Javascript 为什么Firefox不缓存swf对象？

我正在使用swf对象在我的网页上嵌入swf。相同的swf显示在我的网页上的5-6个链接上，但每次加载swf都需要相同的时间，知道吗

这是密码

var href = 'http://xyz.com/dialog/demo.swf';
var flashvars = {};
var params = {};
params.wmode = "transparent";
params.allowscriptaccess = "always";
params.swliveconnect = "true";
params.menu = "false";
var attributes = {};
attributes.id = "c2c";
attributes.name = "c2c";
swfobject.embedSWF(href+"?nocache="+siteID+"&phone="+num+"&siteid="+siteID, "infBox", "100", "60", "9.0.0", "http://xyz.com/dialog/expressInstall.swf", flashvars, params, attributes);

试试这种代码

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="502" height="250">
    <param name="movie" value="swffile.swf" />
    <param name="quality" value="high" />
    <embed src="swffile.swf" quality="high" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="502" height="250"></embed>
  </object>

如果您使用dreamweaver作为您的编辑器，在代码的下一行中的菜单“插入->媒体->闪存”中，您可能会得到这个结果。您明确允许swfobject不缓存您的电影

swfobject.embedSWF(href+"?nocache="+siteID+"&phone="+num+"&siteid="+siteID, "infBox", "100", "60", "9.0.0", "http://xyz.com/dialog/expressInstall.swf", flashvars, params, attributes);

您需要删除或更新nocache变量。在代码中没有指定，但我确信变量“num”在代码中的某个地方被随机分配

建议1-完全删除无缓存：

swfobject.embedSWF(href, "infBox", "100", "60", "9.0.0", "http://xyz.com/dialog/expressInstall.swf", flashvars, params, attributes);

解决方案2-仅从swf地址查询中删除num变量

swfobject.embedSWF(href+"?nocache="+siteID+"&phone="+"&siteid="+siteID, "infBox", "100", "60", "9.0.0", "http://xyz.com/dialog/expressInstall.swf", flashvars, params, attributes);

在这种情况下，您可以一起删除无缓存或删除num变量。。
