This file demonstrates how the dojox.wire code can be used to do declarative |
|
wiring of events. Specifically, it shows how you can publish and subscribe |
|
to topics. In this case the setting of a value on one textbox triggers a |
|
publish of that value to a topic. Another invoke is wired to fire when |
|
values are published to that topic which is then displayed in another |
|
textbox. |

<!-------------------------------- Using dojox.wire, declaratively wire up the widgets. ---------------------------> |

|
<!-- |
|
Whenever a key is entered into the textbox, publish the value of it to a topic. |
|
--> |
|
<div dojoType="dojox.wire.ml.Action" |
|
id="action1" |
|
trigger="inputField" |
|
triggerEvent="onChange"> |
|
<div dojoType="dojox.wire.ml.Invocation" topic="sampleTopic" parameters="inputField.value"></div> |
|
</div> |
|
|
|
<!-- |
|
Whenever a value is published to a topic, set it as the value of the textbox by using Transfer to transfer the value from the |
|
topic publish to the target property. The underlying wire code will invoke the proper setter for the target, in this case |
|
it will invoke the dijit 'attr' function. |
