本文介绍如何建立一个舞台随窗体尺寸大小动态改变的Flash例子，使用的脚本为AS3.0
1.建立工程
2.新建一个AS文件，主要实现舞台的动态缩放功能
代码如下：
package {
import flash.display.Sprite;
import flash.display.Stage;
import flash.events.Event;
_height = String( stage.stageHeight );
if (browserHacks == null) browserHacks = [HACK_MARGIN_BOTTOM,HACK_IE_REPARENT,HACK_UNIQUE_ID];
this.containerId = containerId;
public static const HACK_UNIQUE_ID:String = "uniqueId"; //If you put both an embed and object tag with the same id, this tries to compensate
private var stage:Stage;
public static var INSERT_BROWSER_HACKS:XML =
<script><![CDATA[
function (containerId,browserHacks) {
var objNode = document.getElementById(containerId);
if (objNode.nodeName.toLowerCase() == "div") return;
private var containerId:String;
private var _width:String;
private var _minWidth:String;
private var _maxWidth:String;
private var _height:String;
private var _minHeight:String;
return (getFileName(fullPath) == targetSwfName);
}
var targetSwfName = getFileName(swfFullPath);
//Look through the embed nodes for one that matches our swf name
(navigator.userAgent.toLowerCase().indexOf("opera") != -1)) &&
(objNode.nodeName.toLowerCase() == "object") &&
(browserHacks.indexOf("uniqueId") != -1)
) {
public static const HACK_IE_REPARENT:String = "IEReparent"; //In IE, create a container div which encapsulates the object tag in order to hav min/max sizes work
//If you make the mistake of naming the object and embed nodes with the same id, firefox will get confused
if (((navigator.userAgent.toLowerCase().indexOf("firefox") != -1) ||
//Check if we have an embed tag inside of us, if so, ignore the obj tag

this.stage = stage;
timerSprite = new Sprite();
_width = String( stage.stageWidth );
if (matchesTarget(paramNodes[k].attributes["value"].nodeValue)) {
ensureId(nodes[j]);
return nodes[j].attributes["id"].nodeValue;
}
}
}
}
return null;
}
]]></script>;
return fileName;
}
var ensureId = function(node) {
if (node.attributes["id"] == null) {
node.setAttribute("id",'swf'+new Date().getTime());
}
}
var matchesTarget = function(fullPath) {
if (this.containerId == null) this.containerId = ExternalInterface.objectID;
if (this.containerId == null) this.containerId = ExternalInterface.call(JSScripts.GET_FLASH_ID, stage.loaderInfo.url);
