 Simple small program to achieve Map

　　The official document: https://developers.weixin.qq.com/miniprogram/dev/component/map.html

　　map.wxml:

< View > 
    < Map ID = "Map" longitude = "{{acquired coordinate}}" Latitude = "{{acquired coordinate}}" Scale = "14" Show-LOCATION style = "width: 100%; height: 300px by; " > 
</ 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)
  }
})

　As the map applications that require access to personal information, the information needs to be set

"Permission": { 
     "scope.userLocation": { 
         "desc": "Your location will be used applets map to show" // descriptive information 
    }     
}

 When the page loads, call to get the Geolocation API

wx.getLocation({
 type: 'wgs84',
 success (res) {
   const latitude = res.latitude
   const longitude = res.longitude
   const speed = res.speed
   const accuracy = res.accuracy
 }
})
