各位在设计、制作或者处理自己的blog的时候会遇到插入flash文件，自己在IE打开这个页面后，flash上面会浮现一个虚框，需要点击一次后才可以操作。程序繁琐，不免让喜欢简单的朋友觉得复杂。另外虚框也影响了网页的整体美观性和体验性。
这里分享一段代码，只要在网页中插入，所有swf文件的虚框将会消失，是不是很得意呢？哈哈，代码如下：
将其保存为flash_no.js，在你需要的前台页面head中加入：
<head>
…
<script type="text/javascript" src="script/flash_no.js"></script>
</head>
flash_no.js:
/**
