Hi, The challenge is that I do not get the markers onto the map. I'm searching the webb but without any luck.
This is what I would like to achieve: http://gmaps-utility-library.googlecode.com/svn/trunk/markerclusterer/1.0/examples/simple_example.html My problem is that I do not know what's the problem with the code and if I have known the problem I would have solved it...:-) I *think* there are some issues with the way the markers are iterated through in the for-loop and in the way the are printed on the screen...or rather...how they should be printed on the screen. So...I'm stuck and would be sooo greatful if someone can "unstuck" me :-)) /Nimrod On 14 Maj, 20:10, "[email protected]" <[email protected]> wrote: > On May 14, 10:51 am,nimrod<[email protected]> wrote:> OK, you > find the page at > > http://www.g8journey.com/destinations/destinations_main.php > > > > > I have markerCluster = new MarkerClusterer(map, markersXml); in the > > function that process the response from the GDownloadUrl and var > > markerCluster; on top and outside all functions. > > And? > - what is the problem? > - did you answer this question? > > > > > > var markersXml = []; > > Why are you emptying the markersXml array that you just created?
