Vue集成百度地图实现位置选择

百度地图选择地址效果

具体效果如下图所示

百度地图选择地址

集成百度地图的具体实现

技术方案: Vue + ElementUI + 百度地图 JavaScript API v3.0

工程目录结构图:

```

参考文档:https://lbsyun.baidu.com/index.php?title=jspopular3.0/guide/getkey

第一步:引入百度地图 JavaScript API v3.0 文件

修改文件:public -> index.html

<script type="text/javascript" src="http://api.map.baidu.com/api?v=3.0&ak=你的秘钥"></script>

第二步:编写百度地图选择位置组件

新增文件:src -> components -> BMapAddressSelect -> index.vue

<template>
  <el-dialog title="位置选择" :visible.sync="openMap" width="900px" append-to-body>
    <el-form label-width="80px">

          </el-form-item>
        </el-col>
        <el-col :span="14">
          <el-form-item label="当前地址">

</script>

<style lang="scss">
// 防止地图自动完成的对象被遮挡

第三步:使用百度地图选择位置组件

<template>
  <div class="app-container">
    <el-row>
      <el-col :span="12">
        <el-form ref="addressInfo" :model="addressInfo" :rules="rules" label-width="100px">
          <el-form-item label="门店地址" prop="address">
            <el-input placeholder="请选择门店地址" v-model="addressInfo.address" disabled>
              <template slot="prepend">{{addressInfo.province}}{{addressInfo.city}}{{addressInfo.district}}</template>
              <el-button slot="append" icon="el-icon-map" @click="showMap" type="primary">选择地址</el-button>
            </el-input>
          </el-form-item>
          <el-row>
            <el-col :span="12">
              <el-form-item label="门店经度" prop="longitude">
                <el-input v-model="addressInfo.longitude" placeholder="请输入经度" disabled />
              </el-form-item>
            </el-col>
            <el-col :span="12">
              <el-form-item label="门店纬度" prop="latitude">
                <el-input v-model="addressInfo.latitude" placeholder="请输入纬度" disabled />
              </el-form-item>
            </el-col>
          </el-row>
        </el-form>
      </el-col>
    </el-row>
	
	<!-- 百度地图位置选择 -->
    <BMapAddressSelect ref="bmapAddressSelect" @confirmMapAddress="confirmMapAddress"></BMapAddressSelect>

  </div>
</template>

<script>

import BMapAddressSelect from "@/components/BMapAddressSelect/index";

export default {
  data() {
    return {
      // 位置信息
      addressInfo: {},
      // 表单校验
      rules: {},
    };
  },
  components: {
    BMapAddressSelect,
  },
  methods: {
    /** 显示地图 */
    showMap() {
      this.$refs.bmapAddressSelect.show();
    },

    /** 确认地图地址 */
    confirmMapAddress(addressInfo) {
      this.addressInfo = addressInfo;
    },
  },
};
</script>
