我想实现列表显示距离，现在出现的问题是：必须上拉加载后才会显示，页onload 不显示。请大神指教！！
异步问题 代码不是按顺序执行的
let list = [{id: 1},{id: 2}]// 模拟获取经纬度function mapService() {return new Promise((relove, reject) => {setTimeout(() => {relove({jd: 1,wd: 1})})})}async function onLoad() {for(let i = 0; i < list.length; i += 1) {let {jd, wd} = await mapService();list[i].jd = jd;list[i].wd = wd;}console.log(list)}onLoad();
