.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);

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;
