        </script>

    </head>



    <body>

    <div id="flashContent"></div>

   </body>

</html>

1.以上有问题部分曾经为"${width}","${height}",但是这样做swf会铺满整个屏幕。
2.我把宽度改为400px,高度改为300px，这样就可以显示如下

3.但是如果把宽度改为200，高度改为180的话，就只能如下

怎么改了大小那个flash安全设置的东西就出不来了？？

flex学的不多：[SWF(width="1000",height="750",backgroundColor="#D6E3F7",frameRate="100")] 我们知道使用Flash CS3 /Flash CS4 创建Flash 项目可以很方便的在项目属性面板上设置项目的舞台的大小，但当我们用Flex / Flash Builder 来做Flash 时候就没有直观的属性来设置舞台大小了。
