前几天通过百度地图的鼠标绘制工具，实现对多边形的绘制并获取各个点的坐标http://www.cnblogs.com/fozero/p/5912287.html
现在我们使用百度地图的本地检索接口，来实现对地址的检索 ，并解析结果列表显示出来，包括坐标、地址等各个数据

在右上角输入要检索的地址，点击检索，将结果数据解析显示到结果列表中
上面的String.fromCharCode(65+i)是循环26个大小英文字母，输出A-Z
循环输出26个小写英文字母String.fromCharCode(97+i)，输出a-z
左边显示标注ABC等 ，由于地址检索接口结果列表显示顺序跟左边显示标注是一致的，所以，右边如果也要同样显示ABC标注，我们直接循环输出A-Z显示即可
看下最后实现的样子
