TIP

导出PDF示例。

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.browser.print/dist/leaflet.browser.print";
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: [22.548857, 114.064839],
    // 缩放级别
    zoom: 10,
  });
  //加载图层
  L.tileLayer(MAPURL, {
    noWrap: true,
    attribution: ATTRIBUTIONS,
    crossOrigin: "anonymous",
  }).addTo(map);
  // 加载导出pdf控件
  L.control
    // @ts-ignore
    .browserPrint({
      title: "导出PDF地图",
      documentTitle: "printPdf",

      printModes: [
        // @ts-ignore
        L.BrowserPrint.Mode.Landscape("Tabloid", { title: "导出" }),
        // @ts-ignore
        L.BrowserPrint.Mode.Custom("B5", { title: "选择区域" }),
      ],
    })
    .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;
  color: #3a3a3a;
}
</style>
