If you specify an object as the location, the object must specify two properties:
The property is an array of strings, as discussed above, except that one or more of the
path
specified strings may be the special token
must be a corresponding index item in
index into arrays. The index item can be any EndPoint object. This type of location can be
applied to ActionScript data only—not XML. (See Example 3 below.)
Example
Example 1: This example uses an XPath expression to specify the location of a node named
an XML object:
var sourceEndPoint = new mx.databinding.EndPoint();
var sourcObj=new Object();
sourceObj.xml=new XML("<zip>94103</zip>");
sourceEndPoint.component=sourceObj;
sourceEndPoint.property="xml";
sourceEndPoint.location="/zip";//
Example 2: This example uses an array of strings to "drill down" to a nested movie clip property:
var sourceEndPoint = new mx.data.binding.EndPoint();
// assume movieClip1.ball.position exists
sourceEndPoint.component=movieClip1;
sourceEndPoint.property="ball";
// access movieClip1.ball.position.x
sourceEndPoint.location=["position","x"];
Example 3: This example shows how to use an object to specify the location of a data field in a
complex data structure:
var city=new Object();
city.theaters = [{theater: "t1", movies: [{name: "Good,Bad,Ugly"},
{name:"Matrix Reloaded"}]}, {theater: "t2", movies: [{name: "Gladiator"},
{name: "Catch me if you can"}]}];
var srcEndPoint = new EndPoint();
srcEndPoint.component=city;
srcEndPoint.property="theaters";
srcEndPoint.location = {path: ["[n]","movies","[n]","name"], indices:
[{constant:0},{constant:0}]};
EndPoint.property
