1.实现功能：通过给定的坐标点，往地图中添加标注点，点击标注点，显示改点的详细信息。
2.效果图：
演示链接：:8080/BMap/MapTest1.html
3.核心方法：
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":"","id":1,"name":"p1"}, {"lng":112.59,"lat":26.90,"url":"","id":2,"name":"p2"}, {"lng":112.57,"lat":26.88,"url":"","id":3,"name":"p3"} ];
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);});})(); }}
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}
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.
完整代码(不包括api的ak 需要自己申请)：
