在as3中Embed(绑定)flash动画元素

ref:http://zszen.tbcheap.com/wordpress/life/?p=283

你需要使用loader类的loadBytes方法将这个二进制流转换成显示类
如果你需要控制embed进来的元件, 那么你需要侦听loader.contentLoadInfo的Event.Complete事件
当完成装载后你既的内部embed元件就可以随心所欲的玩了
此时的loader.content即为MainTimeline类, 这时你直接写loader.content.txt严格的话会报错, 你可以使用弱引用 loader.content["txt"] 然后声明个临时变量, 在cs5里面还能给个代码功能提醒

附上我的demo附件作为例子看吧 (本地就不传了, 去论坛下吧)link

另外附上测试的embed各种格式的父类关系
jpg/gif/png:
Main_EMBED
mx.core::BitmapAsset
mx.core::FlexBitmap

swf文件:
Main_EMBED
mx.core::ByteArrayAsset

mp3声音类:
Main_EMBED
mx.core::SoundAsset

txt文本:
不支持
does not have a recognized extension, and a mimeType was not provided

xml文档:
不知道为什么这么报错
expecting semicolon before id

pdf文件同swf
zip压缩包同swf

另外font应该也是可以镶入的, 没测

官方文档里面提到了到底支持绑定什么类型的文件:http://livedocs.adobe.com/flex/3 … ontent=embed_4.html

收集到的各类文件镶入方法
