Google地圖2 InfoWindow自動打開infoWindow，1點擊後的infoWindow

Question

我有一個自動打開的infoWindow。

我希望只有兩個自動打開，而一個沒有。效果就像在圖片中。 我的代碼：

<script> 
function initialize() { 
    var openedInfoWindow = []; 
    var locations = [ 
     ['Oddział', 52.846190, 17.723237, 3], 
     ['Oddział', 52.812224, 17.201023, 2], 
     ['Zakład Poligraficzny - Siedziba', 52.847942, 17.757889, 1]  
    ]; 
    var cityCircle; 
    var map = new google.maps.Map(document.getElementById('map-canvas'), { 
     mapTypeId: google.maps.MapTypeId.ROADMAP, 
     zoomControl: true, 
      zoomControlOptions: { 
      style: google.maps.ZoomControlStyle.SMALL 
      } 

    }); 

    var bounds = new google.maps.LatLngBounds(); 

    for (i = 0; i < locations.length; i++) { 
     var marker = new google.maps.Marker({ 
      position: new google.maps.LatLng(locations[i][1], locations[i][2], locations[i][3]), 
      map: map, 
      content: locations[i][0] 
     }); 

     bounds.extend(marker.position); 

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

     google.maps.event.addListener(marker, 'click', (function(marker, i, infowindow) { 
      return function() { 

       if(openedInfoWindow[i] != null){        
        openedInfoWindow[i].close(); 
        openedInfoWindow[i] = null; 
       }else{     
        infowindow.setContent(this.content); 
        infowindow.open(map, this); 
        openedInfoWindow[i] = infowindow; 
        google.maps.event.addListener(infowindow, 'closeclick', function() { 
         openedInfoWindow[i] = null;       
        }); 
       } 
      }    
     })(marker, i, infowindow));   

     google.maps.event.trigger(marker, 'click'); 
    } 

    map.fitBounds(bounds); 

    var listener = google.maps.event.addListener(map, "idle", function() { 
     map.setZoom(9); 
     google.maps.event.removeListener(listener); 
    }); 
} 
function loadScript() { 
    var script = document.createElement('script'); 
    script.src = 'https://maps.googleapis.com/maps/api/js?key=AIzaSyADTnbl7e9y2o13cXkUFO8RZpXFJI-yzp4&' + 'callback=initialize'; 
    document.body.appendChild(script); 
} 

window.onload = loadScript; 
</script>` 

Picture 1 = so now

Picture 2 = so it has to be

Answer 1

我建議你概括它，一個成員添加到您的陣列，以確定是否打開標記與否。

var locations = [ 
    // IW content, lat, lng, nowrap, open IW 
    ['Oddział', 52.846190, 17.723237, 3, true], 
    ['Oddział', 52.812224, 17.201023, 2, true], 
    ['Zakład Poligraficzny - Siedziba', 52.847942, 17.757889, 1, false]  
]; 

然後做到這一點，打開信息窗口：

if (locations[i][4]) { 
    google.maps.event.trigger(marker, 'click'); 
}
