Question

我想出了如何使用信息窗口有多个标记但是当你点击另一个标记时它们没有关闭，我相信这是因为我正在为每个标记创建一个新的信息窗口，任何帮助都将不胜感激。

    <script type="text/javascript">


var map ;
  function initialize() {
    var latlng = new google.maps.LatLng(53.063165, -3.205390);
    var myOptions = {
      zoom: 6,
      center: latlng,
      mapTypeId: google.maps.MapTypeId.SATELLITE,
      zoomControl: false,
      mapTypeControl: false,
      mapTypeControlOptions: {
          style: google.maps.MapTypeControlStyle.DROPDOWN_MENU,
          position: google.maps.ControlPosition.LEFT_CENTER
      },
panControl: false,
streetViewControl: false,
      streetViewControlOptions: {
          position: google.maps.ControlPosition.LEFT_CENTER
      }
};
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

  var marker = add_marker(56.747923,-3.717155,"Ben Vrackie","<b>Ben Vrackie</b><br><br>Perthshire classic! some sweet hidden gems on this loop.<br> surrounded by amazing countryside, Lochs, hills this<br>has it all... Red Grade."); // pass in as Latitude, then Longitude
    marker.setMap(map);

   var marker = add_marker(57.556366,-5.409222,"Torridon Forest","<b>Torridon Forest</b><br><br>Technical and breathtaking.... <br>Black/red grade."); // pass in as Latitude, then Longitude
    marker.setMap(map)
}


  function add_marker(lat,lng,title,box_html) {

    var infowindow = new google.maps.InfoWindow({
        content: box_html
    });

    var marker = new google.maps.Marker({
          position: new google.maps.LatLng(lat,lng),
          map: map,
          title: title
    });


    google.maps.event.addListener(marker, 'click', function() {
        infowindow.open(map,marker);
});
return marker;
  }



 </script>

Answer 1

仅创建一个全局InfoWindow对象。

 //Global 
  var infowindow = new google.maps.InfoWindow();

然后

    function add_marker(lat,lng,title,box_html) {

        var marker = new google.maps.Marker({
              position: new google.maps.LatLng(lat,lng),
              map: map,
              title: title
        });

  google.maps.event.addListener(marker, 'click', function() {
        infowindow.setContent(box_html);

        infowindow.open(map,marker);
    });
    return marker;
  }

Answer 2

更改add_marker函数以使用单个全局infowindow。一种方式：

var infowindow = null;
function add_marker(lat,lng,title,box_html) {

  infowindow = new google.maps.InfoWindow({
      content: box_html
  });

  var marker = new google.maps.Marker({
      position: new google.maps.LatLng(lat,lng),
      map: map,
      title: title
  });

  google.maps.event.addListener(marker, 'click', function() {
      infowindow.setContent(box_html);
      infowindow.open(map,marker);
  });
  return marker;
}
