GPX

TIP

加载 GPX 数据

代码如下:

点我查看代码

<template>
  <div id="map"></div>
</template>

<script lang="ts" setup>
import { onMounted, onBeforeUnmount } from "vue";
import L from "leaflet";
import "leaflet-gpx";
import { MAPURL, ATTRIBUTIONS } from "../../../constants";

let map: L.Map | null = null;
const initMap = () => {
  //地图容器
  map = L.map("map", {
    //参考坐标系
    crs: L.CRS.EPSG3857,
    //显示中心
    center: [42.45, -71.11],
    //最小显示等级
    minZoom: 1,
    //最大显示等级
    maxZoom: 18,
    //当前显示等级
    zoom: 15,
  });
  //加载图层
  L.tileLayer(MAPURL, {
    noWrap: true,
    attribution: ATTRIBUTIONS,
  }).addTo(map);
  // 加载 gpx
  const gpx = "/gpx/fells_loop.gpx";
  // @ts-ignore
  new L.GPX(gpx, {
    async: true,
    marker_options: {
      startIconUrl: "/image/pin-icon-start.png",
      endIconUrl: "/image/pin-icon-end.png",
      shadowUrl: "/image/pin-shadow.png",
      wptIconUrls: {
        "": "/image/pin-icon-wpt.png",
      },
    },
  })
    .on("loaded", (e) => {
      map?.fitBounds(e.target.getBounds());
    })
    .addTo(map);
};
onMounted(() => {
  initMap();
});

// 销毁地图
onBeforeUnmount(() => {
  if (map) {
    map.remove();
    map = null;
  }
});
</script>

<!-- Add "scoped" attribute to limit CSS to this component only -->
<style scoped>
#map {
  height: 650px;
}
</style>
