在这里插入图片描述

一、在vue项目中安装和基本使用

1. 安装

npm install vue-amap --save

2. 在vue项目中使用

1. 在main.js中引入

import VueAMap from 'vue-amap';

Vue.use(VueAMap);
VueAMap.initAMapApiLoader({
  key: "你的key",
  plugin: [
    "AMap.Scale",
    "AMap.OverView",
    "AMap.ToolBar",
    "AMap.MapType",
    "AMap.DistrictSearch",
  ],
  v: "1.4.4",
});
window._AMapSecurityConfig = {
  securityJsCode: "你的安全密钥",
};

2. demo显示高德地图

<template>
  <div>
    <div class="amap-page-container">
      <el-amap
        ref="map"
        vid="amapDemo"
        :center="center"
        :zoom="zoom"
        :plugin="plugin"
        :events="events"
        class="amap-demo"
      >
      </el-amap>
    </div>
  </div>
</template>

<script>
export default {
  data() {
    return {
      zoom: 12,
      center: [121.59996, 31.197646],
      events: {
        init: (o) => {
          console.log(o.getCenter());
          console.log(this.$refs.map.$$getInstance());
          o.getCity((result) => {
            console.log(result);
          });
        },
        moveend: () => {},
        zoomchange: () => {},
        click: (e) => {
          alert("map clicked");
        },
      },
      plugin: [
        "ToolBar",
        {
          pName: "MapType",
          defaultType: 0,
          events: {
            init(o) {
              console.log(o);
            },
          },
        },
      ],
    };
  },
};
</script>

<style lang="less" scoped>
.amap-page-container {
  width: 100%;
  height: 900px;
  position: relative;

  .amap-demo {
    width: 100%;
    height: 100%;
  }
}
</style>

                polygons = [];
                let bounds = result.districtList[0].boundaries;
                if (bounds) {
                    for (let i = 0, l = bounds.length; i < l; i++) {

                map.add(polygons)
                map.setFitView(polygons);

                let outer = [

                polygon.setPath(pathArray)
                map.add(polygon)
            })
        },
  }
};
</script>

<style lang="less" scoped>
