百度地图API 添加标签

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)：
