Question

我正在尝试添加多个标记，每个标记都有自己的infowindow，点击时会出现。当我尝试让它出现时，我遇到了麻烦，当我尝试它时，它只显示一个没有信息的标记。

谢谢，如果您需要更多信息，请与我们联系

Answer 1

你可以使用一个闭包。只需像这样修改你的代码：

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

以下是可行的代码片段。您可以访问link下面的工作jsFiddle并详细解释。 How to locate multiple addresses on google maps with perfect zoom

var infowindow = new google.maps.InfoWindow();  
google.maps.event.addListener(marker, 'mouseover', (function(marker) {  
           return function() {  
               var content = address;  
               infowindow.setContent(content);  
               infowindow.open(map, marker);  
           }  
         })(marker));

Answer 3

如果你还想将infowindow的关闭绑定到某个事件，请尝试这样的事情

=INDEX(AF:AF,MATCH(P930,Q:Q,0))

以下代码将显示带有InfoWindow的多个标记。您也可以取消注释代码，以同时在悬停上显示信息

            var map;
            var InforObj = [];
            var centerCords = {
                lat: -25.344,
                lng: 131.036
            };
            var markersOnMap = [{
                    placeName: "Australia (Uluru)",
                    LatLng: [{
                        lat: -25.344,
                        lng: 131.036
                    }]
                },
                {
                    placeName: "Australia (Melbourne)",
                    LatLng: [{
                        lat: -37.852086,
                        lng: 504.985963
                    }]
                },
                {
                    placeName: "Australia (Canberra)",
                    LatLng: [{
                        lat: -35.299085,
                        lng: 509.109615
                    }]
                },
                {
                    placeName: "Australia (Gold Coast)",
                    LatLng: [{

                        lng: 513.425586
                    }]
                },
                {
                    placeName: "Australia (Perth)",
                    LatLng: [{
                        lat: -31.951994,

                    }]
                }
            ];

            window.onload = function () {
                initMap();
            };

            function addMarkerInfo() {
                for (var i = 0; i < markersOnMap.length; i++) {
                    var contentString = '<div id="content"><h1>' + markersOnMap[i].placeName +
                        '</h1><p>Lorem ipsum dolor sit amet, vix mutat posse suscipit id, vel ea tantas omittam detraxit.</p></div>';

                    const marker = new google.maps.Marker({
                        position: markersOnMap[i].LatLng[0],
                        map: map
                    });

                    const infowindow = new google.maps.InfoWindow({
                        content: contentString,
                        maxWidth: 200
                    });

                    marker.addListener('click', function () {
                        closeOtherInfo();
                        infowindow.open(marker.get('map'), marker);
                        InforObj[0] = infowindow;
                    });
                    // marker.addListener('mouseover', function () {
                    //     closeOtherInfo();
                    //     infowindow.open(marker.get('map'), marker);
                    //     InforObj[0] = infowindow;
                    // });
                    // marker.addListener('mouseout', function () {
                    //     closeOtherInfo();
                    //     infowindow.close();
                    //     InforObj[0] = infowindow;
                    // });
                }
            }

            function closeOtherInfo() {
                if (InforObj.length > 0) {
                    InforObj[0].set("marker", null);
                    InforObj[0].close();
                    InforObj.length = 0;
                }
            }

            function initMap() {
                map = new google.maps.Map(document.getElementById('map'), {
                    zoom: 4,
                    center: centerCords
                });
                addMarkerInfo();
            }

Answer 5

function setMarkers(map,locations){

for (var i = 0; i < locations.length; i++)
 {  

 var loan = locations[i][0];
 var lat = locations[i][1];
 var long = locations[i][2];
 var add =  locations[i][3];

 latlngset = new google.maps.LatLng(lat, long);

 var marker = new google.maps.Marker({  
          map: map, title: loan , position: latlngset  
 });
 map.setCenter(marker.getPosition());


 marker.content = "<h3>Loan Number: " + loan +  '</h3>' + "Address: " + add;


 google.maps.events.addListener(marker,'click', function(map,marker){
          map.infowindow.setContent(marker.content);
          map.infowindow.open(map,marker);

 });

 }
}

然后将var infowindow = new google.maps.InfoWindow()移至initialize()函数：

function initialize() {

    var myOptions = {
      center: new google.maps.LatLng(33.890542, 151.274856),
      zoom: 8,
      mapTypeId: google.maps.MapTypeId.ROADMAP

    };
    var map = new google.maps.Map(document.getElementById("default"),
        myOptions);
    map.infowindow = new google.maps.InfoWindow();

    setMarkers(map,locations)

  }

带有Infowindows的Google Maps API多个标记
