done=1;
}

Just off the top of my head after I haven't used it for a while - so there are probably much better solutions out there! |
Be aware of a problem here that often catches out people new to JavaScript and other similar languages for that matter.
The variable you are setting, 'done' only exists inside the function, so once the function finishes, so the variable 'done' no longer exists. You would need to define the variable globally.
