封装一个地图选择器（基于高德地图）

效果如图：



能搜索选择地址，也能点击地图选择地址。
代码如下：
首先下载loader。npm i @amap/amap-jsapi-loader --save

<template>
  <div>
    <el-dialog
      title="选择地址"
      :visible.sync="isMap"
      :close-on-press-escape="false"
      :close-on-click-modal="false"
      :show-close="false"
      width="700"
    >
      <div>
        <div class="sear-map">
          <el-row :gutter="20">
            <el-col :span="20">
              <!-- <el-input v-model="address" placeholder="输入详细地址"></el-input> -->
              <el-select
                style="width: 100%"
                v-model="address"

                reserve-keyword
                clearable
                placeholder="搜地点"
                :remote-method="remoteMethod"
                :loading="loading"

                  :value="item.id"
                >
