最近写项目的时候，做到了考勤打卡的模块内容，需要选择考勤打卡的位置信息以及打卡的范围展，所以做出以下的记录，方便大家参考学习（如下图展示）

一、创建百度地图账号，获取秘钥

首先得有百度地图的账号，点此链接（百度地图）

二、 引入插件

1、安装vue-baidu-map

npm install vue-baidu-map --save

2、在main.js中引入

import Vue from 'vue'
import BaiduMap from 'vue-baidu-map'Vue.use(BaiduMap, {ak: '此处为百度地图申请的密钥'
})

三、 简单使用

以下就不多介绍了，直接上完整代码

// 引入
npm install vue-baidu-map --save

引入map.vue页面

// point传值  gainLocation 获取点位的信息
<map :point="point"  @gainLocation="gainLocation" ></map>data() {return {point:{"lng": 120.306731,  //坐标"lat": 31.581733, value:'三阳广场',    // 位置信息scope:50			// 范围}}},gainLocation(row){console.log(row)}

创建map.vue页面

<template><div><el-button @click="open">打开地图</el-button<el-dialog title="地图" :visible.sync="dialogs" v-if="dialogs" ><div><el-autocomplete style="width: 100%" :popper-append-to-body="false"v-model="value" :fetch-suggestions="querySearchAsync" :trigger-on-focus="false" placeholder="输入地址查找点位信息"@select="handleSelect" ><i slot="prefix" class="el-input__icon el-icon-search"></i><template slot-scope="{ item }"><div class="flexs"><i class="el-icon-location" style="font-size:25px;color:#409eff"></i><div style="margin-left:15px" class="flcol"><span style="color:#409eff;">{{ item.title }}</span><span style="color:#999">{{ item.address }}</span></div></div></template></el-autocomplete></div><div ><baidu-map class="map"  :center="circleCenter" :zoom="zoom" :scroll-wheel-zoom="true" @ready="handler" /></div><span slot="footer" class="dialog-footer"><el-button @click="subMit" type="primary">确 定</el-button><el-button @click="dialogs = false">取消</el-button></span></el-dialog></div>
</template><script>
