check if the caller id is a member of a group.

Caller_ID:  Jen Nocode

Group: Pilot_Participant

If, yes Jen Nocode is a member of the Pilot Participant group = show an alert telling the call taker the user is a pilot participant

If No, no alert needed

Some solutions provided had me create a Business Rule and a Client Script, some had just a Client Script.

Thanks!

You cannot validate server-side functions directly from client script. You need to first create script include function that is client callable and create a client script to call the script include.

Below is a reference,

You can finetune for your requirements and it should work.

Script Include

var CheckmemberOf = Class.create();
CheckmemberOf.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    checkGroupMember: function() {
        var grp = this.getParameter('sysparm_grp');
        return gs.getUser().isMemberOf(grp);
    },
    type: 'CheckmemberOf'
});

Client Script

function onLoad() {
    var ga = new GlideAjax('CheckmemberOf');
    ga.addParam('sysparm_name', 'checkGroupMember');
    ga.addParam('sysparm_grp', 'group sys_id');
    ga.getXML(checkGroup);
}

function checkGroup(response) {
    var answer = response.responseXML.documentElement.getAttribute("answer");
    if (answer == 'true') {
        alert('User is a Pilot Participant');
    } 
}
