JScript 支援索引屬性的使用，但不支援新屬性的宣告。

備註

Retrieves the parameter from the collection that matches the name specified in the styleName parameter. In C#, this property is the indexer for the StyleProperties class.

The objects referenced in the StyleProperties collections are the same as the Style collection, however the Style class differentiates between shared and non-shared properties.

In JScript, you can use the default indexed properties defined by a type, but you cannot explicitly define your own. However, specifying the expando attribute on a class automatically provides a default indexed property whose type is Object and whose index type is String.
