    快速开始直通车

实现步骤(在vue中)

1.注册账号，获取Access Token

    详情点击

2.安装mapbox-gl

npm install --save mapbox-gl

3.引入css

<style scoped lang="scss">
  @import url('https://api.tiles.mapbox.com/mapbox-gl-js/v1.1.1/mapbox-gl.css');
</style>

4.初始化地图（3,4代码合并如下）

<template>
  <div class="macro-view">
    <div class="map-chart" ref="mapChart"></div>
  </div>
</template>

<script>
  import { ref, onMounted} from 'vue'
  import mapboxgl from 'mapbox-gl';
  export default {
    name: 'MapboxView',
    setup() {
      const mapChart = ref(null)
      mapboxgl.accessToken = 'Your Access Token';
      
      onMounted(() => {
        map = new mapboxgl.Map({
          container: mapChart.value,
          style: 'mapbox://styles/mapbox/dark-v9',
          zoom: 4,
          center: [110, 36]
        })
      })
      
      return {
        mapChart
      }
    }
  }
</script>

<style scoped lang="scss">
@import url('https://api.tiles.mapbox.com/mapbox-gl-js/v1.1.1/mapbox-gl.css');
.macro-view {
  height: 100%;
  .map-chart {
    height: 100%;
    ::v-deep .mapboxgl-control-container {
      display: none;
    }
  }
}
</style>
