带有Infowindows的Google Maps API多个标记


91

我试图添加多个标记,每个标记都有其自己的信息窗口,这些标记会在单击时出现。我在启动信息窗口时遇到麻烦,当我尝试它时,只显示一个标记而没有信息窗口。

谢谢,让我知道您是否需要更多信息

仅使用在标记之前创建的一个信息窗口。然后,每个标记的点击事件将正常运行。content您的事件监听器中的变量未在该函数中定义。

就像快速评论一样,如果您正确地格式化代码,那么它会更容易阅读。

@paullb我将重新格式化它,我在4年前还是个新手的时候就写了这个问题:)

您可以使用闭包。像这样修改您的代码:

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

这是演示

我已经开始工作了,但是我将如何更改代码,以便当我单击另一个标记时,它会打开一个信息窗口来替换以前打开的信息窗口,而不是每次单击另一个标记时都会不断打开更多的信息窗口?

有用!但是有人可以向我解释为什么这样工作吗?

这是肯定会起作用的代码段。您可以访问下面的链接,详细了解jsFiddle和explaitantion的工作方式。 如何完美缩放在Google地图上定位多个地址

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

                        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;
                    });

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

            function closeOtherInfo() {

                    InforObj[0].set("marker", null);

                }
            }

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

对于此解决方案的要求是信息窗口和标志使用const,否则它不工作..

如果您还想将关闭信息窗口绑定到某个事件,请尝试这样的操作

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

0
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);

 });

 }
}

然后移动var infowindow = new google.maps.InfoWindow()initialize()功能:

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)

  }

google.maps.events.AddListener应该是google.maps.event.addListener

TypeError: map.infowindow is undefined如果我将其包含var infowindow = new google.maps.InfoWindow();在initialize()函数中
则会
