vue-amap安装和用法步骤
之前分享了异步加载高德地图api的用法，现在记录一下vue-amap的用法。
vue-amap是饿了么开源的一套基于 Vue 2.0 和高德地图的地图组件。 数据状态与地图状态单向绑定，开发者无需关心地图的具体操作。
官方文档：https://elemefe.github.io/vue-amap/
步骤如下：1.npm 安装
npm install vue-amap --save
如果是CDN方式，目前可通过unpkg.com/vue-amap获取最新版本的资源。
<script src="https://unpkg.com/vue-amap/dist/index.js"></script>
2.使用实例
实例需求描述：搜索并选择地址，选中后地图定位到该地址，并获取经纬度自动填入下方的输入框中。
注：实例中使用的框架是ElementUI，其表单组件使用比较方便。
实现步骤：（1）安装后在main.js中设置以下内容：
import VueAMap from "vue-amap";
Vue.use(VueAMap);
// 初始化vue-amap
VueAMap.initAMapApiLoader({
key: "your key", // 这里写你申请的高德地图的key
plugin: ["AMap.Autocomplete", "AMap.Geocoder", "AMap.Geolocation"],
v: "1.4.15",
uiVersion: "1.1"
});
（2）定义地图搜索组件 base/mapSearch/baseMapSearch.vue
<template>
<div>
<div class="search-box">
<el-input
v-model="searchKey"
type="search"
id="search"
placeholder="请输入详细地址"
></el-input>
<!--<button @click="searchByHand">搜索</button>-->
<div class="tip-box" id="searchTip"></div>
</div>
<!--
amap-manager： 地图管理对象
vid：地图容器节点的ID
zooms： 地图显示的缩放级别范围，在PC上，默认范围[3,18]，取值范围[3-18]；在移动设备上，默认范围[3-19]，取值范围[3-19]
center： 地图中心点坐标值
plugin：地图使用的插件
events： 事件
-->
<div class="amap-box">
<el-amap
:amap-manager="amapManager"
:vid="'amap-vue'"
:zoom="zoom"
:plugin="plugin"
:center="center"
:events="events"
>
<!-- 标记 -->
<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 {
props: ["city", "value", "longitude", "latitude", "isEdit"],
data() {
let self = this;
return {
address: null,
searchKey: "",
amapManager,
markers: [],
searchOption: {
city: this.city ? this.city : "全国",
citylimit: true
},
center: [121.329402, 31.228667],
zoom: 17,
lng: 0,
lat: 0,
loaded: false,
events: {
init() {
lazyAMapApiLoaderInstance.load().then(() => {
self.initSearch();
});
},
// 点击获取地址的数据
click(e) {
self.markers = [];
let { lng, lat } = e.lnglat;
self.lng = lng;
self.lat = lat;
self.center = [lng, lat];
self.markers.push([lng, lat]);
// 这里通过高德 SDK 完成。
let geocoder = new AMap.Geocoder({
radius: 1000,
extensions: "all"
});
geocoder.getAddress([lng, lat], function(status, result) {
if (status === "complete" && result.info === "OK") {
if (result && result.regeocode) {
self.address = result.regeocode.formattedAddress;
self.searchKey = result.regeocode.formattedAddress;
self.$emit("updateLocation", lng, lat, self.searchKey);
self.$nextTick();
}
}
});
}
},
// 一些工具插件
plugin: [
{
// 定位
pName: "Geolocation",
events: {
init(o) {
// o是高德地图定位插件实例
o.getCurrentPosition((status, result) => {
if (result && result.position) {
if (self.isEdit) {
// 设置经度
self.lng = self.longitude;
// 设置维度
self.lat = self.latitude;
// 设置坐标
self.center = [self.longitude, self.latitude];
self.markers.push([self.longitude, self.latitude]);
} else {
// 设置经度
self.lng = result.position.lng;
// 设置维度
self.lat = result.position.lat;
// 设置坐标
self.center = [self.lng, self.lat];
self.markers.push([self.lng, self.lat]);
}
// load
self.loaded = true;
// 页面渲染好后
self.$nextTick();
}
});
}
}
}
]
};
},
created() {
if (this.value) {
this.searchKey = this.value;
this.address = this.value;
}
if (this.longitude && this.latitude) {
this.lng = this.longitude;
this.lat = this.latitude;
this.center = [this.longitude, this.latitude];
this.markers.push([this.longitude, this.latitude]);
}
},
methods: {
// 选择地址后自动定位到当前地址附近
updateAddress(value, longitude, latitude) {
this.searchKey = value;
this.address = value;
this.lng = longitude;
this.lat = latitude;
this.center = [longitude, latitude];
this.markers.push([longitude, latitude]);
},
initSearch() {
let vm = this;
let map = this.amapManager.getMap();
AMapUI.loadUI(["misc/PoiPicker"], function(PoiPicker) {
let poiPicker = new PoiPicker({
input: "search",
placeSearchOptions: {
map: map,
pageSize: 10
},
suggestContainer: "searchTip",
searchResultsContainer: "searchTip"
});
vm.poiPicker = poiPicker;
// 监听poi选中信息
poiPicker.on("poiPicked", function(poiResult) {
let source = poiResult.source;
let poi = poiResult.item;
if (source !== "search") {
poiPicker.searchByKeyword(poi.name);
} else {
poiPicker.clearSearchResults();
vm.markers = [];
let lng = poi.location.lng;
let lat = poi.location.lat;
let address = poi.name; // poi.cityname + poi.adname + poi.name
vm.center = [lng, lat];
vm.markers.push([lng, lat]);
vm.lng = lng;
vm.lat = lat;
vm.address = address;
vm.searchKey = address;
vm.$emit("updateLocation", lng, lat, vm.searchKey);
}
});
});
},
searchByHand() {
if (this.searchKey !== "" && this.poiPicker) {
this.poiPicker.searchByKeyword(this.searchKey);
}
}
}
};
</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>
这里样式使用了stylus，可自行转换其他样式。
（3）在组件中使用地图搜索组件，这里以弹窗为例
<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="选择地址" 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="经度">
<el-input
v-model.number="form.addLon"
:maxlength="15"
placeholder="请输入经度"
></el-input>
</el-form-item>
</el-col>
<el-col :span="12" class="right-label-form-item">
<el-form-item prop="addLat" label="纬度">
<el-input
v-model.number="form.addLat"
:maxlength="15"
placeholder="请输入纬度"
></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: "请输入地址",
trigger: ["blur", "change"]
}
],
addLat: [
{
required: true,
message: "请输入纬度",
trigger: ["blur", "change"]
}
],
addLon: [
{
required: true,
message: "请输入经度",
trigger: ["blur", "change"]
}
],
}
};
},
created() {
if (this.isEdit) {
this.initForm();
}
},
methods: {
// 初始化表单
initForm() {
this.title = "修改地址";
if (this.detail) {
this.form = { ...this.detail };
}
},
// 地图搜索选址
updateLocation(lng, lat, address) {
this.form.addLon = lng;
this.form.addLat = lat;
this.form.address = address;
},
handleClose() {
this.$emit("update:visible", false);
}
}
};
</script>
（4）这时，如果项目中使用了ESlint，会报AMap、AMapUI未定义的错误，我们需要在.eslintrc.js文件中定义globals属性：
module.exports = {
// ...
globals: {
AMap: false,
AMapUI: false
}
};
这样就写好了，效果如图：
