【问题描述】：

我正在尝试根据该数组中一个对象的数值对该数组进行排序。所以我当前的数组是：

{opp_id: 123, latitude: "40.0467921", longitude: "-76.29504939999998", distance: 4.326332246421182}
{opp_id: 115, latitude: "39.9492628", longitude: "-76.69909960000001", distance: 24.81327544469476}
{opp_id: 66, latitude: "40.0467921", longitude: "-76.29504939999998", distance: 4.326332246421182}
{opp_id: 64, latitude: "37.7863453", longitude: "-122.44204609999997", distance: 2464.2610167173516}

我想要做的是然后根据“距离”对象按从最小到最大的数字对这个数组进行排序。有没有 Javascript 函数可以做到这一点？

使用sort，如下所示。

x=[{opp_id: 123, latitude: "40.0467921", longitude: "-76.29504939999998", distance: 4.326332246421182},
{opp_id: 115, latitude: "39.9492628", longitude: "-76.69909960000001", distance: 24.81327544469476},
{opp_id: 66, latitude: "40.0467921", longitude: "-76.29504939999998", distance: 4.326332246421182},
{opp_id: 64, latitude: "37.7863453", longitude: "-122.44204609999997", distance: 2464.2610167173516}]

console.log(x.sort((a,b)=>a.distance-b.distance))
