Here are some simple debouncing examples, utilizing doTimeout. For more usage examples, also see the doTimeout plugin page.

Typing into a textfield (250ms delay)

var default_text = $('#text-type').text();

$('form input').keyup(function(){
  $(this).doTimeout( 'text-type', 250, function(){
    $('#text-type').text( this.val() || default_text );
  });
});

Go ahead, type!

Window resize (some browsers fire this event continually)

$(window).resize(function(){
  $.doTimeout( 'resize', 250, function(){
    // do something computationally expensive
  });
});

Window scroll (most browsers fire this event continually)

$(window).scroll(function(){
  $.doTimeout( 'scroll', 250, function(){
    // do something computationally expensive
  });
});
