Google Maps API Multiple Markers with Infowindows

Question

I am trying to add multiple markers each with its own infowindow that comes up when clicked on. I am having trouble with getting the infowindows coming up, when I try it either shows up only one marker without an infowindow.

Thanks, let me know if you need some more information

Use only ONE infowindow that is created before the markers. Then your click event for each marker will work correctly. The variable `content` inside your event listener is not defined within that function. — js1568, Jun 19 '12 at 18:03
Just as a quick comment, if you format your code well, it's a lot easier to read. — paullb, Jul 20 '17 at 13:54
@paullb I will reformat it, I wrote this question like 4 years ago when I was more of a novice :) — stacktraceyo, Jul 24 '17 at 19:09

You could use a closure. Just modify your code like this:

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

Here is the DEMO

I got this working but how would I change the code so that when I click on another marker it opens an infowindow which replaces the infowindow that was previously open, instead of continually opening more infowindows every time I click on another marker? – railsy May 10 '13 at 17:41
it works! but can somebody pls explain to me why is it working this way? – Lakshay Apr 06 '15 at 08:11

in this case, how should one close the infowindow when you click outside the map? – Rohit Tigga Mar 02 '16 at 06:54
How to close infowindow? `infowindow.close()` don't work. – mokiSRB Mar 03 '16 at 14:10
infoWindow **can be closed** simply by using a common variable: http://jsfiddle.net/ZFvDV/177/ – Manoj De Mel Dec 07 '17 at 00:28

The following code will show Multiple Markers with InfoWindow. You can Uncomment code to show Info on Hover as well

            var map;
            var InforObj = [];
            var centerCords = {

                lng: 131.036

            var markersOnMap = [{
                    placeName: "Australia (Uluru)",
                    LatLng: [{

                }

                }
            }

            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();
            }

A requirement for this solution is the use of const for infowindow and marker, else it doesn't work.. — Jim Jimson, Apr 27 '19 at 07:00

If you also want to bind closing of infowindow to some event, try something like this

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));

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);

 });

 }
}

Then move var infowindow = new google.maps.InfoWindow() to the initialize() function:

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` should be `google.maps.event.addListener` — Patrick Yan, May 04 '14 at 14:47
I get `TypeError: map.infowindow is undefined` if I include `var infowindow = new google.maps.InfoWindow();` inside of my initialize() function — invot, Jul 25 '14 at 18:58
