- 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) {}})
