This library provides access to the HCL Domino® back-end.
NotesItem (JavaScript™)
Represents a discrete value or set of values in a document. The client interface displays items in a document through fields on a form. When a field on a form and an item in a document have the same name, the field displays the item (for example, the Subject field displays the Subject item). All items in a document are accessible programmatically, regardless of what form is used to display the document in the user interface.
setValueCustomData (NotesItem - JavaScript™)
Sets the value of an item to custom data from an object.

Defined in

setValueCustomData(Object:any)
: void

setValueCustomData(datatypename:string, Object:any) : void


Parameter	Description
`Object`	An object that contains the custom data. The class that defines this object must implement `Serializable`. If desired, you can override `readObject` and `writeObject`.
`datatypename`	A name for the data type. When getting custom data, use this name for verification.

The new value replaces the existing value.

To keep the changes, you must call NotesDocument.save after calling this method.
