编写Flash AS代码实现按钮触发全屏动画

Flash播放器升级到Flash Player 9,0,28,0后可以使网页中的Flash通过一个简单的按钮实现全屏显示,这和一些视频网站中的效果基本相同,下面我们看看具体怎么实现,不需使用Javascript脚本。 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" />
下面我们介绍Flash中的做法。
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);
这样就定义好了!
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="你的swf文件地址"
type="application/x-shockwave-flash"
width="400" height="200" >
<param name="movie"
value="你的swf文件地址"
/>
<
param name="
allowFullScreen"
value="
true"
/>
</object>
这样就可以看到前面的全屏和收缩效果了!
