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。

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。
