我正在忙着一个脚本,它会在我的网站上制作一个带有多个标记的谷歌地图画布.我希望当你点击一个标记时,会打开一个信息窗口.我已经这样做了,代码就是这样:

 var latlng = new google.maps.LatLng(-34.397, 150.644);
    var myOptions = {
      zoom: 8,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
    function addMarker(map, address, title) {
     geocoder = new google.maps.Geocoder();
     geocoder.geocode( { 'address': address}, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
          map.setCenter(results[0].geometry.location);
          var marker = new google.maps.Marker({
     position: results[0].geometry.location,
              map: map,
              title:title
    });
    google.maps.event.addListener(marker, 'click', function() {
     var infowindow = new google.maps.InfoWindow();
            infowindow.setContent('<strong>'+title + '</strong><br />' + address);
             infowindow.open(map, marker);

          });
        } else {
          alert("Geocode was …

我有InfoWindow的问题.我有一个通过JSON检索数据的ajax函数,但是当你打开另一个时我无法自动关闭InfoWindow.我的代码是这样的:

var mapOptions = {
    center: new google.maps.LatLng(44.49423583832911, 11.346244544982937),
    zoom: 13,
    mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById("mappa_locali"),mapOptions);
$.ajax({
    type:'GET',
    url:"locali_json.php"+urlz,
    success:function(data){ 
          var json = JSON.parse(data);
          for (var i=0; i<json.length; i++) {
             point = new google.maps.LatLng(json[i].latitudine,json[i].longitudine);
             var infowindow = new google.maps.InfoWindow;
             infowindow.setContent('<a href="./dettaglioLocale.php?id_loc='+json[i].id_locale+'">'+json[i].nome_locale+'</a><br>'+json[i].address);
             addMarkerz(point,infowindow);
          }
    }
})
 }


   function addMarkerz(point,infowindow) { 
    position: point,
    map: map
   });
    google.maps.event.addListener(marker,'mouseover',infoCallback(infowindow, marker));
    markers.push(marker);
    infos.push(infowindow);
     }

    function infoCallback(infowindow, marker) { 
      return function() {
         infowindow.close();  
        infowindow.open(map, marker);

      };
    }

有谁知道哪里减少了错误？或者你对我有什么建议吗？
