相反,我建议使用间隔,你可以调整每个间隔之间的时间到对你的用例感觉良好的时间.

尽管在使用滚动事件时每隔X毫秒触发此逻辑可能看起来非常密集,但您可能会每秒触发事件数百次,这对于使用具有限制处理的设备的用户来说将更加密集和明显.功率.

(function () {
     var interval = null,//Currently set at 0.4 seconds,play with the code
         //and change this value to see what works best for 
         //this use-case
         time_between_interval = 400;

     setInterval(scrollLogic,time_between_interval); 

     function scrollLogic () {
         //The function body of what you're assigning 
         //to the scroll event.
     } 

     //I have omitted clearing the interval but you would want to do that,perhaps on page change,or something.

     //clearInterval(interval);
})();
