微信红包曾经引爆过一系列的营销热潮，相信大家对于这种红包形式并不陌生，这里本着娱乐至上的精神用React简单地实现了拆红包的动画效果，供大家一起交流学习

用CSS3绘制红包

.redpack {  height: 450px;  background: #A5423A;  width: 300px;  left: 0;  top: 0;  border-radius: 10px;  margin: 0 auto;}.topcontent {    height: 300px;    border: 1px solid #BD503A;    background-color: #BD503A;    border-radius: 10px 10px 50% 50% / 10px 10px 15% 15%;    box-shadow: 0px 4px 0px -1px rgba(0,0,0,0.2);}#redpack-open {    width: 100px;    height: 100px;    border: 1px solid #FFA73A;    background-color: #FFA73A;    border-radius: 50%;    color: #fff;    font-size: 20px;    display: inline-block;    margin-top: -50px;    box-shadow: 0px 4px 0px 0px rgba(0, 0, 0, 0.2);}

<div class='redpack'>  <!--  红包的顶部盖子 -->  <div class="topcontent"></div>  <!-- 拆红包的按钮 -->  <div id="redpack-open"></div></div>

效果如图：

用React来区分不同的状态的转换

用React.js来实现的话，主要通过判断state来控制红包现在是等待拆开还是已经拆开过，具体的代码如下

import React from 'react';class ReadPacket extends React.Component {    constructor(props) {        super(props);        this.state = {animation: false,status: 0  // 0: 等待拆开 1: 拆开后        };    }    render() {        var bonus = this.props.thanks ? 0 : parseFloat(this.props.surveyInfo.bonus);        if(this.state.status == 0) {return (    <div className='redpack-container' id='redpack-container'>        <div className='redpack'><div className='topcontent'>    <div id='redpack-opened'>      <div className='redpack-avatar'>        <img src='http://placehold.it/80x80' alt='头像' width='80' height='80'/>      </div>    </div>    <h2 style={{marginTop: 80, color: 'white'}}>奖励</h2>    <span className='redpack-text'>点击下方按钮领取红包</span>    <div className='redpack-description white-text'>恭喜发财 大吉大利</div></div><div id='redpack-open' className={this.state.animation ? 'rotate' : ''}     onClick={this.openRedPacket.bind(this)}>    <span>拆红包</span></div>        </div>    </div>);        } else if (bonus == 0) {// 谢谢参与return (    <div className='redpack-container' id='redpack-container'>        <div className='redpack'><div className='topcontent-open'>    <div className='redpack-avatar'>        <span id='close'></span>    </div>    <h1 style={{marginTop: 180, color: 'white'}}> 谢谢参与 </h1>    <span className='redpack-text'>多多参与的奖励的机会更多哦</span>    <br/>    <a onClick={this._toWallet.bind(this)}       style={{cursor:'pointer',textDecoration: 'underline', color: 'white'}}>        去我的账户查看    </a></div><div id='redpack-opened'>  <div className='redpack-avatar'>    <img src='http://placehold.it/80x80' alt='头像' width='80' height='80'/>  </div></div>        </div>    </div>);        } else {// 显示奖励金额return (    <div className='redpack-container' id='redpack-container'>        <div className='redpack'><div className='topcontent-open'>    <div className='redpack-avatar'>        <span id='close'></span>    </div>    <h1 className='white-text' style={{marginTop: 180}}> {bonus.toFixed(2)} </h1>    <span className='redpack-text'>奖励积分已经存入您的账户</span>    <a className='btn-flat white-text' onClick={this._toWallet.bind(this)}       style={{textDecoration: 'underline'}}>        去我的账户查看积分    </a></div><div id='redpack-opened'>  <div className='redpack-avatar'>    <img src='http://placehold.it/80x80' alt='头像' width='80' height='80'/>  </div></div>        </div>    </div>);        }    }    stopAnimation() {        this.setState({animation: false});    }    showResult() {        this.setState({status: 1});    }    openRedPacket() {        this.setState({animation: true});        setTimeout(this.stopAnimation.bind(this), 3000);        setTimeout(this.showResult.bind(this), 4000);    }    _toWallet() {      // 跳转到钱包      window.location.hash = '/wallet';    }}export default ReadPacket;
