onChange client script returning 'undefined'

[lando321]

Hello all,

I am trying to populate the dept code with an onChange client script, but it keeps returning 'undefined' when i attempt to dot walk to the id field on the department table. When i use getDisplayValue() the field does not return anything at all. Would greatly appreciate any help.

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }
if (newValue){
	var caller = g_form.getReference('name', popDept);
}
	function popDept(caller){
  g_form.setValue('department_code', caller.department_id);
	}  
}

Hello,

Can you paste the screenshot of the name field?

Is it a reference field to the user table if the name is the correct field and on what field is the onchange script triggering?

Sure @Saurav11

Hello,

So it is basically you have to dot walk two times, please use the below code:-

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


   var caller = g_form.getReference('name');
   var dept = caller.department;
   if (dept) {
       var grDept = new GlideRecord('cmn_department');
       if (grDept.get(dept)) {
            g_form.setValue('department_code', grDept.department_id);
       }
   }
}

Please mark my answer as correct based on Impact.

Im still getting 'undefined' and i am cueing the onChange from the name variable on the form. Does it matter that this catalog client script is in a variable set?

[lando321]

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading || newValue == '') {
      return;
   }
//if (newValue){
	var caller = g_form.getReference('name');
	var dept = caller.department;
	if (dept){
		var grDept = new GlideRecord('cmn_department');
		if (grDept.get(dept)){
			g_form.setValue('department_code', grDept.id);
		}
	}
}

One small tweak, worked for me, swapped out department_id with just "id"
