首先需要在index.html中引入高德地图的js链接，key需要换成你自己的key

最近有个需求是实现一个使用地图搜索定位的功能，在网上参考了下其他的文章，感觉不是很完善，自己整理了一下，可以实现点击定位，搜索列表定位等功能，可能有些地方是多余的，需要的自己看着改下

<script type="text/javascript" src="https://webapi.amap.com/maps?v=1.4.14&key=你的key"></script>

效果图如下

下边就是实现过程

html部分


<template>
  <div id="wrap">
    <div id="searchWrap">
      <div class="searchWrap">
        <input type="text" v-model="address" @input="search"><button @click="search">搜索</button>
      </div>
      <div id="result" class="amap_lib_placeSearch" v-show="hide">
        <div class="amap_lib_placeSearch_list amap-pl-pc" v-for="(item,index) in poiArr"
           @click="openMarkerTipById(index,$event)"
           @mouseout="onmouseout_MarkerStyle(index+1,$event)"
           :key="index">
          <div class="poibox" style="border-bottom: 1px solid #eaeaea">
            <div class="amap_lib_placeSearch_poi poibox-icon" :class="index==selectedIndex?'selected':''">{{index+1}}</div>
            <div class="poi-img" v-if="item.url" :style="'background-image:url('+item.url+'?operate=merge&amp;w=90&amp;h=56&amp;position=5)'"
            ></div>
            <h3 class="poi-title" >
              <span class="poi-name">{{item.name}}</span>
            </h3>
            <div class="poi-info">
              <p class="poi-addr">地址：{{item.address}}</p>
              <p class="poi-tel">电话：{{item.tel}}</p>
            </div>
            <div class="clear"></div>
          </div>
        </div>
      </div>
    </div>
    <div id="iCenter"></div>
    <button class="btn" @click="fetAddressName">获取当前位置和名字</button>
  </div>
