在url javascript中滚动时更改分页号

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

window.addEventListener('scroll', throttle(handleScroll, 200));

function updatePaginationInURL(pageNumber) {
    const url = new URL(window.location.href);
    url.searchParams.set('page', pageNumber);
    window.history.pushState({}, '', url);
}

function handleScroll() {
    if (window.innerHeight + window.scrollY >= document.body.offsetHeight - 500) {
        const currentPage = parseInt(new URL(window.location.href).searchParams.get('page')) || 1;
        updatePaginationInURL(currentPage + 1);
        // 加载更多内容的逻辑
    }
}
