    <div id="mapContainer"  style="width: 640px; height: 400px;"></div>
<script type="text/javascript">
    var map0 = new TMap(mapContainer, 25.7590256665386, -80.3738769902151, 15, mapLoaded, 1, true, "", "hybrid");
   
    function mapLoaded() {
        map0.SetOnDoubleClickListener(MapDoubleClicked);
    }
    function MapDoubleClicked(lat,lon){
        var boundary = map0.GetBounds();
            var tab0 = new TTabObject("Center", "Latitude=\t" + lat + "\nLongitude=\t" + lon);
            var tab1 = new TTabObject("Four Borders",
                                      "Top\t= "+boundary.latitude1+"\nButtom\t= "+boundary.latitude2+
                                      "\nLeft \t= "+boundary.longitude1+"\nRight\t= "+boundary.longitude2);
            var tabArray = new Array ();
            tabArray[0] = tab0;
            tabArray[1] = tab1;
