PC WEB端新增客户的时候需要填写客户地址和联系人信息，包括：省市区、街道、详细地址和经纬度以及联系人、固话和移动电话。获取客户地址信息之前用的是百度地图，由于小程序中客户拜访时，需要对客户进行定位、距离计算，所以客户经纬度都转换成了gcj02坐标。由于之前的百度地图经纬度坐标是百度自己坐标，因此需要获取经纬度时进行坐标转换，根据坐标点在百度地图上显示时需要二次转换，所以打算将百度地图替换成腾讯地图。
1、腾讯地图WEB API缺陷
先看下百度地图提供的2个现成功能，简单设置即可用：
1）城市切换
2）关键字输入提示
看完百度地图web api，再看看腾讯地图web api有没有这2功能：
1）城市切换，没有自带的，需要自行实现；
2）搜索关键字提示，提供了api接口，没有UI，需要自行完善；
2、基于jquery、bootstrap的腾讯地图城市切换和搜索关键字提示实现
1）页面截图
2）html代码

代码说明：
中文整理的代码，结构有点乱，勉强可以工作，仅供参考。
3、进一步优化
建议大家封装成一个弹出框组件，可以：
1）根据poi数据，初始化地图；
2）可以显示、隐藏弹出框组件；
3）可以有返回结果回调；
