Clearing value onChange client script when a Reference field was emptied

[Piotr Ba_amut]

I've got a problem with clearing values in fields x,y,z when a Reference was emptied (user removed as a value). It concerns catalog client script. Am trying to manipulate with "newValue", "odValue", but in vain..

Code: 

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '' ) {
      return;
   }
 
	var req = g_form.getReference('fru_requested_for',pullAttributes);   //call to the sys_user reference field
	//below is the callBack function to pull user's attributes
	

	function pullAttributes(req) {
		
		
		
		var h = g_form.getDisplayBox('fru_requested_for').value;
		if (newValue !=='') {
		alert("ustawiono");
		g_form.setValue('fru_first_name',req.first_name);
		g_form.setValue('fru_last_name',req.last_name);
		g_form.setValue('fru_email',req.email);
		g_form.setValue('fru_employee_id',req.employee_number);
		} else if (newValue == '')
		
		
		  {
		alert("test");
		g_form.setValue('fru_first_name','');
		g_form.clearValue('fru_last_name');
		g_form.clearValue('fru_email');
		g_form.clearValue('fru_employee_id');	 
		    }
	
	}
 
}

Try this and let me know what you get.

function onChange(control, oldValue, newValue, isLoading) {
	if (isLoading ) {
		return;
	}
	
	// Call to the sys_user reference field
	var req = g_form.getReference('fru_requested_for', pullAttributes); 
}

// Callback function to pull user's attributes
function pullAttributes(req) {
	if (newValue != '') {
		alert("Not empty");
		g_form.setValue('fru_first_name', req.first_name);
		g_form.setValue('fru_last_name', req.last_name);
		g_form.setValue('fru_email', req.email);
		g_form.setValue('fru_employee_id', req.employee_number);
	}
	else {
		alert("Empty");
		g_form.clearValue('fru_first_name','');
		g_form.clearValue('fru_last_name');
		g_form.clearValue('fru_email');
		g_form.clearValue('fru_employee_id');
	}
}

Mark, the same. Value are setup, but no both alerts, nor removing values when emptying reference. Maybe that's a bug in Jakarta, isn't it ?

Mark, so to speak... You're the real ServiceNow GURU. the code has worked with the newValue=='' operator. 

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading) {
    return;
   }
 
	var req = g_form.getReference('fru_requested_for',pullAttributes);   //call to the sys_user reference field
	//below is the callBack function to pull user's attributes
	

	function pullAttributes(req) {
		
		
		
		//var h = g_form.getDisplayBox('fru_requested_for').value;
		
		
		g_form.setValue('fru_first_name',req.first_name);
		g_form.setValue('fru_last_name',req.last_name);
		g_form.setValue('fru_email',req.email);
		g_form.setValue('fru_employee_id',req.employee_number);
		}
		
		if (newValue =='') {
			
		
		g_form.clearValue('fru_first_name');
 		g_form.clearValue('fru_last_name');
 		g_form.clearValue('fru_email');
 		g_form.clearValue('fru_employee_id');	 
		    
	
	}


}
