0、如何创建百度地图？

打开记事本，拷贝以下代码，并把文件保存为htm格式。比如map.htm。然后双击图标运行。点击这里运行。

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>百度地图的Hello, World</title>
<script type="text/javascript" src="http://api.map.baidu.com/api?v=1.2"></script>
</head>
<body>
<div style="width:520px;height:340px;border:1px solid gray" id="container"></div>
</body>
</html>
<script type="text/javascript">
var map = new BMap.Map("container");            // 创建Map实例
var point = new BMap.Point(116.404, 39.915);    // 创建点坐标
map.centerAndZoom(point,15);                     // 初始化地图,设置中心点坐标和地图级别。
</script>

1、如何找到百度坐标？

利用百度提供的坐标拾取工具（网址：http://dev.baidu.com/wiki/static/map/API/tool/getPoint/）获取10个坐标点。

如下图，我输入“酒店”，在右侧会出现一些酒店的经纬度。也可直接在地图上点击，获取经纬度！

这样，我获取了10个经纬度，并把它们保存到一个数组里。我把获取的坐标全部罗列出来。

var point = [   //10个坐标点
new BMap.Point(116.411776,39.942833),
new BMap.Point(116.320791,40.003682),
new BMap.Point(116.275186,39.896095),
new BMap.Point(116.425098,39.946249),
new BMap.Point(116.359823,39.984761),
new BMap.Point(116.316479,39.98323),
new BMap.Point(116.385986,39.946124),
new BMap.Point(116.427545,40.00796),
new BMap.Point(116.446965,39.911603),
new BMap.Point(116.454579,39.946652)];

利用这些点创建标注，并且打到地图上。为了让大家看得清楚，这里就不使用循环了。如下：

var marker1 = new BMap.Marker(point[1]);  // 创建10个标注
var marker2 = new BMap.Marker(point[2]);
var marker3 = new BMap.Marker(point[3]);
var marker4 = new BMap.Marker(point[4]);
var marker5 = new BMap.Marker(point[5]);
var marker6 = new BMap.Marker(point[6]);
var marker7 = new BMap.Marker(point[7]);
var marker8 = new BMap.Marker(point[8]);
var marker9 = new BMap.Marker(point[9]);
var marker10 = new BMap.Marker(point[0]);

map.addOverlay(marker1);              // 将标注添加到地图中
map.addOverlay(marker2);
map.addOverlay(marker3);
map.addOverlay(marker4);
map.addOverlay(marker5);
map.addOverlay(marker6);
map.addOverlay(marker7);
map.addOverlay(marker8);
map.addOverlay(marker9);
map.addOverlay(marker10);

这里，一定要记得，如何给地图添加了标注，又没有调整到合适的地图视野，那些标注是看不见的。需要调整视野。

map.setViewport(point);         //调整地图的最佳视野为显示标注数组point

2、自定义覆盖物

如果你不满意标注图标，可以自己选择1）改变icon，或者2）自定义覆盖物。

1）改变icon

var myIcon = new BMap.Icon("/Article/UploadFiles/201108/20110807160821772.png", new BMap.Size(32, 70), {    //小车图片
    //offset: new BMap.Size(0, -5),    //相当于CSS精灵
    imageOffset: new BMap.Size(0, 0)    //图片的偏移量。为了是图片底部中心对准坐标点。
  });

var carMk = new BMap.Marker(point[0],{icon:myIcon});  //创建标注
map.addOverlay(carMk);    //添加marker到地图上

2）自定义覆盖物的示例：http://dev.baidu.com/wiki/static/map/API/examples/?v=1.2&3_12#3&12

到现在为止，你的地图会显示成这个样子。记得第一个标注麼？它已经被你设置成超级马里奥了！！

3、信息窗口内容

信息窗口里支持任意的htm代码。你可以这样来创建一个信息窗口。记住，要先定义opts，再定义信息窗口。简单的代码如下：

var opts = {
  width : 250,     // 信息窗口宽度
  height: 100,     // 信息窗口高度
  title : "Hello"  // 信息窗口标题
}
var infoWindow = new BMap.InfoWindow("World", opts);  // 创建信息窗口对象

复杂信息窗口的内容这样写，如下：

var opts1 = {title : '<span style="font-size:14px;color:#0A8021">如家快捷酒店</span>'};

var infoWindow1 = new BMap.InfoWindow("<div style='line-height:1.8em;font-size:12px;'><b>地址:</b>北京市朝阳区高碑店小学旁</br><b>电话:</b>010-59921010</br><b>口碑：</b><img src='/Article/UploadFiles/201108/20110807160822547.png' /><img src='/Article/UploadFiles/201108/20110807160822547.png' /><img src='/Article/UploadFiles/201108/20110807160822547.png' /><img src='/Article/UploadFiles/201108/20110807160822547.png' /><img src='/Article/UploadFiles/201108/20110807160822547.png' /><a style='text-decoration:none;color:#2679BA;float:right' href='#'>详情>></a></div>", opts1);  // 创建信息窗口对象，引号里可以书写任意的html语句。

4、打开信息窗口

给标注添加鼠标事件，当鼠标滑过标注的时候，打开信息窗口。

marker.addEventListener("mouseover", function(){this.openInfoWindow(infoWindow);});

所以，到现在为止，你的地图应该呈现这样一幅景象。

本案例全部代码如下：

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>酷讯酒店地图</title>

    offset: new BMap.Size(0, -5),    //相当于CSS精灵
    imageOffset: new BMap.Size(0, 0)    //图片的偏移量。为了是图片底部中心对准坐标点。
  });

var point = [new BMap.Point(116.411776,39.942833),new BMap.Point(116.320791,40.003682),new BMap.Point(116.275186,39.896095),new BMap.Point(116.425098,39.946249),new BMap.Point(116.359823,39.984761),new BMap.Point(116.316479,39.98323),new BMap.Point(116.385986,39.946124),new BMap.Point(116.427545,40.00796),new BMap.Point(116.446965,39.911603),new BMap.Point(116.454579,39.946652)];   //10个坐标点
