Question

i’m using a moushweel plugin because i want my user to fire an action everytime it scroll up or down, but i dont want to have multiples fires (if you have a apple magic Mouse it is even worse because is too sensitive)

any idea on how to prevent it?

this is the code

jQuery(function($) {
    $('div.mousewheel_example')
        .bind('mousewheel', function(event, delta) {
            var dir = delta > 0 ? 'Up' : 'Down',
                vel = Math.abs(delta);
            $(this).text(dir + ' at a velocity of ' + vel);
            return false;
        });
});

this is the plugin page

You could try playing with window.setTimeout. Maybe by pulling out your nested function and using something a proxy function with a timer. Example:

var timer; 

function proxyFunction(){
  clearTimeout(timer);
  timer = setTimeout("mouseWheelAction", 1);
}

This will not stop the event firing but it will stop your function from running everytime the event fires.
