html - 我该如何更新此代码

Question

   <object height="25" width="75" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=5,0,0,0" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000">
        <param value="http://click-here-to-listen.com/players/iaPlay13.swf?x=1058286910FTRZGK" name="movie"/> 
        <param value="high" name="quality"/>
        <param value="#FFFFFF" name="bgcolor"/> 
        <param value="opaque" name="wmode"/>
        <embed height="25" width="75" wmode="opaque" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" bgcolor="#FFFFFF" quality="high" src="http://click-here-to-listen.com/players/iaPlay13.swf?x=1058286910FTRZGK"/>
    </object>

我必须将这个遗留标记插入到我正在构建的新站点中。问题是它使用 <embed>标签。

我会直接取消 <embed> 吗？并为那些没有闪存的内容添加一些内容作为替代？基本上，我只是想将这段 html 带入 21 世纪。

您可以嵌套对象元素以显示备选方案。 W3C 对其进行了解释 here .我在下面复制了一个片段:

One significant consequence of the OBJECT element's design is that it offers a mechanism for specifying alternate object renderings; each embedded OBJECT declaration may specify alternate content types. If a user agent cannot render the outermost OBJECT, it tries to render the contents, which may be another OBJECT element, etc.

In the following example, we embed several OBJECT declarations to illustrate how alternate renderings work. A user agent will attempt to render the first OBJECT element it can, in the following order: (1) an Earth applet written in the Python language, (2) an MPEG animation of the Earth, (3) a GIF image of the Earth, (4) alternate text.

<P>                 <!-- First, try the Python applet -->
<OBJECT title="The Earth as seen from space" 
    classid="http://www.observer.mars/TheEarth.py">
                <!-- Else, try the MPEG video -->
    <OBJECT data="TheEarth.mpeg" type="application/mpeg">
                <!-- Else, try the GIF image -->
      <OBJECT data="TheEarth.gif" type="image/gif">
                <!-- Else render the text -->
       The <STRONG>Earth</STRONG> as seen from space.
     </OBJECT>
   </OBJECT>
</OBJECT>
