Question

我有一个简单的Flash登陆页面，它有2个动态旋转图像的区域和2个动态文本区域。所有区域都由单个XML文件控制。

当我更改XML文件中的文本内容或者更新文件夹中的图像并在我的adobe flash编辑器中进行测试时，更改是即时的。当我打开firefox或IE时，带有flash文件的页面不会反映更新。我删除了我的历史，告诉adobe flash不允许任何闪存存储在我的计算机上，关闭并重新加载页面但无济于事。我可以获取要刷新的内容的唯一方法是重命名文件，保存在新文件夹中并重命名它绘制的xml页面。我甚至在最后添加了kiosk.swf？id =＃randrange（10000,99999）#ctring，看看它是否让浏览器认为它是一个新文件。没有重命名和移动文件/文件夹将使浏览器显示新内容。

这个简单的Flash页面可以作为自助服务终端的目标网页。

    <style type="text/css" media="screen">
        body { margin:0; padding:0; overflow:hidden;background-color:#153d6f; }
        #myID   { height:100%;background-color:#153d6f; }
    </style>    
    <script type="text/javascript" src="swfobject.js"></script>
    <script type="text/javascript" src="swffit.js"></script>
   <cfoutput>
       <script type="text/javascript">
            swfobject.embedSWF("kiosk.swf?id=#randrange(10000,99999)#", "myID", "100%", "100%", "9.0.0", "expressInstall.swf");
            swffit.fit("myID");
        </script>
   </cfoutput> 

</head>
<body>
    <div id="myID"></div>
</body>

Answer 1

要避免在actionscript中缓存，请添加“？”然后在你正在加载的项目的URL末尾有一些独特的字符（无论是图像，swfs，xml等等）。例如：

var cacheBuster:String = "?"+(new Date()).time.toString();
my_loader.load(new URLRequest(my_url+cacheBuster));

new Date（）。time返回自1-1-1970以来的毫秒数，因此它是生成唯一字符串的不错选择。

如果它的kiosk.swf即缓存，则javascript非常相似：

var cacheBuster = "?"+(new Date()).getTime().toString();
swfobject.embedSWF("kiosk.swf"+cacheBuster, ....
