LoadVars class

setAttributes()

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

Prevents certain methods and properties from being enumerated, writable, and deletable. 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 nonenu-

merable if

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

ations (

for var i in obj).

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

false; a 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.

permanent One of the following values: true, false, or null. Makes a property permanent (nondeletable) if

true or deletable if false; a null value leaves this attribute unchanged. Any attempt to delete a permanent property

(by calling

delete obj.prop) is ignored.

Example

The following code prevents the

resolve() method from appearing in enumerations:

Object.prototype.__resolve = function(methodName){ ... };

setAttributes(Object.prototype, "__resolve", false, null, null);

The following example creates three constants on a Constants object and makes them permanent and read-only:

Constants.KILO = 1000;

setAttributes(Constants, "KILO", null, true, true);

Constants.MEGA = 1000*Constants.KILO;
