CRM Javascript Set Value to Null

Question

I want to clear a field in CRM using Javascript.  I have some code that pulls address information from the associated account record and displays it on the contact record.  However, if the account field is deleted it remains on the contact record because my script only updates changes.  Anyway how would I set a field to null.  

Can I do something like crmForm.all.new_accountaddresscity.DataValue = Null

Answer 1

Try this

Xrm.Page.data.entity.attributes.get("new_accountaddresscity").setValue(null);

Answer 2

I was actually right crmform.all.new_accountname.Datavalue = null;

Does the trick.
