How to set a popup on markers with Google Maps API?

Question

I have this code where I display and set all my markers. How can I add a popup with some information on markers with this code? I add \"i\" variable on text, but it sets on all

Answer 1

this is the area where you can add your content of popup

var infowindow = new google.maps.InfoWindow({
                content: "Add your popup content here"
              });

and this is for showing your popup

marker.addListener('click', function() {
          infowindow.open(map, marker);
        });

Below code shows how its work and use.

features.forEach(function(feature) {
          var infowindow = new google.maps.InfoWindow({
                    content: "Add your popup content here"
                  });
            var marker = new google.maps.Marker({
            position: new google.maps.LatLng(lat,long),
            icon: "image.png",
            /*icon: icons[feature.type].icon,*/
            title: "Title for marker",
            map: map
          });
          marker.addListener('click', function() {
          infowindow.open(map, marker);
        });
        });
