i tried this but it didn't work.

google.maps.event.addListener(map, "click", function(overlay,latlng) {
        if (latlng) {
        marker = new google.maps.Marker(latlng);
           google.maps.event.addListener(marker, "click", function() {
              var html = "<table>" +
                         "<tr><td>Name:</td> <td><input type='text' id='name'/> </td> </tr>" +
                         "<tr><td>Time:</td> <td><input type='text' id='time'/> </td> </tr>" +
                         "<tr><td>Bus Id:</td> <td><input type='text' id='busId'/> </td> </tr>" +
                         "<tr><td>Device Id:</td> <td><input type='text' id='deviceId'/> </td> </tr>" +
                         "<tr><td></td><td><input type='button' value='Save & Close' onclick='saveData()'/></td></tr>";
              marker.openInfoWindow(html);
            });
            map.setMap(marker);

         }
        });

Answer 1

You have to use event argument.

google.maps.event.addListener(map, 'click', function(event) {

    marker = new google.maps.Marker({position: event.latLng, map: map});

});

Answer 2

You have to use this.

 google.maps.event.addListener(map, 'click', function(event) {
    alert("Latitude: " + event.latLng.lat() + " " + ", longitude: " + event.latLng.lng());
  });
