    //  获取或设置当前页面的 jQuery EasyUI 主题皮肤包；该函数定义如下参数：
    //      isTop: 可选参数；表示是否从当前窗口的顶级页面逐级向下依次设置所有页面包括iframe在内的皮肤包名称；
    //      themeName: 可选参数；表示被设置的皮肤包名称；
    //      callback: 可选参数；表示在设置完皮肤包名称后要执行的回调函数；该回调函数执行时依次定义如下参数：
    //          newTheme: 表示更改后的主题皮肤；
    //          oldTheme: 表示更改前的主题皮肤；
    //          上面两个参数 oldTheme、newTheme 都是一个格式如 { id, name, path } 的 JSON-Object，其可能的值参考 $.easyui.theme.dataSource 。
    //      thisArg: 可选参数；表示 callback 回调函数执行中的 this 引用；
    //  备注：如果该方法未传入任何参数；则获取当前页面的 jQuery EasyUI 主题皮肤名称并返回；
