javascript - Autozoom to fit markers on Google Maps V3

Question

I tried to follow instructions for autozoom on Google maps so that it always fits to the markers on the maps. But I can't get it to work. Can anyone see what's wrong with my code?

<script>

    function initMap() {
        var myLatLng = { lat: 55.561213987, lng: 8.1286275387 };

        var map = new google.maps.Map(document.getElementById('map-canvas'), {
            zoom: 13,
            center: myLatLng    
        });

        var marker = new google.maps.Marker({
            position: myLatLng,
            map: map,
            title: 'Top moderne sommerhus med alle faciliteter beliggende p? en sk?n grund med mange'
        });


        var marker = new google.maps.Marker({
            position: { lat: 55.5577227947, lng: 8.1225042121 },
            label: "1",
            map: map,
            title: 'L?kkert sommerhus beliggende p? en dejlig naturgrund'
        });

        var marker = new google.maps.Marker({
            position: { lat: 55.5570797278, lng: 8.1276749566 },
            label: "2",
            map: map,
            title: 'Sommerhus med str?tag beliggende p? en meget stor grund med mange fyrretr?er og '
        });

        var marker = new google.maps.Marker({
            position: { lat: 55.56169, lng: 8.13126 },
            label: "3",
            map: map,
            title: 'Dette sk?nne feriehus fremst?r utroligt flot'
        });

        var marker = new google.maps.Marker({
            position: { lat: 55.5560563333123, lng: 8.12075257301331 },
            label: "4",
            map: map,
            title: 'Sp?ndende, velholdt, str?t?kt feriehus i sten, beliggende p? delvis lukket natur'
        });

        var marker = new google.maps.Marker({
            position: { lat: 55.55282, lng: 8.12843 },
            label: "5",
            map: map,
            title: 'Kun 850 m fra Vesterhavet med den dejlige sandstrand og ca'
        });


        var map;
        var bound = new google.maps.LatLngBounds();
        var markers = new Array();

        //jQuery style entry point, change if necessary
        $(document).ready(function(){
          initMap();
          initMarkers();

          for(var i in markers)
          {
            bound.extend(markers[i].getPosition());
          }
          map.fitBounds(bound);
        });

        }
</script>

Any help will be much appreciated!

Answer 1

1. All your markers have the same name.
2. You don't ever put them in the markers array.
3. initMarkers doesn't exist.
