childrenField | 屬性 |
childrenField:String| 語言版本: | ActionScript 3.0 |
| 產品版本: | Flex 3 |
| 執行階段版本: | Flash Player 9, AIR 1.1 |
Indicates the field name to be used to detect children objects in
a data item.
By default, all subnodes are considered as children for
XML data, and the children property is used for the Object data type.
This is helpful in adapting to a data format that uses custom data fields
to represent children.
