MarkerClusterer and infowindow

[Ross Ewing]

Hello all,

I'm having an issue getting a infowindow to open on a marker with the MarkerClusterer Google Map V3 API. Below is my code so far. Can anyone help?

    <script type="text/javascript">

function initialize() {

var center = new google.maps.LatLng(54.385756, -4.465256);

var map = new google.maps.Map(document.getElementById('map'), {

zoom: 5,

center: center,

mapTypeId: google.maps.MapTypeId.ROADMAP

});

var markers = [];

for (var i = 0; i < 100; i++) {

var dataPhoto = data.posts[i];

var latLng = new google.maps.LatLng(dataPhoto.latitude,

dataPhoto.longitude);

var marker = new google.maps.Marker({

position: latLng

});

markers.push(marker);

}

var markerCluster = new MarkerClusterer(map, markers);

var contentString = '<div id="content">'+

        '<div id="siteNotice">'+

        '</div>'+

        '<h1 id="firstHeading" class="firstHeading">Uluru</h1>'+

        '<div id="bodyContent">'+

        '<p><b>Uluru</b>, also referred to as <b>Ayers Rock</b>, is a large ' +

        'sandstone rock formation in the southern part of the '+

        '(last visited June 22, 2009).</p>'+

        '</div>'+

        '</div>';

        

var infowindow = new google.maps.InfoWindow({

content: contentString

});

google.maps.event.addDomListener(marker, 'click', function() {

      infowindow.open(map,marker);

    });

}

google.maps.event.addDomListener(window, 'load', initialize);

    </script>

Are you trying to set up a click event for a single marker? If so I believe the click event you are setting up would be for the last marker object you created in the preceding for loop.

Yeah so basically at the moment, i have a loop that reads from the
json file where the data is held. I'm looking to have a click event
when the user clicks a specific marker and for that to then show the
infowindow with the details of the marker.

Any help is much appreciated.

You need a helper function to create your markers, like the
createMarker() function in Larry's example* at
http://www.geocodezip.com/v3_MW_example_map1.html

If the data is kept together with a marker in a function, closure
ensures it's kept together.

The given example seems good but if you have many markers you may want to use a for loop to dynamically create your markers.
