如何检测角度材质自动补全组件中的滚动位置

window.addEventListener('scroll', function() {
    const scrollTop = window.pageYOffset || document.documentElement.scrollTop;
    console.log('Window Scroll Top:', scrollTop);
});

const element = document.getElementById('your-element-id');
element.addEventListener('scroll', function() {
    const scrollTop = element.scrollTop;
    console.log('Element Scroll Top:', scrollTop);
});

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

window.addEventListener('scroll', throttle(function() {
    const scrollTop = window.pageYOffset || document.documentElement.scrollTop;
    console.log('Window Scroll Top:', scrollTop);
}, 100));

const element = document.getElementById('your-element-id');
element.addEventListener('scroll', function() {
    const rect = element.getBoundingClientRect();
    const scrollTop = rect.top + window.pageYOffset;
    console.log('Element Scroll Top:', scrollTop);
});
