本文实例讲述了react使用CSS实现react动画功能。分享给大家供大家参考,具体如下:
react动画:
import React, { Component } from 'react'; class Boss extends Component { constructor(props) { super(props); this.state = { isShow:true } this.toTogger=this.toTogger.bind(this) } render() { return ( <div> <div className={this.state.isShow?'show':'hide'}>大BOSS--孙悟空</div> <div><button onClick={this.toTogger}>召唤</button></div> </div> ); } toTogger() { this.setState({ isShow:this.state.isShow?false:true }) } } export default Boss;
css:
.hide{opacity: 1;transition: all 1.5s ease-in;} .show{opacity: 0;transition: all 1.5s ease-in;}
keyframes动画:
.hide{animation: hide-item 2s ease-in forwards;} .show{animation: show-item 2s ease-in forwards;} @keyframes hide-item{ 0%{ opacity: 0; color: red; } 50%{ opacity: 0.5; color: saddlebrown; } 100%{ opacity: 1; color: yellow; } } @keyframes show-item{ 0%{ opacity: 1; color:green; } 50%{ opacity: 0.5; color:greenyellow; } 100%{ opacity: 0; color: yellow; } }
react-transition-group动画库:
import {CSSTransition} from 'react-transition-group'; render() { return ( <div> <CSSTransition in={this.state.isShow} timeout={2000} classNames="boss-text" unmountOnExit > {/* <div className={this.state.isShow?'show':'hide'}>大BOSS--孙悟空</div> *
