Populate Email Addresses of users selected in List Collector variable to Multi Line Text Variable

[Vinay52]

Hello, Requesters would be selecting the users using List Collector and requirement is to copy the email addresses of selected users with comma separated (Right Side of List collector) to another variable (Multi Line Text Variable). Text Variable to make it read only and visible to Fulfillers. 

I have tried creating script by looking some past examples but seems its not working. Any suggestions on what seems to be wrong please

Variable Details: 

Client Script 

Type - onChange, Variable Name - select_users  //list collector variable 

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }

  if(newValue === '') {
		g_form.clearValue('copied_from_list');
	}

	var gaPhone = new GlideAjax('getEmailAddress');
	gaPhone.addParam('sysparm_name', 'get_email');
	gaPhone.addParam('sysparm_users', newValue);
	gaPhone.getXMLAnswer(_handleResponse);

	function _handleResponse(response) {
		var answer = response;
		
		g_form.setValue('copied_from_list', answer);
	}
  
}

Script Include - Client Callable: Checked

var getEmailAddress = Class.create();
getEmailAddress.prototype = Object.extendsObject(AbstractAjaxProcessor, {
	
	get_email : function() {
		var userArr = this.getParameter('sysparm_users').split(',');
		var emailArr = [];

		for(var i = 0; i < userArr.length; i++) {
			var grUser = new GlideRecord('sys_user');

			if(grUser.get(userArr[i])) {
				emailArr.push(grUser.getValue('email'));
			}
		}
		emailArr.join();
		
		return emailArr.toString();
	},
		
    type: 'getEmailAddress'
	
});

Try below

Client script:

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }

  if(newValue === '') {
		g_form.clearValue('copied_from_list');
	}

	var gaPhone = new GlideAjax('getEmailAddress');
	gaPhone.addParam('sysparm_name', 'get_email');
	gaPhone.addParam('sysparm_users', newValue);
	gaPhone.getXMLAnswer(handleResponsefn);

	function handleResponsefn(response) {
		var answer = response.responseXML.documentElement.getAttribute('answer');
		
		g_form.setValue('copied_from_list', answer);
	}
  
}

Script include:

var getEmailAddress = Class.create();
getEmailAddress.prototype = Object.extendsObject(AbstractAjaxProcessor, {
	
	get_email : function() {
		var userArr = this.getParameter('sysparm_users');
                userArr = userArr.split(',');
		var emailArr = [];

		for(var i = 0; i < userArr.length; i++) {
			var grUser = new GlideRecord('sys_user');

			if(grUser.get(userArr[i])) {
				emailArr.push(grUser.getValue('email'));
			}
		}
		emailArr.join();
		
		return emailArr.toString();
	},
		
    type: 'getEmailAddress'
	
});

Place alert and see what response getting from the script include.

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }

  if(newValue === '') {
		g_form.clearValue('copied_from_list');
	}

	var gaPhone = new GlideAjax('getEmailAddress');
	gaPhone.addParam('sysparm_name', 'get_email');
	gaPhone.addParam('sysparm_users', newValue);
	gaPhone.getXMLAnswer(handleResponsefn);

	function handleResponsefn(response) {
		var answer = response.responseXML.documentElement.getAttribute('answer');
		alert(answer);
		g_form.setValue('copied_from_list', answer);
	}
  
}

Sorry, I didn't realize that you are using synchronous method, try the below asynchronous type method

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }

  if(newValue === '') {
		g_form.clearValue('copied_from_list');
	}

	var gaPhone = new GlideAjax('getEmailAddress');
	gaPhone.addParam('sysparm_name', 'get_email');
	gaPhone.addParam('sysparm_users', newValue);
	gaPhone.getXML(handleResponsefn);

	function handleResponsefn(response) {
		var answer = response.responseXML.documentElement.getAttribute('answer');
		
		g_form.setValue('copied_from_list', answer);
	}
  
}
