1.手动创建数据,实际项目则是接受GPS信息
/建立坐标点:
// lng:经度 lat:纬度
var points = [
{"lng":112.58,"lat":26.89,"url":"http://www.baidu.com","id":1,"name":"p1"},
{"lng":112.59,"lat":26.90,"url":"http://www.mi.com","id":2,"name":"p2"},
{"lng":112.57,"lat":26.88,"url":"http://www.csdn.com","id":3,"name":"p3"}
];
2.创建添加标注点到地图,并为标注点添加点击事件
//创建标注点并添加到地图中 function addMarker(points) { //循环建立标注点 for(var i=0, pointsLen = points.length; i<pointsLen; i++) { var point = new BMap.Point(points[i].lng, points[i].lat); //将标注点转化成地图上的点 var marker = new BMap.Marker(point); //将点转化成标注点 map.addOverlay(marker); //将标注点添加到地图上 //添加监听事件 (function() { var thePoint = points[i]; marker.addEventListener("click", //显示信息的方法 function() { showInfo(this,thePoint); }); })(); } }
3.编写信息显示方法
function showInfo(thisMarker,point) { //获取点的信息 var sContent = ‘<ul style="margin:0 0 5px 0;padding:0.2em 0">‘ +‘<li style="line-height: 26px;font-size: 15px;">‘ +‘<span style="width: 50px;display: inline-block;">id:</span>‘ + point.id + ‘</li>‘ +‘<li style="line-height: 26px;font-size: 15px;">‘ +‘<span style="width: 50px;display: inline-block;">名称:</span>‘ + point.name + ‘</li>‘ +‘<li style="line-height: 26px;font-size: 15px;"><span style="width: 50px;display: inline-block;">查看:</span><a href="‘+point.url+‘">详情</a></li>‘ +‘</ul>‘; var infoWindow = new BMap.InfoWindow(sContent); //创建信息窗口对象 thisMarker.openInfoWindow(infoWindow); //图片加载完后重绘infoWindow }
4.创建地图
//创建地图 var map = new BMap.Map("allmap"); map.centerAndZoom(new BMap.Point(116.404, 39.915), 11); // 设置中心点 map.centerAndZoom( "衡阳"); //指定中心城市 map.setCurrentCity("衡阳"); map.addControl(new BMap.MapTypeControl()); //设置可拖拽 map.enableScrollWheelZoom(true); //添加滚轮缩放 addMarker(points); //添加标注 </script>
Tip: 想使用百度地图api需要申请一个ak,申请方法就不介绍了,百度一大堆.
1.5 版本 完整代码(不包括api的ak 需要自己申请):
