javascript - 检测滚动完成/结束

Question

我想检测用户何时停止滚动页面/元素。这可能很棘手，因为最近对 OSX 滚动行为的增强创造了这种新的惯性效应。是否触发了事件？

我能想到的唯一其他解决方案是在页面/元素的滚动位置不再改变时使用间隔来拾取，例如:

var element     = $( el );
var previous    = element.scrollLeft();
var current;

element.scroll( function(event)
{
    current = element.scrollLeft();

    if ( current === previous )
    {
        // user has stopped scrolling
    }

    previous    = current;
});

Answer 1

This可能有用。

// Setup isScrolling variable
var isScrolling;

// Listen for scroll events
window.addEventListener('scroll', function ( event ) {

    // Clear our timeout throughout the scroll
    window.clearTimeout( isScrolling );

    // Set a timeout to run after scrolling ends
    isScrolling = setTimeout(function() {

        // Run the callback
        console.log( 'Scrolling has stopped.' );

    }, 66);

}, false);
