使用者自主選擇安裝flash

<script type="text/javascript" language="JavaScript">
<!-- start JS detection
FlashMode =0;
if (navigator.plugins && navigator.plugins.length >0)
{
    if (navigator.plugins["Shockwave Flash"])
   {
        var plugin_version = 0;
        var

 words = navigator.plugins["Shockwave Flash"].description.split(" ");
        for (var i = 0; i < words.length; ++i)
        {
            if (isNaN(parseInt(words[i])))
            continue;
            plugin_version = words[i];
        }
        if (plugin_version >= 5)
