vue-amap安裝和用法步驟

之前分享瞭異步加載高德地圖api的用法,現在記錄一下vue-amap的用法。

vue-amap是餓瞭麼開源的一套基於 Vue 2.0 和高德地圖的地圖組件。 數據狀態與地圖狀態單向綁定,開發者無需關心地圖的具體操作。

官方文檔:https://elemefe.github.io/vue-amap/

步驟如下:

1.npm 安裝

npm install vue-amap –save

如果是CDN方式,目前可通過unpkg.com/vue-amap獲取最新版本的資源。

<script src=”https://unpkg.com/vue-amap/dist/index.js”></script>

2.使用實例

實例需求描述:搜索並選擇地址,選中後地圖定位到該地址,並獲取經緯度自動填入下方的輸入框中。

註:實例中使用的框架是ElementUI,其表單組件使用比較方便。

實現步驟:

(1)安裝後在main.js中設置以下內容:

import VueAMap from "vue-amap";
Vue.use(VueAMap);
// 初始化vue-amap
VueAMap.initAMapApiLoader({
  key: "your key", // 這裡寫你申請的高德地圖的key
  plugin: ["AMap.Autocomplete", "AMap.Geocoder", "AMap.Geolocation"],
  v: "1.4.15",
  uiVersion: "1.1"
});

(2)定義地圖搜索組件 base/mapSearch/baseMapSearch.vue

<template>
  <div>
    <div class="search-box">
      <el-input
        v-model="searchKey"
        type="search"
        id="search"
        placeholder="請輸入詳細地址"
      ></el-input>
      <!--<button @click="searchByHand">搜索</button>-->
      <div class="tip-box" id="searchTip"></div>
    </div>
    <!--
      amap-manager: 地圖管理對象
      vid:地圖容器節點的ID
      zooms: 地圖顯示的縮放級別范圍,在PC上,默認范圍[3,18],取值范圍[3-18];在移動設備上,默認范圍[3-19],取值范圍[3-19]
      center: 地圖中心點坐標值
      plugin:地圖使用的插件
      events: 事件
    -->
    <div class="amap-box">
      <el-amap
        :amap-manager="amapManager"
        :vid="'amap-vue'"
        :zoom="zoom"
        :plugin="plugin"
        :center="center"
        :events="events"
      >
        <!-- 標記 -->
        <el-amap-marker
          v-for="(marker, index) in markers"
          :position="marker"
          :key="index"
        ></el-amap-marker>
      </el-amap>
    </div>
  </div>
</template>
<script>
import { AMapManager, lazyAMapApiLoaderInstance } from "vue-amap";
let amapManager = new AMapManager();
export default {

  data() {
    let self = this;
    return {

      events: {

          lazyAMapApiLoaderInstance.load().then(() => {
            self.initSearch();
          });
        },
        // 點擊獲取地址的數據
        click(e) {

          }
        }
      ]
    };
  },
  created() {
    if (this.value) {
      this.searchKey = this.value;
      this.address = this.value;
    }
    if (this.longitude && this.latitude) {
      this.lng = this.longitude;
      this.lat = this.latitude;
      this.center = [this.longitude, this.latitude];
      this.markers.push([this.longitude, this.latitude]);

  },
  methods: {
    // 選擇地址後自動定位到當前地址附近
    updateAddress(value, longitude, latitude) {
      this.searchKey = value;
      this.address = value;
      this.lng = longitude;
      this.lat = latitude;
      this.center = [longitude, latitude];
      this.markers.push([longitude, latitude]);
    },
    initSearch() {
      let vm = this;
      let map = this.amapManager.getMap();
      AMapUI.loadUI(["misc/PoiPicker"], function(PoiPicker) {
        let poiPicker = new PoiPicker({
          input: "search",
          placeSearchOptions: {
            map: map,
            pageSize: 10
          },
          suggestContainer: "searchTip",
          searchResultsContainer: "searchTip"
        });
        vm.poiPicker = poiPicker;
        // 監聽poi選中信息
        poiPicker.on("poiPicked", function(poiResult) {
          let source = poiResult.source;
          let poi = poiResult.item;
          if (source !== "search") {
            poiPicker.searchByKeyword(poi.name);
          } else {
            poiPicker.clearSearchResults();
            vm.markers = [];
            let lng = poi.location.lng;

