SWFObject是一个用于在HTML中方面插入Adobe Flash媒体资源（*.swf文件）的独立、敏捷的JavaScript模块。该模块中的JavaScript脚本能够自动检测PC、Mac机器上各种 主流浏览器对Flash插件的支持情况。它使得插入Flash媒体资源尽量简捷、安全。而且它是非常符合搜索引擎优化的原则的。此外，它能够避免您的 HTML、XHTML中出现object、embed等非标准标签，从而符合更加标准。
（即：通过text/html应答页面， 而非application/xhtml+xml）
SwfObject中文翻译(很详细的):http://www.awflasher.com/flash/articles/swfobj.htm
