If your logger doesn't use any asynchronous code, then putting it in a domready (or simply after the init script) will ensure the logger is ready by the time you call it.
BUT if you do have async code in it, then firing the event on the window is a solid way of achieving this On Mon, Jul 25, 2011 at 2:05 PM, Paul Schwarz <[email protected]>wrote: > domready seems to be the event that you'll see in bootstrap code of > anything written for mootools. > > A few times now I've come across cases where, on top of Mootools, I > build another mini-framework.
