Hi, Here's the problem - I know function by name (and that function has already been loaded form an external script), but I don't have an actual function object avail for me to call. Normally I would call eval(function_name + "(arg1, arg2)"), but in my case I need to pass an object to it, not a string. Simple example: var div = docume...
