简单实现小程序地图
官方文档:https://developers.weixin.qq.com/miniprogram/dev/component/map.html
map.wxml:
<view> <map id="map" longitude="{{获取的坐标}}" latitude="{{获取的坐标}}" scale="14" show-location style="width: 100%; height: 300px;"> </map> </view>
map.js:
Page({ data: { markers: [{ iconPath: "/resources/others.png", id: 0, latitude: 23.099994, longitude: 113.324520, width: 50, height: 50 }], polyline: [{ points: [{ longitude: 113.3245211, latitude: 23.10229 }, { longitude: 113.324520, latitude: 23.21229 }], color:"#FF0000DD", width: 2, dottedLine: true }], controls: [{ id: 1, iconPath: '/resources/location.png', position: { left: 0, top: 300 - 50, width: 50, height: 50 }, clickable: true }] }, regionchange(e) { console.log(e.type) }, markertap(e) { console.log(e.markerId) }, controltap(e) { console.log(e.controlId) } })
由于map应用需要获取个人信息,需要设置信息
“permission”:{ “scope.userLocation”:{ “desc”:“你的位置将用于小程序地图展示” //描述信息 } }
在页面加载时,调用获取地理位置API
wx.getLocation({ type: 'wgs84', success (res) { const latitude = res.latitude const longitude = res.longitude const speed = res.speed const accuracy = res.accuracy } })
