Google Maps is great, but some hacks are needed
I’m currently working on an AJAX-driven site also using Google Maps’ externally accessible API. But I have as several others been frustrated about the fact, that the GMarkerManager-class does not contain a clearMarkers method. So I combined the open-sourced source with the latest closed-source release, and mashed stuff up like this:
// hack GMarkerManager to contain a method for clearing all markers GMarkerManager.prototype.clearMarkers = function() { var me = this; // // clear currently shown if (me.Wd > 0) { me.Id(me.K, me.Kd); } // // reset arrays var maxZoom = me.df; var maxWidth = 256; for (var zoom = 0; zoom < maxZoom; ++zoom){ me.ed[zoom] = []; me.oc[zoom] = 0; me.gc[zoom] = Math.ceil(maxWidth/me.Ec); maxWidth <<= 1; } me.refresh(); }
It is “hardcoded” to version 2.76 and will need to be changed for later versions of the API, but for now it must do :)
