Couldn't find a clean way to do it so my approach is to pass in a third variable ( array or pointer ) then modify eve.once to assign f2 to that variable, so i can unsub with eve.off("evt", f2).
eve.once = function (name, f, unbinder) {
var f2 = function () {
eve.unbind(name, f2);
return f.apply(this, arguments);
};
if(unbinder) unbinder.push(f2);
return eve.on(name, f2);
};
It's absolutely ugly but does the job for now. Does anyone have a cleaner way to implement ?
