yii中的三级省市联动

注意事项：

如果是在admin这个modules下的CRUD，则'url'=>Yii::app()->createUrl('admin/TblMembers/dynamicCity')这样的形式。

如果是在前台，则为：'url'=>Yii::app()->createUrl('TblMembers/dynamicCity')

另外：'url'=>Yii::app()->createUrl('admin/TblMembers/dynamicCity')这里的TblMembers一定要区分大小写，否则会出错。这里最好去复制模型的名称，以防出错。

访问不了，有时会是控制器下的accessRules没有设置好。

代码如下：

控制器
