flash object swfobject

1. object + embed 传统的方法
优点：浏览器兼容性好，是 Macromedia 一直以来的官方方法
缺点：
a.embed 标签是不符合 W3C 的规范的，无法通过验证。当然，如果你不在乎什么规范不规范，另当别论。
b.微软由于种种原因，在 sp2 后限制了 IE 的 ActiveX 的使用模式，就是在页面中的 ActiveX 有一个虚框，需要用户点击一次才能正常交互。Flash是作为一个 ActiveX 嵌入到网页中的，所以它也会受牵连，只有通过 JS 嵌入 Flash 才能解决这个问题。
c.没有 Flash 版本检测，如果版本浏览器的flash插件版本不够，或者不能正常显示你的 swf 文件，或者会弹出一个 ActiveX 的确认安装的框。

<object id="forfun" classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" width="400" height="300"
    codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0">
    <param name="movie" value="/seufld/seufld/flash/focus2.swf">
    <param name="quality" value="high">
    <param name="bgcolor" value="#F0F0F0">
    <param name="menu" value="false">
    <param name="wmode" value="opaque"><!--Window|Opaque|Transparent-->
    <param name="FlashVars" value="">
    <param name="allowScriptAccess" value="sameDomain">
    <embed id="forfunex" src="/seufld/seufld/flash/focus2.swf"
        width="400"
        height="300"
        align="middle"
        quality="high"
        bgcolor="#f0fff8"
        menu="false"<!--添加后,ff下才正常-->
        play="true"
        loop="false"
        FlashVars=""
        allowScriptAccess="sameDomain"
        type="application/x-shockwave-flash"
        pluginspage="http://www.adobe.com/go/getflashplayer">
    </embed>
</object>

2. 单object
这种方法的名字叫做 Flash satay，最早是2002年由 Drew McLellan 发表在 A List Apart 上，后来又经过了几次完善：

<object type="application/x-shockwave-flash" data="c.swf?path=movie.swf"
width="400" height="300">
<param name="movie" value="c.swf?path=movie.swf" />
<img src="http://xuguangzhi2003.blog.163.com/blog/noflash.gif" width="200" height="100" alt="" />
</object>

优点：这方法没有embed，可以通过验证，浏览器兼容性也不错
缺点：
a.需要一个 holder swf 来加载你的目标 swf 以保证 IE 中的 stream 能力，如果你需要通过 flashvars 来传参，或者和页面的 JS 交互，会很麻烦。
b.ActiveX的虚框问题。
c.没有版本检测。
d.还是有少数用户代理（比如一些版本的 safari 和一些屏幕阅读器）不认这种方式，有 bug。

3. 双object

<object id="exercises" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="214" height="144">
    <param name="movie" value="${contextPath}/flex/photo.swf" />
    <param name="wmode" value="window" />
    <param name="flashvars" value=""/>
    <!--[if !IE]><!-->
    <object id="exercisesEx" type="application/x-shockwave-flash"
        data="${contextPath}/flex/photo.swf" width="214" height="144">
        <param name="flashvars" value=""/>
    <!--<![endif]-->
        <!--[if gte IE 6]>
        <![endif]-->
        <!--[if !IE]><!-->
        <!--<![endif]-->
        <a href="http://www.adobe.com/go/getflashplayer">
            <img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" />
        </a>
    <!--[if !IE]><!-->
    </object>
    <!--<![endif]-->
</object>

5. swfobject

6. 单embed显示 ie7和ff3下都能正常显示

<embed allowscriptaccess="never" allownetworking="internal" invokeurls="false" src="http://chabudai.sakura.ne.jp/blogparts/honehoneclock/honehone_clock_tr.swf" 
pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" quality="high" autostart="0" wmode="transparent" width="100%" 
height="300" align="middle">
