您可以为滚动事件添加事件处理程序并启动超时。类似于：

You can add an event handler for the scroll event and start a timeout. Something like:

var timer = null;
$(window).addEventListener('scroll', function() {
    if(timer !== null) {
        clearTimeout(timer);        
    }
    timer = setTimeout(function() {
          // do something
    }, 150);
}, false);

这将开始超时并等待150ms。如果在此期间发生新的滚动事件，则中止计时器并创建一个新计时器。如果不是，则执行该功能。您可能需要调整时间。

This will start a timeout and wait 150ms. If a new scroll event occurred in the meantime, the timer is aborted and a new one is created. If not, the function will be executed. You probably have to adjust the timing.

还要注意IE使用不同的方式来附加事件监听器，这应该给出一个很好的介绍： quirksmode - 高级活动注册模型

Also note that IE uses a different way to attach event listeners, this should give a good introduction: quirksmode - Advanced event registration models
