LoadVars class

setAttributes()

setAttributes(object, propName, enumerable, readonly, permanent)

Prevents certain methods and properties from being enumerated, written, and deleted. In a server-side script, all

properties in an object are enumerable, writable, and deletable by default. Call

setAttributes() to change the default

attributes of a property or to define constants.

Parameters

object An Object.

propName A string indicating the name of the property in the object parameter. Setting attributes on nonexistent

properties has no effect.

enumerable One of the following values: true, false, or null. Makes a property enumerable if true or

nonenumerable if

false; a null value leaves this attribute unchanged. Nonenumerable properties are hidden from

enumerations (

forvariinobj).

readonly One of the following values: true, false, or null. Makes a property read-only if true or writable if false;

null value leaves this attribute unchanged. Any attempt to assign a new value is ignored. Typically, you assign a value

to a property while the property is writable and then make the property read-only.
