去除flash边框虚框的方法代码

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:

    ie = (ver >=6)
}else if (navigator.userAgent.indexOf("Opera")!=-1) {
    var versionindex=navigator.userAgent.indexOf("Opera")+6
    if (parseInt(navigator.userAgent.charAt(versionindex))>=9)
    opera9 = true;
}
var oswap = (ie || opera9)

    document.write ("<style id='hideObject'> object{display:none;} </style>");
