See the Example section for
EndPoint class (Flash Professional only)
ActionScript Class Name
The EndPoint class defines the source or destination of a binding. EndPoint objects define a
constant value, component property, or particular field of a component property, from which you
can get data, or to which you can assign data. They can also define an event, or list of events, that
a Binding object listens for; when the specified event occurs, the binding executes.
When you create a new binding with the Binding class constructor, you pass it two EndPoint
objects: one for the source and one for the destination.
new mx.data.binding.Binding(srcEndPoint, destEndPoint);
The EndPoint objects,
var srcEndPoint = new mx.data.binding.EndPoint();
var destEndPoint = new mx.data.binding.EndPoint();
srcEndPoint.component = source_txt;
srcEndPoint.property = "text";
srcEndPoint.event = "focusOut";
destEndPoint.component = dest_txt;
destEndPoint.property = "text";
In English, the above code means "When the source text field loses focus, copy the value of its
property into the
text
You can also pass generic ActionScript objects to the Binding constructor, rather than passing
explicitly constructed EndPoint objects. The only requirement is that the objects define the
required EndPoint properties,
shown above.
var srcEndPoint = {component:source_txt, property:"text"};
var destEndPoint = {component:dest_txt, property:"text"};
new mx.data.binding.Binding(srcEndPoint, destEndPoint);
Note: To make this class available at runtime, you must include the data binding classes in your FLA
document.
