This file demonstrates how the dojox.wire code can be used to do declarative
|
|
|
3 |
wiring of properties/attributes of some object to the properties/attributes of
|
|
|
4 |
another object. It specifically uses the Child (Composite) wire type to perform
|
|
|
5 |
the mapping.
|
|
|
6 |
|
|
|
7 |
Note that this demo expects dojo, digit, and dojox to all be peers in the same directory
|
|
|
8 |
in order for it to execute.
