Flex loaderInfo swf模块获取url传递的参数

此方法是在被加载的模块中使用loaderInfo属性返回一个 LoaderInfo 对象，其中包含加载此显示对象所属的文件的相关信息。loaderInfo 属性仅为 SWF 文件的根显示对象或已加载的位图（而不是使用 ActionScript 绘制的位图）定义。例如要查找与包含名为 myDisplayObject 的显示对象的 SWF 文件相关的 loaderInfo 对象，请使用 myDisplayObject.root.loaderInfo。

大的 SWF 文件可以通过调用 this.root.loaderInfo.addEventListener(Event.COMPLETE, func) 来监控其下载。
