value - within an HTML tag, value=... will set
the field to that value, and if id=FieldId is also present, then scripting languages such as
JavaScript can read or set the value via FieldId.value.
(But see Intrinsic Events for problem with XML data.)
valueOf - a JavaScript method built into every object type,
and automatically invoked when JavaScript encountering an object where a primitive value is expected.
If an object has no primitive value, valueOf returns the object itself.
The following object types are those for which the valueOf method is most useful. Most other objects have no primitive value.
Number; Boolean; String; Function - e.g. typeof funObj returns "object", but typeof funObj.valueOf() returns "function".
The default valueOf method can be overridden (takes no arguments). e.g.
myNumberType.prototype.valueOf = new Function(functionText)
See String and parseInt and Number.
VAN EDI: Value-Added Network.
VBScript is a scripting language which can be used in HTML documents in a
similar way to JavaScript, and also in the macros in most Microsoft packages.
