react 使用map 的时候提示 没有返回值

复制提示
因为map 的函数体里 用了if判断，在if块之外return 一个值就可以了
<div className="service-entry">
{!!services && services.map((item,index) => {
if(item.name === '洗衣机'){
return (
<div key={index} className='wanshing-entry busy' onClick={this.ShowFeeModel}>
<div className="state-icon"></div>
<div className="seal">
<span className="seal-time">{item.minTime/60}分钟 /</span>
<span className="money-icon">￥</span>
<span className="seal-money">{item.price}</span>
</div>
<div className="entry-text">我要洗衣</div>
</div>
);
}else if(item.name === '烘干机'){
return(
<div key={index} className="drying-entry maintenance" onClick={this.ToDry}>
<div className="state-icon"></div>
<div className="seal">
<span className="seal-time">{item.minTime/60}分钟 /</span>
<span className="money-icon">￥</span>
<span className="seal-money">{item.price}</span>
</div>
<div className="entry-text">我要烘干</div>
</div>
// <div className="refer-time">参考剩余时间：20分钟</div>
);
}
return null;
