Flash播放器自从升级到Flash Player 9,0,28,0，也可以使网页中的Flash通过一个简单的按钮实现全屏显示，和一些视频网站中的效果基本相同，但是在这个教程里是没有使用Javascript脚本的啊！
需要我们在网页中插入Flash代码时，必须加上下面的代码：
<param name="allowFullScreen" value="true" />
首先看一下效果和源文件
启动Flash，制作一个按钮元件，然后把按钮放到主场景中，为按钮添加代码：
on(press){
toggleFullScreen();
}
函数toggleFullScreen()是主要来控制窗口，函数定义如下。
//Don't scale the movie when the stage size changes
Stage.scaleMode="noScale";
//Align the stage to the top left
Stage.align = "TL";
//Function to toggle between fullscreen and normal size
//the toggle fullscreen button calls this function when pressed
function toggleFullScreen(){
//if normal size, go to fullscreen, else go to normal size
if(Stage["displayState"]=="normal"){
Stage["displayState"]="fullScreen";
}else{
Stage["displayState"]="normal";
}
}
//Create a listener for each time the Stage is resized
var resizeListener:Object = new Object();
//Called each time the stage is resized
resizeListener.onResize = function () {
//Move the button to the center of the screen
toggleFullScreenButton._x=Stage.width/2;
toggleFullScreenButton._y=Stage.height/2;
}
//Add the listener to Stage
Stage.addListener(resizeListener);
这样就制作好了！
当我们把上面制作的Flash插入到网页中时，具体代码如下：
<object data="http://www.webjx.com/upfiles/20071018/20071018224608_fullscreen.swf"
type="application/x-shockwave-flash" width="400" height="200" >
<param name="movie" value="http://www.webjx.com/upfiles/20071018/20071018224608_fullscreen.swf" />
<param name="allowFullScreen" value="true" />
</object>
就可以看到前面的全屏和收缩效果了！
