js滚动条监听事件

window.addEventListener('scroll', function() {
    console.log('Scroll Position:', window.scrollY);
});

var element = document.getElementById('scrollableElement');
element.addEventListener('scroll', function() {
    console.log('Element Scroll Position:', element.scrollTop);
});

function throttle(func, wait) {
    let timeout = null;
    return function() {
        if (!timeout) {
            timeout = setTimeout(() => {
                func.apply(this, arguments);
                timeout = null;
            }, wait);
        }
    };
}

window.addEventListener('scroll', throttle(function() {
    console.log('Scroll Position:', window.scrollY);
}, 100)); // 每100毫秒最多触发一次

if ('onscroll' in window) {
    // 浏览器支持scroll事件
}
