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;
