Many properties, methods and event handlers are inherited from the Input object class. Refer to topics grouped with the "Input" prefix for details of common functionality across all subclasses of the Input object superclass.
There isn't really a FileUpload object class, but it is helpful when trying to understand the wide variety of input element types, if we can reduce the complexity by discussing only the properties and methods of a file upload. In actual fact, the object is represented as an item of the Input object class.
Unlike MSIE, Netscape Navigator does not support the defaultValue property or the select() method for this subclass of the Input object.
To be able to upload a file under script control, you must have the UniversalFileRead privilege granted to the script.
