AS：Flash AS3中获取浏览器信息及URL相关参数（并非swf url地址）

好久没来这里了，最近发现网络上对此类信息的封装少的可怜，没有一个是比较完整的，今天又是周未，不敲点代码手痒痒的，^_^，所以本人手贱借此时发布一篇是关于 AS3中获取浏览器信息及URL相关参数的WebUtils类，欢迎大家拍砖以使此类更丰富一些！

先来看看效果，因本机没装多个浏览器测试，所以只截了几个浏览器的获取的结果

IE：

360，内核是IE核心，所以效果跟IE基本一样

FF,即FireFox（火狐中国版）

 

以下是Test.as测试类：

汗，研究了一会，没有看到有Flash或AS3类的分类，不知发布到哪里了，随便选了一个Flex，哈哈
