从数据库中取得数据后，根据数据库中的属性让icon显示不同的颜色，求问：怎么可以在点击icon时，改变它的颜色？或者这个代码可以怎么修改来得到我想要的效果
<view wx:for="{{seatnum}}" wx:key="objectId"> <view> <icon data-index="{{index}}" type="success" color="{{item.status == '0' ? 'green' : item.status == '1' ? 'red' : item.status == '2' ? 'orange' : 'grey'}}" bindtap="click" /> </view> </view> click (e) { let index = parseInt(e.currentTarget.dataset.index); this.setData({ [`seatnum[${index}].status`]: "你要的颜色？" }); }js里面click函数里，this.setData改变item.status
