谷歌地图API问题

小p变砖头 2010-07-28 10:08:33

大家好！我最近研究Google Maps API。想创建一个这样的应用：1>地图开始自动定位一经纬度并显示标签 2>当用户单击标签时显示掉话两个字。（移动前后都可实现）3>当用户移动地图时在地图下方显示移动后地图的经纬度。遇到问题：点击标签时并不显示信息，而是移动map并触发moveMap函数。请问该问题应如何解决，谢谢！（还有一个问题，如何获得当前鼠标指向的或点击的位置的经纬度，而不是地图中心的？）
附上源代码：
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
