我有GPS跟踪服务器,并且数据库中添加了MarkerManager的清除标记问题。我的截断代码:

    {

    center = new GLatLng(52.536395, 13.42534);
    map.setCenter(center, 6);
    mgr =  new GMarkerManager(map,{maxZoom: 19});
    refreshMarkers();
    }
}
function refreshMarkers()
{
    clearTimeout(timeOut);
    GDownloadUrl('dane2.php', function(dane,respCode)
    {
        if(respCode==200)
        {
            var xml = GXml.parse(dane);
            var marker = dodajMarker(arguments, 15, 15);
        }
        else
        {
            alert('Cant open dane2.php');
        }
    });
    mgr.clearMarkers(); // ???
    timeOut=setInterval("refreshMarkers()",2000);
}
function dodajMarker(arguments, minZoom, maxZoom)
{
    var ikona = new GIcon();
    ikona.image = 'http://www.google.com/intl/en_ALL/mapfiles/dd-start.png';
    ikona.iconSize = new GSize(20, 34);
    ikona.iconAnchor = new GPoint(10, 34);
    var marker = new GMarker(new GLatLng(latitude,longitude),{icon: ikona});
    mgr.addMarker(marker,minZoom,maxZoom);
    return marker;
}

我的页面:http://m2mgsm.com/gps/index.php您可以登录:“admin”,密码:“12345”点击菜单中的测试地图(“Mapatesty” - 仅限波兰语,英文),然后选择IMEI(“Wybierz IMEI”) )例如355832010123229并检查Route(“Pokażtrasę:”)和From / To(“Od / Do”)日期(例如05.01.2012 / 05.01.2012)和“Filtruj”。您现在可以在框架中查看我的地图脚本的来源。我想刷新标记,例如, 3秒间隔和它的工作原理,但旧标记上的新标记是OVERLAY ... PS。抱歉我的英文。

你的错误是你的JS:

ReferenceError: kontener is not defined [http://m2mgsm.com/gps/mapatesty.php:259]
TypeError: Object #<yv> has no method 'clearMarkers' [http://m2mgsm.com/gps/mapatesty.php:459]

尝试使用带有Firebug扩展程序的Firefox或带有内置调试程序的Chrome来跟踪JavaScript代码并消除错误。
