【Vue】amap 定位实现

vue-amap 定位实现

官方文档：vue-amap

需求：当进入地图页面，定位到当前位置，显示点坐标，搜索框显示当前坐标的具体位置。点击地图，搜索框显示点击坐标的具体位置，搜索后地图中心点为搜索后的位置。

• 注册并登录高德控制台

• 创建应用申请 key，切记一定要选择 web 端(JS API)

• 项目中安装地图依赖：npm install vue-amap -S

• main.js 中引入

import aMap from 'vue-amap'

Vue.use(aMap)

aMap.initAMapApiLoader({
  key: '3025364******22bdaf9b6', // 你的key
  plugin: ['AMap.Autocomplete', 'AMap.PlaceSearch', 'AMap.Scale', 'AMap.OverView', 'AMap.ToolBar', 'AMap.MapType', 'AMap.Geolocation', 'AMap.Geocoder', 'AMap.AMapManager', 'AMap.Marker'], // 应用功能项
  v: '1.4.4', // 版本
  uiVersion: '1.0', // ui版本
})

• 创建地图组件

<template>
  <div class="container">
    <div class="search-box">
      <input v-model="searchKey" type="search" id="search" />
      <button @click="searchByHand">搜索</button>
      <button @click="submitAddress" style="margin-left: 2px">确认</button>
      <div class="tip-box" id="searchTip"></div>
    </div>
    <el-amap class="amap-box" :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>
</template>

<style>
.container {
  width: 100%;

  position: relative;

  top: 50%;
  transform: translate3d(-50%, -50%, 0);

  position: absolute;
  z-index: 5;
  width: 70%;

  top: 10px;
  height: 30px;
}

.search-box input {
  float: left;
  width: 59%;
  height: 100%;
  border: 1px solid #30ccc1;
  padding: 0 8px;
  outline: none;
}
