最近由于项目中需要制作一个地图，用来选择活动地点，我就花了两天利用高德地图的javascriptAPI自制了一个地图的demo。在这了记录一下我学习的过程。
一、进入高德地图官网，再找到高德地图的开放平台，我是做前端的，所以使用的是javascriptAPI。
地图的功能很多，使用API可以自己定制自己想要的功能。在使用前需要自己申请一个Key，引入API的时候会用到这个key。
二、详细看一下左边的那一列各个里面的内容，看完了基本就知道怎么回事了，它提供的javascriptAPI其实就是一个接口，调用它的相应的接口就可以得到自己需要的数据。至于怎么调用接口，里面都讲的很清楚。
三、我觉得最有用，上手最快的位置还是那个实例中心，里面有很多不同的例子。基本能满足各种简单需求，我把其中的三个综合了一下，就实现了我想要的基本功能。下面是完整的代码页面，复制下来保存为html就可以看到我的那个效果了。（代码后面有张截图，可以看下效果）
