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. |

<!-------------------------------- Using dojox.wire, declaratively wire up the widgets. ---------------------------> |
|
|
|
<!-- |
|
This is an example of using the declarative data value definition. |
|
These are effectively declarative variables to act as placeholders |
|
for data values. |
|
--> |
|
<div dojoType="dojox.wire.ml.Data" |
|
id="data"> |
|
<div dojoType="dojox.wire.ml.DataProperty" |
|
name="tempData" |
|
value=""> |
|
</div> |
|
<div dojoType="dojox.wire.ml.DataProperty" |
|
name="value" |
|
value="value"> |
|
</div> |
|
</div> |
|
|
|
<!-- |
|
Whenever a key is entered into the textbox, copy the value somewhere, then invoke a method on another widget, in this case |
|
on just another text box. |
|
--> |
|
<div dojoType="dojox.wire.ml.Action" |
|
id="action1" |
|
trigger="inputField" |
|
triggerEvent="onChange"> |
|
<div dojoType="dojox.wire.ml.Transfer" source="inputField.value" target="data.tempData"></div> |
|
<div dojoType="dojox.wire.ml.Invocation" id="targetCopy" object="targetField1" method="set" parameters="data.value, data.tempData"></div> |
|
</div> |
|
|
|
<!-- |
|
Whenever the primary cloning invocation completes, invoke a secondary cloning action. |
|
--> |
|
<div dojoType="dojox.wire.ml.Action" |
|
id="action2" |
|
trigger="targetCopy" |
|
triggerEvent="onComplete"> |

<!-- |
|
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. |
