1. 微信小程序地图撒点

1.1 说明

首先使用微信小程序自带标签，并且设置好宽高让地图显示，用longitude和latitude表示中心点。
（1）show-location 显示带有方向的当前定位点,本项目不需要不添加。
（2）scale=“4” 缩放比例，缩放级别，取值范围为3-20。
（3）markers的图标想要圆的可直接让设计做成圆形，用iconPath添加。

1.2. wxml代码

<view class="map-layout">
  <map class="map-contianer" id="myMap" markers="{{markers}}" longitude="{{locObj.longitude}}" latitude="{{locObj.latitude}}" scale='16' show-location="true">
  </map>
</view>

1.3. wxss代码

.map-layout {
  position: relative;
  height: 100vh;
}
.map-contianer{
  width:100%;
  height:100%;
}

1.4. js代码

var app = getApp()
const qqmapsdk = app.globalData.qqmapsdk
Page({

  /**
   * 页面的初始数据
   */
  data: {
 //地图相关
 markers: '', //设置markers属性和地图位置poi，将结果在地图展示
 locObj: {
   latitude: '',
   longitude: '',
   address: ''
 },
  },

  /**
   * 生命周期函数--监听页面加载
   */
  onLoad(options) {
    var that = this;
    that.getAddress()
  },
//=======================地图相关===================
getAddress(e) {
  var that = this;
  qqmapsdk.reverseGeocoder({
    success: function (res) {
      that.data.locObj.address = res.result.address
      that.setData({
        locObj: that.data.locObj
      })
      var res = res.result;
      var markerArr = [];
      var curLat=res.location.lat
      var curLng=res.location.lng
      // 36.66645
      // 117.07641
      markerArr.push({ 
        title: res.address,
        id: 0,
        latitude: curLat,
        longitude: curLng,
        iconPath: '/icon_map_addr_hospital.png', 
        width: 28,
        height: 32,
      },{ 
        title: res.address,
        id: 1,
        latitude: (curLat-0.0009),
        longitude:(curLng-0.0007),
        iconPath: '/icon_map_addr_house.png', 
        width: 32,
        height: 32,
      },{ 
        title: res.address,
        id: 2,
        latitude: (curLat+0.0009),
        longitude:(curLng+0.0003),
        iconPath: '/icon_map_addr_wc.png', 
        width: 28,
        height: 32,
      },{ 
        title: res.address,
        id: 3,
        latitude: (curLat-0.0009),
        longitude:(curLng+0.0011),
        iconPath: '/icon_map_addr_wc.png', 
        width: 28,
        height: 32,
      },{ 
        title: res.address,
        id: 4,
        latitude: (curLat+0.0004),
        longitude:(curLng+0.0011),
        iconPath: '/icon_map_addr_house.png', 
        width: 28,
        height: 32,
      },{ 
        title: res.address,
        id: 5,
        latitude: (curLat+0.0004),
        longitude:(curLng-0.0011),
        iconPath: '/icon_map_addr_hospital.png', 
        width: 28,
        height: 32,
      });
      that.data.locObj.latitude = res.location.lat
      that.data.locObj.longitude = res.location.lng
      that.setData({ // 设置markers属性和地图位置poi，将结果在地图展示
        markers: markerArr,
        locObj: that.data.locObj
      });
    },
    fail: function (error) {
      console.error(error);
    },
    complete: function (res) {
      console.log(res);
    }
  })
},
