1.手動建立數據，實際項目則是接受GPS信息javascript

/創建座標點：
// lng：經度 lat：緯度
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.建立添加標註點到地圖，併爲標註點添加點擊事件css

//建立標註點並添加到地圖中
function addMarker(points) {
    //循環創建標註點
    for(var i=0, pointsLen = points.length; i<pointsLen; i++) {
        var point = new BMap.Point(points[i].lng, points[i].lat); //將標註點轉化成地圖上的點
        var marker = new BMap.Marker(point); //將點轉化成標註點
        map.addOverlay(marker);  //將標註點添加到地圖上
        //添加監聽事件
        (function() {
            var thePoint = points[i];
            marker.addEventListener("click",
            //顯示信息的方法
                function() {
                showInfo(this,thePoint);
            });
         })();  
    }
}

3.編寫信息顯示方法html

function showInfo(thisMarker,point) {
    //獲取點的信息
    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;">名稱：</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+'">詳情</a></li>'  
    +'</ul>';
    var infoWindow = new BMap.InfoWindow(sContent); //建立信息窗口對象
    thisMarker.openInfoWindow(infoWindow); //圖片加載完後重繪infoWindow
}

4.建立地圖java

//建立地圖
var map = new BMap.Map("allmap");    
map.centerAndZoom(new BMap.Point(116.404, 39.915), 11);  // 設置中心點
map.centerAndZoom( "衡陽");       //指定中心城市
map.setCurrentCity("衡陽");          
map.addControl(new BMap.MapTypeControl());  //設置可拖拽 
map.enableScrollWheelZoom(true);  //添加滾輪縮放   
addMarker(points); //添加標註
</script>

Tip: 想使用百度地圖api須要申請一個ak，申請方法就不介紹了，百度一大堆.api

1.5 版本完整代碼(不包括api的ak 須要本身申請)：閉包
