接这篇文章
本文引入Leaflet.Editable，在此基础上对点线面进行编辑
借鉴文章
官方demo

首先安装依赖

cnpm install leaflet-editable --save

引入js文件，附代码：

<template>
  <div class="map">
    <div id="mapView"></div>
    <div id="tooltip"></div>
    <div class="tools-box">
      <span
        class="tools-item iconfont icon-dingwei"
        :class="[idx == 1 ? 'tools-item-active' : '']"
        @click="change(1)"
        >标点</span
      >

      <el-divider direction="vertical"></el-divider>
      <span
        class="tools-item iconfont icon-segment"
        :class="[idx == 2 ? 'tools-item-active' : '']"
        @click="change(2)"
        >画线</span
      >

      <el-divider direction="vertical"></el-divider>
      <span
        class="tools-item iconfont icon-mian"
        :class="[idx == 3 ? 'tools-item-active' : '']"
        @click="change(3)"
        >画面</span
      >
    </div>

    <div class="sub-tools-box" v-show="showTools">
      <span
        v-show="idx == 2 || idx == 3"
        class="sub-tools-item iconfont icon-chexiao"
        @click="back"
        >撤销</span
      >
      <span

        class="sub-tools-item iconfont icon-huifu"
        @click="next"

      <span class="sub-tools-item iconfont icon-V1">取消</span>
      <span class="sub-tools-item iconfont icon-V">保存</span>
