答案 0 :(得分：1)
即使您只在一个元素上设置$('.markets-item:not(.active):last').one(animatedend)，它也会被多次触发。这可能是因为animatedend代表了一系列事件：
webkitAnimationEnd mozAnimationEnd MSAnimationEnd oanimationend animationend
如果您在this modified fiddle中查看控制台，您会看到我设置的notActivedItemsCount低于零。这意味着$('.markets-item:not(.active):last').one(animatedend)被调用次数超过它应该的次数。
你在同一个代码块中确实有.animate()，所以不清楚是否会导致竞争条件，因为我们无法保证$('.markets-item:not(.active):last') - 列表中的最后一个元素 - 也是完成动画的最后一个元素。
在此second modified fiddle中，我添加了
notActivedItems.unbind(animatedend);
在.one(animatedend, function() {块内，这将保证此代码块只执行一次。