      }
    }
  }
};
</script>
<style lang="stylus">
.search-box {
  margin-top: 6px;
  width: 100%;
}
.search-box input {
  padding: 0 15px;
  width: 100%;
  height: 32px;
  line-height: 32px;
  color: #606266;
  border: 1px solid #dcdfe6;
  border-radius: 4px;
}
.search-box input:focus {
  border-color: #409eff;
  outline: 0;
}
.search-box input::-webkit-input-placeholder {
  color: #c0c4cc;
}
.tip-box {
  width: 100%;
  max-height:280px;
  position: absolute;
  top: 72px;
  z-index: 10000;
  overflow-y: auto;
  background-color: #fff;
}
</style>
<style>
.amap-ui-poi-picker-sugg,
.amap_lib_placeSearch {
  border: 1px solid #eee;
  border-radius: 4px;
}
.amap-box {
  height: 200px;
}
</style>

這裡樣式使用瞭stylus,可自行轉換其他樣式。

(3)在組件中使用地圖搜索組件,這裡以彈窗為例

<template>
  <el-dialog
    :title="title"
    :visible.sync="visible"
    :before-close="handleClose"
    width="600px"
    append-to-body
    :close-on-click-modal="false"
    :close-on-press-escape="false"
  >
    <div class="form-info">
      <el-form
        :model="form"
        ref="form"
        :rules="rules"
        size="small"
        label-width="110px"
      >
        <el-form-item label="選擇地址" prop="address">
          <base-map-search
            ref="mapSearch"
            :city="form.city"
            :value="form.address"
            :longitude="form.addLon"
            :latitude="form.addLat"
            :isEdit="isEdit"
            @updateLocation="updateLocation"
          />
        </el-form-item>
        <el-row>
          <el-col :span="12">
            <el-form-item prop="addLon" label="經度">
              <el-input
                v-model.number="form.addLon"
                :maxlength="15"
                placeholder="請輸入經度"
              ></el-input>
            </el-form-item>
          </el-col>
          <el-col :span="12" class="right-label-form-item">
            <el-form-item prop="addLat" label="緯度">
              <el-input
                v-model.number="form.addLat"
                :maxlength="15"
                placeholder="請輸入緯度"
              ></el-input>
            </el-form-item>
          </el-col>
        </el-row>
      </el-form>
    </div>
  </el-dialog>
</template>
<script>
import BaseMapSearch from "../base/mapSearch/baseMapSearch";
export default {
    props: ["visible", "isEdit", "detail"],
    components: {
      BaseMapSearch
    },
    data() {
        return {
            title: "添加地址",
            form: {
                address: "",
                addLon: "",
                addLat: ""
            },
            rules: {
                address: [
                  {
                    required: true,
                    message: "請輸入地址",
                    trigger: ["blur", "change"]
                  }
                ],
                addLat: [
                  {
                    required: true,
                    message: "請輸入緯度",
                    trigger: ["blur", "change"]
                  }
                ],
                addLon: [
                  {
                    required: true,
                    message: "請輸入經度",
                    trigger: ["blur", "change"]
                  }
                ],
            }
        };
    },
    created() {
      if (this.isEdit) {
        this.initForm();
      }
    },
    methods: {
        // 初始化表單
        initForm() {
          this.title = "修改地址";
          if (this.detail) {
            this.form = { ...this.detail };
          }
        },
        // 地圖搜索選址
        updateLocation(lng, lat, address) {
          this.form.addLon = lng;
          this.form.addLat = lat;
          this.form.address = address;
        },
        handleClose() {
          this.$emit("update:visible", false);
        }
    }
};
</script>

(4)這時,如果項目中使用瞭ESlint,會報AMap、AMapUI未定義的錯誤,我們需要在.eslintrc.js文件中定義globals屬性:

module.exports = {
    // ...
    globals: {
      AMap: false,
      AMapUI: false
    }
};

這樣就寫好瞭,效果如圖:
