Flex程序的全屏幕显示

 看到官方的一片讲解如何在Flash Player 9下全屏幕显示Flash的文章，原文地址如下：

 Exploring full-screen mode in Flash Player 9 ，照葫芦画弧，这里我只贴一下AS3的代码：

package
... {
    import flash.display.Sprite;
    import flash.ui.ContextMenu;
    import flash.ui.ContextMenuItem;
    import flash.events.ContextMenuEvent;
    import flash.display.StageScaleMode;
    import flash.display.StageDisplayState;
    import flash.system.Security;
    import flash.system.SecurityPanel;
    import flash.system.fscommand;

    public class FullScreen_demo extends Sprite
    ...{
        public function FullScreen_demo()
        ...{
            // create the context menu, remove the built-in items,
            // and add our custom items
            var fullscreenCM:ContextMenu = new ContextMenu();
            fullscreenCM.addEventListener(ContextMenuEvent.MENU_SELECT, menuHandler);
            fullscreenCM.hideBuiltInItems();
            
            var fs:ContextMenuItem = new ContextMenuItem("Go Full Screen" );
            fs.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT, goFullScreen);
            fullscreenCM.customItems.push( fs );
            
            var xfs:ContextMenuItem = new ContextMenuItem("Exit Full Screen");
            xfs.addEventListener(ContextMenuEvent.MENU_ITEM_SELECT, exitFullScreen);
            fullscreenCM.customItems.push( xfs );
            
            // finally, attach the context menu to a movieclip
            this.contextMenu = fullscreenCM;
        }
        
        private function goFullScreen(e:ContextMenuEvent):void...{
            this.stage.displayState = StageDisplayState.FULL_SCREEN; //设置为全屏
        }
        private function exitFullScreen(e: ContextMenuEvent ):void...{
            this.stage.displayState = StageDisplayState.NORMAL;
        }
        private function menuHandler(e:ContextMenuEvent):void...{
            if (stage.displayState == StageDisplayState.NORMAL)
               ...{
                  e.target.customItems[0].enabled = true;
                  e.target.customItems[1].enabled = false;
               }
               else
               ...{
                  e.target.customItems[0].enabled = false;
                  e.target.customItems[1].enabled = true;
               }
        }
    }
}

 

根据说明再修改HTML文件内容：

< object  classid ="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"
 codebase ="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,18,0"
 width ="600"   height ="400"  id ="fullscreen"  align ="middle" >
< param  name ="allowFullScreen"  value ="true"   />
< param  name ="movie"  value ="fullscreen.swf"   />
< param  name ="bgcolor"  value ="#333333"   />
< embed  src ="fullscreen.swf"  allowFullScreen ="true"  bgcolor ="#333333"  width ="600"  height ="400"
 name ="fullscreen"  align ="middle"  type ="application/x-shockwave-flash"  
 pluginspage ="http://www.macromedia.com/go/getflashplayer"   />
</ object >

 

关键是这一句：<param name="allowFullScreen" value="true" /> ，一切就绪后，运行，却弹出如下错误：

SecurityError: Error #2152: 不允许使用全屏模式。

奇怪了，怎么不行呢，google一番，也没查到具体原因，却找到另一个方法实现全屏，一个SWFObject.js脚本(地址：http://blog.deconcept.com/swfobject/)，做起来也挺简单，SWF代码都不变，改一下HTML文件，内容如下：

< script  type ="text/javascript"  src ="swfobject.js" ></ script >
         < style  type ="text/css" > ...
            body
            {...}{
                background-color: #869ca7;
            }
         </ style >
</ head >

< body >
< div  id ="fabchannel_base_templateContainer" > You need the Flash Player version 9.0.18.60 or higher and a JavaScript enabled browser to view this site </ div >
< script  type ="text/javascript" > ...
            // <!--
            var ignoredParams = ...{src: 1, bgcolor: 1};
            var params = String('src="FullScreen_demo.swf" menu="true" quality="high" bgcolor="#869ca7" ').split(" ");
            var swf = new SWFObject("FullScreen_demo.swf", "fabchannel_base_template", "960", "605", "9.0.18.60", "#869ca7");
            swf.addParam("align", "middle");
            swf.addParam("allowFullScreen", "true");
            for(var i = 0; i < params.length; i++)
            ...{
                var paramName = params[i].split("=")[0];
                var paramValue = params[i].split(""")[1];
                
                if(ignoredParams[paramName] != 1 && paramName != "")
                ...{
                    swf.addParam(paramName, paramValue);
                }
            }
            swf.write("fabchannel_base_templateContainer");
            // -->
         </ script >
</ body >

只要把上面红色字的改成你的swf文件就可以了，是不是很简单，现在还不明白官方的那个例子怎么不行了，希望知情者告知，谢谢。
