propertyIsEnumerable Property (JScript 5.6)


object.propertyIsEnumerable(proName)

object: Required. Instance of an object.

proName: Required. String value of a property name.

The propertyIsEnumerable property returns true if proName exists in object and can be enumerated using a ForIn loop. The propertyIsEnumerable property returns false if object does not have a property of the specified name or if the specified property is not enumerable. Typically, predefined properties are not enumerable while user-defined properties are always enumerable.

The propertyIsEnumerable property does not consider objects in the prototype chain.
