I am trying to know how to use the createPolygon function in the parser options.

This is my index file but it gives me this error: Cannot read property 'bounds' of undefined.

var geoXml="", map="";
var infowindow = new google.maps.InfoWindow({});

function initialize() {
    var myOptions = {
        center: new google.maps.LatLng(39.397, -100.644),
        zoom: 4,
        mapTypeId: google.maps.MapTypeId.ROADMAP
    };
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);

    geoXml = new geoXML3.parser({
        map: map,
        zoom: true,
        createMarker: addMyMarker,
        createPolygon: addMyPolygon,
        singleInfoWindow: true,
        suppressInfoWindows: true
    });

    geoXml.parse('testPolygon.xml');

    function addMyMarker(placemark) {
        var marker = geoXml.createMarker(placemark);
            //marker.setAnimation(google.maps.Animation.BOUNCE);
            google.maps.event.addListener(marker, 'click', function() {
                infowindow.setContent(placemark.description);   
                infowindow.setPosition(marker.getPosition());
                infowindow.open(map,marker);
            });
        };

        function addMyPolygon(placemark) {
            var polygon = geoXml.createPolygon(placemark);
            google.maps.event.addListener(polygon, 'click', function() {
                infowindow.setContent(placemark.description);   
                var lat = event.latLng.lat();
                var lng = event.latLng.lng();
                var myLatlng = new google.maps.LatLng(lat,lng);
                infowindow.setPosition(myLatlng);
                infowindow.open(map,polygon);
            });
        };

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

</script>
</body>
</html>

I want to know if is correct the way I'm using the 'createPolygon:addMyPolygon' function, or where is the issue, I mean how can I set a click Listener for each polygon using the createPolygon function. I did it with the createMarker function for a KML with markers, but in the file above the createPolygon doesn't parse my KML file.

My KML/XML file is: http://www.geocodezip.com/geoxml3_test/testPolygon.xml

createPolygon 函数需要将生成的多边形返回给 GeoXml3，以便对其进行管理。

function addMyPolygon(placemark) {
    var polygon = geoXml.createPolygon(placemark);
    google.maps.event.addListener(polygon, 'click', function(event) {
        var myLatlng = event.latLng;
        infowindow.setContent("<b>"+placemark.name+"</b><br>"+placemark.description+"<br>"+event.latLng.toUrlValue(6));   
        infowindow.setPosition(myLatlng);
        infowindow.open(map);
    });
    return polygon;
};

此外，如果您要event在多边形“点击”侦听器中使用它，则需要对其进行定义。

工作示例
