react使用CSS实现react动画功能示例

这篇文章主要介绍了react使用CSS实现react动画功能,结合实例形式分析了react使用CSS实现react动画功能具体步骤与实现方法,需要的朋友可以参考下

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 (  大BOSS--孙悟空
 ); } 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 (   {/* 大BOSS--孙悟空
 */} 大BOSS--孙悟空
 ); }

 .boss-text-enter{opacity: 0;} .boss-text-enter-active{opacity: 1;transition: opacity 2000ms;} .boss-text-enter-done{opacity: 1;} .boss-text-exit{opacity: 1;} .boss-text-exit-active{opacity: 0;transition: opacity 2000ms;} .boss-text-exit-done{opacity: 0;}

多DOM动画：

 import React, { Component, Fragment } from 'react'; import List from './List.js'; import axios from 'axios'; import Boss from './Boss'; import {CSSTransition,TransitionGroup} from 'react-transition-group' class Test extends Component { constructor(props) { super(props); this.state={ inputValue:'aaa', list:[], } // this.add=this.add.bind(this); } addList() { this.setState({ list:[...this.state.list,this.state.inputValue], inputValue:'' }) } change(e) { this.setState({ // inputValue:e.target.value inputValue:this.input.value }) } delete(i) { // console.log(i); const list = this.state.list; list.splice(i,1); this.setState({ list:list }) } componentDidMount() { // console.log('componentDidMount'); axios.get('https://www.easy-mock.com/mock/5e1d3d1564a3c20d7f366f91/ReactDemo1/App') .then((res)=>{ console.log('获取数据'+JSON.stringify(res)); this.setState({ list:res.data.data }); }) .catch((error)=>{console.log('获取数据失败'+error)}); } render() { console.log('3-render'); return (   {this.input=input}} value={this.state.inputValue} onChange={this.change.bind(this)}/> 
  { this.state.list.map((v,i)=>{ return(   ); }) } 
 ); } } export default Test;

希望本文所述对大家react程序设计有所帮助。
