flash object (fl)

Last updated 5/2/2011

Returns

An array of generic objects. Use the .obj property of each item in the array to get the element object. Each object has

the following properties:

keyframe, layer, timeline, and parent. You can use these properties to access the

hierarchy of the object.

You can also access methods and properties for the layer and timeline values; they are equivalent to the Layer object

and the Timeline object, respectively.

The second and third examples in the Examples section show how to access these properties.

Description

Method; exposes elements of a specified element type in a document.

Note: In some cases, this method works only when run as a command from within a FLA file, not when you are currently

viewing or editing the JSFL file.

Example

The following example searches the current document for text fields and then changes their contents:

var doc = fl.getDocumentDOM();

var typeToSearchFor = "text";

var results = fl.findObjectInDocByType(typeToSearchFor, doc);

if (results.length > 0) {

for (var i = 0; i < results.length; i++) {

results[i].obj.setTextString("new text");

}

alert("success, found " + results.length + " objects");

}

else {

alert("failed, no objects of type " + typeToSearchFor + " found");

}

The following example shows how to access the special properties of the object returned by this method:

var doc = fl.getDocumentDOM();

var resultsArray = findObjectInDocByType("text", doc);

if (resultsArray.length > 0)

{

var firstItem = resultsArray[0];

// firstItem.obj- This is the element object that was found.

// You can access the following properties of this object:

// firstItem.keyframe- The keyframe that the element is on.

// firstItem.layer- The layer that the keyframe is on.

// firstItem.timeline- The timeline that the layer is on.

// firstItem.parent- The parent of the timeline. For example,

// the timeline might be in a symbol instance.

}

The following example shows how to back up the DOM to find the name of a layer on which a text field was found,

using the resultArray.obj object:

1 2 ... 252 253 254 255 256 257 258 259 260 261 262 ... 564 565
