有的时候，我们想要同一个html随机调用加载不同的flash。这个时候，js就派上用场了。

至于兼容性。还待测试。

说说思路。

1.建立三个数组，分别存储所想要调用的flash的url、调用flash的宽高、浏览器的title。

var flash_path = ["a1.swf","a2.swf","a3.swf"] ;
var flash_attribute = [["1400","700"],["1280","700"],["1920","850"]];
var title_array = ["不明觉厉","十动然拒","人艰不拆"];

2.产生随机数，取到此次想调用的flash的url，宽高属性，以及title。

 var flash_rand = Math.floor(Math.random() * flash_path.length + 1);
var path = flash_path[flash_rand - 1];
var title = title_array[flash_rand - 1];

 

3.填充定义的html中嵌入flash的字符串。

 var flash_string = '\
<object id="FlashID" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="'+flash_attribute[flash_rand - 1][0]+'" height="'+flash_attribute[flash_rand - 1][1]+'">\
<param name="movie" value="'+ path +'" />\
<param name="allowScriptAccess" value="sameDomain"/>\
<param name="allowFullScreen" value="true" />\
<param name="allowFullScreenInteractive" value="true" />\
<param name="quality" value="high" />\
<param name="wmode" value="opaque" />\
<embed src= "'+ path +'" allowFullScreen="true" name="FlashID" quality="high" wmode="opaque" pluginspage="http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash" type="application/x-shockwave-flash" width="'+flash_attribute[flash_rand - 1][0]+'" height="'+flash_attribute[flash_rand - 1][1]+'"></embed>\
</object>';

 

4.将定义好的字符串写入文档。并关闭。

 document.write(flash_string);
document.close();

 

下边完整code：

<body bgcolor="#000000" style="margin:0px;text-align:center">
<script type="text/javascript">
initFlash();
function initFlash()
{
var flash_path = ["a1.swf","a2.swf","a3.swf"];
var flash_attribute = [["1400","700"],["1280","700"],["1920","850"]];
var title_array = ["不明觉厉","十动然拒","人艰不拆"];

var flash_rand = Math.floor(Math.random() * flash_path.length + 1);
var path = flash_path[flash_rand - 1];
var title = title_array[flash_rand - 1];

var flash_string = '\
<object id="FlashID" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="'+flash_attribute[flash_rand - 1][0]+'" height="'+flash_attribute[flash_rand - 1][1]+'">\
<param name="movie" value="'+ path +'" />\
<param name="allowScriptAccess" value="sameDomain"/>\
<param name="allowFullScreen" value="true" />\
<param name="allowFullScreenInteractive" value="true" />\
<param name="quality" value="high" />\
<param name="wmode" value="opaque" />\
<embed src= "'+ path +'" allowFullScreen="true" name="FlashID" quality="high" wmode="opaque" pluginspage="http://www.adobe.com/shockwave/download/download.cgi?P1_Prod_Version=ShockwaveFlash" type="application/x-shockwave-flash" width="'+flash_attribute[flash_rand - 1][0]+'" height="'+flash_attribute[flash_rand - 1][1]+'"></embed>\
</object>';
document.write(flash_string);
document.close();
}
</script>
</body>
