[OpenLayers-Users] OpenLayers.Map + DOM Object - How to get Map Object from DOM Element

[Andreas Hocevar]

If you are referring to an OpenLayers.Map instance with "map object",
you won't find it in the DOM. You need to assign it a global variable
if you want that, e.g.

window.map = new OpenLayers.Map('worldmap');
