What zoom level are you viewing at? myMap.map.map_3.getLatLon(myPoint) assumes you are on zoom level 3. Example:

myMap.map.map_%.getLatLon(myPoint)

where % = current map level.

Note that this is undocumented and not part of the offcial “API”, but it works.

I hope that helps.

This is great… except I’m getting an undefined (when I execute the click) LatLon (yes I’m importing the com.yahoo.maps.LatLon) on the myMap.map.map_3.getLatLon(myPoint)?

I am getting x,y values from the previous call new Point(myMap._xmouse, myMap._ymouse)

Any Ideas?

Sorry Andrew. I don’t know.

Is it possible to use this technique in combination with a CustomSWFOverlay when using the JS-Flash API? I’m trying to find a way to allow users to click on a map, automatically creating a marker, returning the lat/lon. Any ideas how to accomplish this?

Great idea! Yes you can dynamically assign the map like this:

var latLon:LatLon = yahooMap.map["map_" + zoom].getLatLon(mapPoint);

Zoom is a variable where you are keeping track of the zoom level.

Yes, this is an undocumented call. Does this answer your question?

thanks for posting the source code! I’m slighty new to the ymap as business, and I was wondering if you could tell me what the line:

var latLon:LatLon = yahooMap.map.map_3.getLatLon(mapPoint);

is doing. is there a way to change the map_3 parameter dynamically to allow for this to work at various zoom levels? Is the getLatLon method an unexposed part of the api? Thanks for any help, and keep up the sweet work… will
