关于微信小程序:微信小程序用腾讯地图计算距离

1. 首先引入地图

var QQMapWX = require('../../libs/qqmap/qqmap-wx-jssdk1.2/qqmap-wx-jssdk');var qqmapsdk;qqmapsdk = new QQMapWX({  key: '填申请的key'});

从接口取得列表list后，往目的地数组push值

let destinations = [];for (var i = 0; i < list.length; i++) {  destinations.push({    location: {      lat: list[i].lat,      lng: list[i].lng    }  })}

而后应用地图接口来计算间隔

let self = this;qqmapsdk.calculateDistance({    from: {      latitude: userLocation.lat,      longitude: userLocation.lng    }, // 从以后用户的定位算    to: destinations,    success: (res) => {      let elements = res.result.elements;      let box = [];      for (let x = 0; x < elements.length; x++) {        let distance;        if (elements[x].distance >= 1000) {          distance = (elements[x].distance / 1000) + 'km';        } else {          distance = parseInt(elements[x].distance) + 'm';        }        box.push({          id: list[x].id,           ... // 其余属性（略）          distance: distance        })      };      self.setData({        list: box      })    },    fail: function (failRes) {},    complete: function (completeRes) {} })
