Flash Player文件
具体步骤 代码示例：
<object id="movie" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,0,0" width="150" height="100" align="middle">
<param name="allowScriptAccess" value="sameDomain" />
<param name="movie" value="demo.swf" />
<param name="menu" value="false" />
<param name="quality" value="high" />
<param name="bgcolor" value="#ffcc33" />
<embed src="demo.swf" menu="false" quality="high" bgcolor="#ffcc33" width="150" height="100" name="movie" align="middle" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />
</object><br>
<button onClick="movie.IsPlaying()?movie.StopPlay():movie.Play()">Pause</button>
提示：本例中的核心语句
movie.IsPlaying()?movie.StopPlay():movie.Play()
用了三目运算符，相当于
if(movie.IsPlaying()){
movie.StopPlay()
} else{
movie.Play()
}
特别提示
本例代码运行后的效果如图5.3.2所示，单击【Pause】按钮时如果Flash动画正在播放，则停止播放动画，否则播放动画。
图5.3.2 暂停Flash动画的按钮的实现
特别说明
本例主要用到Flash对象的IsPlaying()方法来测试Flash动画的当前播放状态，然后分别调用Play()方法和StopPlay()方法来实现暂停的功能。
IsPlaying() 如果动画当前正在播放，返回为 true，反之返回 false 。
