call JavaScript function within Google Maps Listener

Question

Ok, simple question but is it possible to call an external javascript function within a google maps listener?

GEvent.addListener(map,"click", function(overlay, latlng) {
 testfunction(latlng);
});

testfunction doesn't run, so is there a particular way i need to go about this? I'm new to google maps and javascript.

Answer 1

Of course it is possible. Otherwise it would be useless. Try to include your funnction definition within the same script tag and check if it works.

Answer 2

Try your listener handler function with one parameter at first: a GLatLng object that corresponds to the latitude/longitude where the user clicked on the map.

Give this a try initially:

GEvent.addListener(map, "click", function(latlng) {
    testfunction(latlng);
});

If that doesn't work, ensure that your testfunction is handling the GLatLng type properly (using the object's properties correctly, etc.).
