allMarkers效果图

 

废话少说直接上马（最后是我遇到的问题）

cover-view是气泡弹窗，可以自定义弹窗，要配合js：customCallout，如果是非自定义的话：callout（可以修改颜色、边框宽度、圆角、边距等）有些属性我没加，还是看官方文档（虽然写的。。）

<!--index.wxml-->
<view class="page-section page-section-gap">
  <map id="myMap" style="width: 100%; height: 450px;" latitude="{{latitude}}" longitude="{{longitude}}" bindmarkertap="markertap" bindcallouttap="callouttap" bindlabeltap="labeltap" markers="{{markers}}" scale="16" polyline="{{polyline}}">
    <cover-view slot="callout">
      <block wx:for="{{customCalloutMarkerIds}}" wx:key="*this">
        <cover-view class="customCallout" marker-id="{{item}}">
          <!-- <cover-image class="icon" src="../img/point.png"></cover-image> -->
          <cover-view class="content">
            <view style="background-color: #fff;">
              <view>设备名称</view>
              <view>设备名称</view>
              <view>设备名称</view>
            </view>
          </cover-view>
        </cover-view>
      </block>
    </cover-view>
  </map>
  <button bindtap="addMarker" class="page-body-button" type="primary">添加marker</button>
</view>

字段说明：

allMarkers：模拟位置点

markers：地图显示位置点

polyline：地图点连线位置点

mapCtx：初始化地图

 customCallout：气泡自定义使用（建议使用方法）

callout：气泡简易使用

const normalCallout = {
  id: 1,
  latitude: 23.098994,
  longitude: 113.322520,
  iconPath: '../img/point.png',
  callout: {
    content: '文本内容',
    color: '#ff0000',
    fontSize: 14,
    borderWidth: 2,
    borderRadius: 10,
    borderColor: '#000000',
    bgColor: '#fff',
    padding: 5,
    display: 'ALWAYS',
    textAlign: 'center'
  },
}

const customCallout1 = {
  id: 2,
  latitude: 23.097994,
  longitude: 113.323520,
  iconPath: '../img/point.png',
  callout: {
    content: '文本内容',
    color: '#ff0000',
    fontSize: 14,
    borderWidth: 2,
    borderRadius: 10,
    borderColor: '#000000',
    bgColor: '#fff',
    padding: 5,
    display: 'ALWAYS',
    textAlign: 'center'
  },
}

const customCallout2 = {
  id: 3,
  latitude: 23.096994,
  longitude: 113.324520,
  iconPath: '../img/point.png',
  customCallout: {
    anchorY: 10,
    anchorX: 0,
    display: 'ALWAYS',
  },
}

const customCallout3 = {
  id: 4,
  latitude: 23.095994,
  longitude: 113.325520,
  iconPath: '../img/point.png',
  customCallout: {
    anchorY: 0,
    anchorX: 20,
    display: 'ALWAYS',
  },
}

const allMarkers = [normalCallout, customCallout1, customCallout2, customCallout3]

Component({
  data: {
    mapCtx: '',
    latitude: 23.098994,
    longitude: 113.322520,
    customCalloutMarkerIds: '',
    markers: [],
    polyline: []
  },
  onReady: function (e) {
    // 使用 wx.createMapContext 获取 map 上下文
    this.mapCtx = wx.createMapContext('myMap')

  },
  methods: {
    addMarker() {
      var list = []
      var that = this
      for (const i in allMarkers) {
        var point = {
          latitude: allMarkers[i].latitude,
          longitude: allMarkers[i].longitude
        }
        list.push(point)
      }
      console.log(this.data.polyline.points)
      this.setData({
        polyline:[{
          points: list,
          color: '#58c16c',
          width: 6,
          borderColor: '#2f693c',
          borderWidth: 1,
          arrowLine: true
        }],
        markers: allMarkers,
        customCalloutMarkerIds: [2, 3, 4],
      })
    },

  },
})

xml和js直接复制就可以运行了没有其他配置

所遇到问题：

1.初始化时我在data直接给markers和polyline赋值了，导致不能显示气泡，解决是加了一个按钮等map初始化结束在添加点就正常了

2.marker-id必须是number

3.我没写，但是我感觉自定义气泡是可以加点击事件的
