<h1>tiny jquery way</h1>

<pre><code>$.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));
  });
};
</code></pre>

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

<p><a href="http://jsfiddle.net/wtRrV/256/" rel="noreferrer">http://jsfiddle.net/wtRrV/256/</a></p>

<h3>lodash (even smaller)</h3>

<pre><code>function onScrollStopped(domElement, callback) {
  domElement.addEventListener('scroll', _.debounce(callback, 250));
}
</code></pre>

<p><a href="http://jsfiddle.net/hotw1o2j/" rel="noreferrer">http://jsfiddle.net/hotw1o2j/</a></p>

<h3>pure js (technically the smallest)</h3>

<pre><code>function onScrollStopped(domElement, callback, timeout = 250) {
  domElement.addEventListener('scroll', () =&gt; {
    clearTimeout(callback.timeout);
    callback.timeout = setTimeout(callback, timeout);
  });
}
</code></pre>

<p><a href="https://jsfiddle.net/kpsxdcv8/15/" rel="noreferrer">https://jsfiddle.net/kpsxdcv8/15/</a></p>

<h3>strange fact</h3>

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

<p>I prefer to be able to listen on a event. This is what I do:</p>

<p>The jquery plugin:</p>

<pre><code>+function(jQuery){
        var scrollStopEventEmitter = function(element, jQuery) {
            this.scrollTimeOut = false;
            this.element       = element;
            jQuery(element).on('scroll', $.proxy(this.onScroll, this));
        }

        scrollStopEventEmitter.prototype.onScroll = function() 
        {
            if (this.scrollTimeOut != false) {
              clearTimeout(this.scrollTimeOut);
            }

            var context = this;

            this.scrollTimeOut = setTimeout(function(){ context.onScrollStop()}, 250);
        }

        scrollStopEventEmitter.prototype.onScrollStop = function() 
        {
            this.element.trigger('scrollStop');
        }

        jQuery.fn.scrollStopEventEmitter = function(jQuery) {   
            return new scrollStopEventEmitter(this, jQuery);
        };

    }($);
</code></pre>

<p>In this case, window will now trigger scrollStop event</p>

<pre><code>$(window).scrollStopEventEmitter($);
</code></pre>

<p>Now I can listen on scrollStop</p>

<pre><code>$(window).on('scrollStop',function(){
        // code
</code></pre>


<p>If i want to bind an event on page scrolling i can use <code>scroll();</code>.</p>

<p>But how to fire when <code>scroll()</code> is ended up?</p>

<p>I would like to reproduce this:</p>

<pre><code>   $(window).scroll(function(){
    //do somenthing
    });

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

<p>any ideas?</p>
