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 (
<p classname='redpack-container' id='redpack-container'>
<p classname='redpack'>
<p classname='topcontent'>
<p id='redpack-opened'>
<p classname='redpack-avatar'>
<img src='http://placehold.it/80x80' alt='头像' width='80' height='80'/>
</p>
</p>
<h2 style={{margintop: 80, color: 'white'}}>奖励</h2>
<span classname='redpack-text'>点击下方按钮领取红包</span>
<p classname='redpack-description white-text'>恭喜发财 大吉大利</p>
</p>
<p id='redpack-open' classname={this.state.animation ? 'rotate' : ''}
onclick={this.openredpacket.bind(this)}
>
<span>拆红包</span>
</p>
</p>
</p>
);
} else if (bonus == 0) {
// 谢谢参与
return (
<p classname='redpack-container' id='redpack-container'>
<p classname='redpack'>
<p classname='topcontent-open'>
<p classname='redpack-avatar'>
<span id='close'></span>
</p>
<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'}}>

</p>
<p id='redpack-opened'>
<p classname='redpack-avatar'>
<img src='http://placehold.it/80x80' alt='头像' width='80' height='80'/>
</p>
</p>
</p>
</p>
);
} else {
// 显示奖励金额
return (
<p classname='redpack-container' id='redpack-container'>
<p classname='redpack'>
<p classname='topcontent-open'>
<p classname='redpack-avatar'>
<span id='close'></span>
</p>
<h1 classname='white-text' style={{margintop: 180}}> {bonus.tofixed(2)} </h1>

</p>
</p>
</p>
);
}
}
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
