Cancel all queued jQuery slideUp and slideDown animations

Question

I have an interface that makes heavy use of the jQuery slideUp and slideDown effect to expand items in a tri-state kind of way.

onmouseover: function() { 
this.find('.details', this).slideDown(); 
},
onmouseout: function() { 
this.find('.details', this).slideUp(); 
}

However, when the user quickly moves the mouse over these interface elements the animations can't keep up and the items will be sliding up and down long after the mouse has left the interface area.

Is there a way to cancel all the queued-up slide animations when the mouse leaves the item's container div?

Answer 1

I believe you should be able to just add a .stop() and it'll take care of that for you:

onmouseover: function() { 
this.find('.details', this).stop().slideDown(); 
},
onmouseout: function() { 
this.find('.details', this).stop().slideUp(); 
}

Answer 2

The answer you really want is a combination of all the other three answers.

$("...").hover(function() {
  $(this).stop(true, true).slideDown();
}, function() {
  $(this).stop(true, true).slideUp();
});

You want the trues in the stop because these clear the pending animation queues. If you dont use these, you'll find moving the mouse quickly and repeatedly across the element will produce buggy results.
