【ReactCSSTransitionGroup】
ReactCSSTransitionGroup is a high-level API based on ReactTransitionGroup and is an easy way to perform CSS transitions and animations when a React component enters or leaves the DOM.
import ReactCSSTransitionGroup from ‘react-addons-css-transition-group‘; // ES6var ReactCSSTransitionGroup = require(‘react-addons-css-transition-group‘); // ES5 with npm
<ReactCSSTransitionGroup ?????????transitionName="example" ?????????transitionEnterTimeout={500} ?????????transitionLeaveTimeout={300}> ?????????{items} ???????</ReactCSSTransitionGroup> You must provide the key attribute for all children of ReactCSSTransitionGroup, even when only rendering a single item. This is how React will determine which children have entered, left, or stayed.
