Språkversion: | ActionScript 3.0 |
Produktversion: | Flex 3 |
Körningsmiljöversioner: | Flash Player 9, AIR 1.1 |
Add a child node to a node at the specified index. This implementation does the following:
- If the
parent
parameter is null or undefined, inserts thechild
parameter at the specified index in the collection specified bymodel
parameter. - If the
parent
parameter has achildren
field or property, the method adds thechild
parameter to it at theindex
parameter location. In this case, themodel
parameter is not required. - If the
parent
parameter does not have achildren
field or property, the method adds thechildren
property to theparent
. The method then adds thechild
parameter to the parent at theindex
parameter location. In this case, themodel
parameter is not required. - If the
index
value is greater than the collection length or number of children in the parent, adds the object as the last child.
