const that = this;
that.data.clinic.forEach((element) => {
var loc = element.province + element.city + element.name;
const timer = setTimeout(()=>{
clearTimeout(timer);
element.latitude = '2222222'
element.longitude = '33333333'
},1000);
});
that.setData({
clinic: that.data.clinic
});
console.log(that.data.clinic);
这么统一赋值即可
赋值方法错了吧，setData貌似要从data层往里找，你这直接过滤掉clinic了
