利用WeX5集成百度地图

最近做一个地图类的app
经过几天的摸索，终于完成百度地图集成的界面
先看效果：
1、加载完成之后，页面加载制定位置的地图
利用WeX5集成百度地图
2、顶部能够输入地图的关键字，地图显示符合条件的下拉列表

3、用户选择了相应的选项后，地图会移动到对应的地图范围，同时标题栏显示对应位置信息

4、当用户点击地图其他位置时，标识点移动到对应位置，标题栏的位置信息相应改变
5、当用户点击确认按钮时，用alert将当前标识点的地理信息alert出来

只需要把对应的代码片段复制到WeX5工具（开源免费的一个app开发工具）中相应的.w,.js..css中，右键浏览器运行就可以实地看到效果了
