微信紅包曾經引爆過一系列的營銷熱潮，相信大家對于這種紅包形式并不陌生，這里本著娛樂至上的精神用React簡單地實現了拆紅包的動畫效果，供大家一起交流學習
用CSS3繪制紅包
.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'> <!-- 紅包的頂部蓋子 --> <div class="topcontent"></div> <!-- 拆紅包的按鈕 --> <div id="redpack-open"></div> </div>
效果如圖：
用React來區分不同的狀態的轉換
用React.js來實現的話，主要通過判斷state來控制紅包現在是等待拆開還是已經拆開過，具體的代碼如下
import React from 'react';
class ReadPacket extends React.Component {
constructor(props) {
super(props);
this.state = {
animation: false,
status: 0 // 0: 等待拆開 1: 拆開后
};
}
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='頭像' width='80' height='80'/>
</div>
</div>
<h2 style={{marginTop: 80, color: 'white'}}>獎勵</h2>
<span className='redpack-text'>點擊下方按鈕領取紅包</span>
<div className='redpack-description white-text'>恭喜發財 大吉大利</div>
</div>
<div id='redpack-open' className={this.state.animation ? 'rotate' : ''}
onClick={this.openRedPacket.bind(this)}
>
<span>拆紅包</span>
</div>
</div>
</div>
);
} else if (bonus == 0) {
// 謝謝參與
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'}}> 謝謝參與 </h1>
<span className='redpack-text'>多多參與的獎勵的機會更多哦</span>
<br/>
<a onClick={this._toWallet.bind(this)}
style={{cursor:'pointer',textDecoration: 'underline', color: 'white'}}>

</a>
</div>
<div id='redpack-opened'>
<div className='redpack-avatar'>
<img src='http://placehold.it/80x80' alt='頭像' width='80' height='80'/>
</div>
</div>
</div>
</div>
);
} else {
// 顯示獎勵金額
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'>獎勵積分已經存入您的賬戶</span>
<a className='btn-flat white-text' onClick={this._toWallet.bind(this)}
style={{textDecoration: 'underline'}}>
去我的賬戶查看積分
</a>
</div>
<div id='redpack-opened'>
<div className='redpack-avatar'>
<img src='http://placehold.it/80x80' alt='頭像' 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() {
// 跳轉到錢包
window.location.hash = '/wallet';
}
}
export default ReadPacket;
