Good point. How about...
var counter = {};
$().click(function(event) {
if(!counter[this])
counter[this] = 0;
if(counter[this]++ == 5)
$(this).unbind(event);
});
That, on the other hand, would be worth adding to jQuery core. We could
still rename one() to bindN() with a max count of 1 as default, eg.
bindN("click", 5, myHandler)
If you think this makes sense, please report it as a feature requests.
