自flex4出来后问题不断，以前很多类被摒弃了。导致现在很多方法都要替换。
?
最近在action里面修改CSS发现用StyleManager的时候居然提示：
?
自 4.0 以来已弃用。?请使用 IStyleManager2.getStyleDeclaration on a style manager instance
获取存储指定 CSS 选择器规则的 CSSStyleDeclaration 对象。
?
超级无语，搜索了半天也无结果，10年底的文章里面都还是沿用的StyleManager，
?
只有做个实例试验下了：

搞笑的是这样写直接提示getStyleDeclarations可能未定义。什么情况？？？
编辑器直接给出来的居然未定义，而且点到类里也有。没办法，继续用StyleManager
至少能正常运行- -~~~

应该完整写入：mx.styles.IStyleManager2.getStyleDeclarations
-
