帮朋友做的，顺便记录下来，以后使用，主要是在腾讯地图上点选、主要是在屏幕点选坐标，线选坐标，多边形坐标，代码写的优点乱，也没时间整理了，下面是图，觉得适合自己了，再向后看代码。

腾讯地图获取所选区域坐标_地图

腾讯地图获取所选区域坐标_地图_02

腾讯地图获取所选区域坐标_鼠标指针_03

首先是html页面


<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <link href="style.css" rel="stylesheet" type="text/css">
    <script charset="utf-8" src="http://map.qq.com/api/js?v=2.exp"></script>
    <title>获取腾讯地图坐标</title>

</head>
<body>
<div id="container">
</div>
<div id="menu">
    <img src="img/scatter_plot_.png"  id="point" οnclick="point()" title="点坐标">
    <img src="img/polyline.png" id="line"  οnclick="line()" title="线坐标">
    <img src="img/rectangle_stroked.png" id="rectangle"  οnclick="rectangle()" title="矩形坐标">
</div>
<div id="result">

</div>
<script src="getPoint.js"></script>
</body>
</html>




下面是js
