一、查看某个地区全部业务员的坐标
二、点击业务员坐标可展现具体信息、当前具体地址
三、点击某个业务员名字,自动关联到地图上的位置
四、查看业务员当天的行程轨迹
五、动态切换地图上坐标的自定义图标
六、支持展现全部业务员在可视区内(自适应缩放地图比例,展现全部业务员位置)javascript
之因此没有选择用vue-baidu-map,是由于有bug。。。php
若是你以前没有接触过地图方面的开发,建议先去官网熟悉一下api。
百度地图API(javascript API)
具体的参考类
大概会用到如下几个api:css
先看一下最终的效果图html
显示轨迹的模块vue
项目是vue项目 我贴一下map.vue的文件代码
html代码👇
只须要一个显示地图的divjava
<template> <div class="main"> <div id="container" class="bm-view"> </div> <div class="btn__group"> <button @click="changeType('all')" :class="{'active': item === 'all'}">所有</button> <button @click="changeType('path')" :class="{'active': item === 'path'}" v-show="currentItem==='car'">轨迹</button> </div> </div> </template>

css样式代码我就不贴出来了,大家随意发挥~api
注意的问题点以下👇
GCJ02:又称火星坐标系,是由中国国家测绘局制订的地理信息系统的坐标系统。由WGS84坐标系经加密后的坐标系。
BD09:为百度坐标系,在GCJ02坐标系基础上再次加密。其中bd09ll表示百度经纬度坐标,bd09mc表示百度墨卡托米制坐标。
非中国地区地图,服务坐标统一使用WGS84坐标。
百度对外接口的坐标系为BD09坐标系,并非GPS采集的真实经纬度,在使用百度地图JavaScript API服务前,需先将非百度坐标经过坐标转换接口转换成百度坐标。
代码有点乱, 我本身都有点难理清楚,若是有小伙伴遇到问题了能够联系我QQ:602353272若是我分享的这个文章对你有帮助的话,不要吝啬你的赞,给我点个赞吧。谢谢~~
