how to get display value?

[sakata kenichi]

The official reference does not specify any arguments for the getDisplayValue () method.

Therefore, I think the usage of current. <FieldName> .getDisplayValue () is correct,

At this time, an error will occur if fieldName does not exist.

It is hard to check the existence of fieldName every time.

Is there a way to get a displayvalue that works even if fieldName doesn't exist, like current.getValue ("fieldName")?

yes ,we have current.getDisplayValue('assigned_to'); it won't throw error even when the field is empty!!

Hi. Thank you for your reply.
I understand that you don't throw errors in the way you wrote.
Sorry, But the usage of "current.getDisplayValue ('assigned_to')" is not officially documented, so we can't determine if it's the correct method.

Is there a document that can be recognized as an official usage?

[SatheeshKumar]

I can't find any official document for this!!.

Haha ..!! Most of the service portal methods are not officially documented by servicenow but we are still using them 🙂

Hi,

you can check whether field is valid or not before using this

var isValid = current.isValidField(<FieldName>);

if(isValid){

current.<FieldName>.getDisplayValue();

}

Mark ✅ Correct if this solves your issue and also mark 👍 Helpful if you find my response worthy based on the impact.
Thanks
