教学开始~
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("http://dev.baidu.com/wiki/static/map/API/examples/images/Mario.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;"><strong>地址:</strong>北京市朝阳区高碑店小学旁 <strong>电话:</strong>010-59921010 <strong>口碑:</strong><img src="http://cdn2.iconfinder.com/data/icons/diagona/icon/16/031.png" alt="" /><img src="http://cdn2.iconfinder.com/data/icons/diagona/icon/16/031.png" alt="" /><img src="http://cdn2.iconfinder.com/data/icons/diagona/icon/16/031.png" alt="" /><img src="http://cdn2.iconfinder.com/data/icons/diagona/icon/16/031.png" alt="" /><img src="http://cdn2.iconfinder.com/data/icons/diagona/icon/16/031.png" alt="" /><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:
