The Api option to control CSS transition of the popup, is popup-transition , not pop-transition.
关于Popup组件的动画的API 应该为 popup-transition，而不是pop-transition
The default value 'popup-fade' has not corresponding style definition, you have to implement it yourself
使用了正确的API后也没有效果，因为这段css在mint-ui中并没有体现，而是需要自己手动加上css样式。
