reacttransitiongroup配合css透明度变化，实现页面顺滑跳转。

效果：

 

 

1.安装依赖包 react-transition-group

2.引入组件

import { TransitionGroup, CSSTransition } from 'react-transition-group';

3.指定前进和后退的标识，和切换期间时长

const ANIMATION_MAP = {
  PUSH: 'forward',
  POP: 'back',
};
const _timeout = 1000;

ANIMATION_MAP[history.action]为指定CSSTransition的样式

外加css代码进行透明度调整切换

//动态透明度变动效果
.animate-route {
  animation-duration: 1s;
  animation-fill-mode: both;
  animation-name: fadeRoute;
}
@keyframes fadeRoute {
  from {
    opacity: 0;
  }

  to {
    opacity: 1;
  }
}

将animate-route放在页面切换的父元素上即可
