高德地图撒点组件

一、引入amap地图库 - public/index.html

<script type="text/javascript">
    window._AMapSecurityConfig = {
      securityJsCode: '地图密钥' 
    }
  </script>
  <script
    type="text/javascript"
    src="https://webapi.amap.com/maps?v=1.4.8&key=111111111111111111111111"
  ></script>

二、组件 - DzvScatterMap

<template>
  <div class="container-box">
    <div id="container"></div>
  </div>
</template>
<script>
import { containerType, getLocation } from '@/utils/alipay'
import locationImg from '@/assets/images/location.png'

const { AMap } = window

    list: {
      type: Array,
      default: () => []
    },
    // 样式列表
    styles: {
      type: Array,
      default: () => []
    }
  },
  data() {

      mass: null,
      styleList: []
    }
  },
  watch: {
    lngLat: function(value) {
      if (value && value.length > 0) {
        this.initAMap()
      }
    },
    list: {
      deep: true,
      handler: function(newVal) {
        if (this.map) {

      }
    },
    styles: {

          anchor: new AMap.Pixel(6, 6),
          size: new AMap.Size(iconSize, 56),
          zIndex: 3
        }))
      }
    }
  },
  created() {},

        resizeEnable: true,
        center: [113.67621, 34.74499], // 默认中心点坐标
        viewMode: '2D' // 使用2D视图,使用3D在amap2.0中会旋转
      })
      this.markerMyPosition(this.lngLat)
    },
    // 标记自己的位置
    markerMyPosition(lngLat) {
      if (lngLat && lngLat.length > 0) {
        if (this.locationMarker) {
          this.map.remove(this.locationMarker)
        }

        this.locationMarker = new AMap.Marker({

          position: new AMap.LngLat(lngLat[0], lngLat[1]),
          zoom: 13,
          content: `

        })
        if (this.map) {
          this.map.add(this.locationMarker) // 添加位置marker
          this.map.setCenter(lngLat) // 设置中心
          this.map.setZoom(defaultZoom) // 重置缩放
          this.panBy() // 设置地图平移量，将marker移到中心
        }
      }
      // 地图加载完成后，进行撒点
      this.asyncMarker()
    },
    // 地图的平移
    panBy() {
      const refList = document.getElementById('refList')

        this.mass.on('click', this.markerClick)
        this.mass.setMap(this.map)
        this.$forceUpdate()
      }
    },
    // 类型和全部定位数据修改的时候进行延迟撒点，展示列表中的loading效果
    asyncMarker() {

      setTimeout(() => {
        const { allPoints, currentType } = _this
        _this.getMarkerList(allPoints, currentType)
      }, 5)
    },
    // 点击事件
    markerClick(e) {
      // const curentPoint = e.target.getExtData() || {}

</script>
<style lang="scss" scoped>
