Create a script include and a client script to show "caller" email and phone number as a field msg

[jordanbenbelaid]

Trying to create a script include and a client script to show the "caller" info (email and phone number) as a field message under caller, that changes dynamically when the "caller is changed in an incident.

I have tried about 15 different script includes and client scripts, here are the latest that I have done

SCRIPT INCLUDE:

// CallerInfoScriptInclude script include

var CallerInfoScriptInclude = Class.create();

CallerInfoScriptInclude.prototype = {

  initialize: function() {},

  getCallerInformation: function(callerID) {

    var caller = new GlideRecord('sys_user');

    if (caller.get(callerID)) {

      var email = caller.email.getDisplayValue();

      var phoneNumber = caller.phone.getDisplayValue();

      return "Email: " + email + "\nPhone Number: " + phoneNumber;

    } else {

      gs.error("CallerInfoScriptInclude - Unable to find user with ID: " + callerID);

      return "Error retrieving caller information.";

    }

  },

  type: 'CallerInfoScriptInclude'

};

CLIENT SCRIPT:

function onChange(control, oldValue, newValue, isLoading) {

  if (isLoading || newValue === '') {

    return;

  }

  // Replace 'caller_id' with the actual name of the caller reference field on your Incident table

  var callerField = g_form.getControl('caller_id');

  // Use GlideAjax to call the server-side script include

  var ga = new GlideAjax('CallerInfoScriptInclude');

  ga.addParam('sysparm_name', 'getCallerInformation');

  ga.addParam('sysparm_user_id', newValue);

  ga.getXMLAnswer(function(response) {

    if (response) {

      // Remove existing messages before adding a new one

      g_form.clearMessages();

      // Display the information as a message in the caller field

      g_form.showFieldMsg('caller_id', response);

    }

  });

}

Any help would be appreciated, at the moment nothing comes up but before with a slightly different script I was getting a TypeError

So we good now? you can take it form here?

[jordanbenbelaid]

Still not sure why the data is not showing, as there message is being shown in a blue info box rather than the red error message box

[Anurag Tripathi]

Add logs and alerts to see how it is being processed

Will do, thanks

Taking a quick stab at this.

Following the recommended change, I just noticed the following lines

getCallerInformation: function(callerID) {
    var caller = new GlideRecord('sys_user');
    if (caller.get(callerID)) {

There is no parameter to pass so...

getCallerInformation: function() {
    var callerID = this.getParameter('sysparm_user_id');
    var caller = new GlideRecord('sys_user');
    if (caller.get(callerID)) {

EDIT: Just wanted to add, that from a programming practice, I would recommend setting the GlideRecord variable to something a lot clearer, so that you know the datatype of the variable, eg. var caller --> var grCaller
