项目中的百度地图添加标注，动态弹框

1.最近项目开发中，用到了地图，需求是使用百度地图

初始化地图：

var list = "";
	var map = "";
	var drawingManager = "";
	if (typeof (BMap) == 'undefined') {
		//地图加载失败
		document.getElementById("allmap").innerHTML = "地图加载失败";
	} else {
		/** 百度地图API功能 **/
		map = new BMap.Map("allmap");
		var point = "";
		var xpointer = document.getElementById("mxpoint").value;
		var ypointer = document.getElementById("mypoint").value;
		if (xpointer != null) {
			point = new BMap.Point(xpointer, ypointer);
		} else {
			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。
		map.enableScrollWheelZoom(); //启用滚轮放大缩小	
		map.addControl(new BMap.NavigationControl()); // 添加平移缩放控件
		map.addControl(new BMap.ScaleControl()); // 添加比例尺控件

		window.clickPointer = "tuodong";
		circle();
	}

2.项目需求是每隔30秒获取当前在线打开GPS的用户

function showTimer() {
        var data = {};
        var url_validate = $ctx + "/ddtinfo/ddtinfo!validateMapUser.action";
        App.post(url_validate, data, function(response) {
            map.clearOverlays();
            if (clickPointer == "huayuan") {
                circle();
            }

            var err = App.err(response);
            if (err) {
                alert(err.message);
            } else {
                list = new Array();
                $.each(response || [], function(i, o) {
                    list[i] = o;
                    var pt = new BMap.Point(o.xpoint, o.ypoint);
                    var imgstr = $ctx + "/images/blue.png";
                    var myIcon = new BMap.Icon(imgstr, new BMap.Size(38, 47));
                    var marker = new BMap.Marker(pt, {
                        icon : myIcon
                    });
                    if(leftMapUserId != undefined){
                        if(leftMapUserId == o.yonghuid){
                            marker.setTop(true,27000000);
                        }
                    }
                    map.addOverlay(marker);

                    var myLabel = new BMap.Label(o.yonghuname, {
                        offset : new BMap.Size(-10, -25)
                    });
                    myLabel.setStyle({
                        "color" : "white", //颜色     
                        "fontSize" : "12px", //字号     
                        "border" : "0", //边 
                        "background" : "#00CCFF", //背景颜色
                        "textAlign" : "center", //文字水平居中显示      
                        "lineHeight" : "20px", //行高，文字垂直居中显示
                        "width" : "50px",
                        "border-radius" : "5px" //圆角    

                    });
                    marker.setLabel(myLabel);

                    marker.addEventListener("click",
                            function() {
                                var yonghuid = o.yonghuid;
                                var yonghuname = o.yonghuname.replace(/[ ]/g,
                                        "");
                                var mrzuname = o.morenzuname;
                                var morenzuid = o.morenzuid;
                                showDiv(yonghuid, yonghuname, morenzuid,
                                        mrzuname, this);

                            });
                })
            }
        });
        setTimeout("showTimer()", 30000);
    }

3.点击标注动态显示信息窗口，在网上看到很多人，提问为什么百度地图点击标注显示的都是最后那个人的信息，使用下面方法ok

function showDiv(yonghuid, yonghuname, morenzuid, mrzuname, marker) {
var content = '
'
                    + ''
                    + mrzuname
                    + '
'
                    + '         morenzuid
                    + ','
                    + yonghuid
                    + ',this)" alt=""/>   '
                    + ' yonghuname
                    + '\''
                    + ','
                    + yonghuid
                    + ')" alt=""/>   '
                    + ' yonghuname
                    + '\''
                    + ','
                    + yonghuid
                    + ')" alt=""/>   '
                    + ' yonghuname
                    + '\''
                    + ','
                    + yonghuid
                    + ')" alt=""/>'
                    + '
';
            var infoWindow1 = new BMap.InfoWindow(content, {
                enableMessage : false,
                width : 130,
                height : 88,
                title : yonghuname.toString() + "(" + yonghuid.toString() + ")"
            });

            marker.openInfoWindow(infoWindow1);
        }
