This file demonstrates how the dojox.wire code can be used to do declarative
|
||
|
|
wiring of events. Specifically, it shows how you can chain actions together
|
||
|
|
in a sequence. In this case the setting of a value on one textbox triggers a
|
||
|
|
copy over to another textbox. That in turn triggers yet another copy to another
|
||
|
|
text box.

Note that this uses the basic 'property' form of copying the property over and setting it. The Wire
|
||
|
|
code supports both getX and setX functions of setting a property as well as direct access. It first looks
|
||
|
|
for the getX/setX functions and if present, uses them. If missing, it will just do direct access. Because
|
||
|
|
of the standard getValue/setValue API of dijit form widgets, these transfers work really well and are very compact.
