jQuery - 滚动停止时绑定事件 [英] jQuery - bind event on Scroll Stop

问题描述

如果我想在页面滚动时绑定一个事件，我可以使用 scroll();.

If i want to bind an event on page scrolling i can use scroll();.

但是如何在 scroll() 结束时触发?

But how to fire when scroll() is ended up?

我想重现这个:

   $(window).scroll(function(){
    //do somenthing
    });

    $(window).scrollSTOPPED(function(){  //--> when i'm scrolling then i stop to scrolling (so NOT when page scrollbar is at the end top or bottom :)
    //do somenthing else
    });

有什么想法吗?

推荐答案

jquery 的小方法

$.fn.scrollStopped = function(callback) {
  var that = this, $this = $(that);
  $this.scroll(function(ev) {
    clearTimeout($this.data('scrollTimeout'));
    $this.data('scrollTimeout', setTimeout(callback.bind(that), 250, ev));
  });
};

在距离最后一个滚动事件 250 毫秒后，这将调用scrollStopped"回调.

After 250 ms from the last scroll event, this will invoke the "scrollStopped" callback.

function onScrollStopped(domElement, callback) {
  domElement.addEventListener('scroll', _.debounce(callback, 250));
}

function onScrollStopped(domElement, callback, timeout = 250) {
  domElement.addEventListener('scroll', () => {
    clearTimeout(callback.timeout);
    callback.timeout = setTimeout(callback, timeout);
  });
}

clearTimeout 和 clearInterval 参数不必定义，甚至可以是错误类型甚至省略.

clearTimeout and clearInterval params don't have to be defined and can even be wrong types or even omitted.
