Remarks

The type of item you retrieve depends on the collection. Some collections expect only one object type, but others such as VisualCollection can contain multiple object types that share a common base type.

Examples

You can retrieve a specific child of a parent object by referencing the index of the collection of the parent object. The following JavaScript example shows how to retrieve a child of a parent Canvas object by using the GetItem method:

function getObject(parent, index)
{
    // Determine if the index is valid.
    if (index < parent.children.count)
    {
        // Retrieve the child object at the specified index in the collection.
        var object = parent.children.getItem(index);
    }

    return object;
}

Enumerating Child Objects

You can enumerate the child of a parent object by accessing the children collection of the parent object. The following JavaScript example shows how to enumerate the children of a parent Canvas object by using the GetItem method:

function getChildren(parent, index)
{
    // Enumerate the children of the Canvas object.
    for (i = 0; i < parent.children.count; i++)
    {
        var child = parent.children.getItem(i);

        // Display the index and type of the child object.
        alert(i + ": " + child.toString());
    }
}
