let isLoading = false; // Prevent duplicate requests

window.addEventListener('scroll', () => {
 const scrollPosition = window.innerHeight + window.scrollY;
 const documentHeight = document.body.offsetHeight;

 if (scrollPosition >= documentHeight - 200 && !isLoading) {
 loadMoreContent();
 }
});

async function loadMoreContent() {
 isLoading = true;
 loadingIndicator.style.display = 'block';

 try {
 // Simulate fetching new content from server
 const newItem = document.createElement('div');
 newItem.className = 'item';
 newItem.textContent = `New item loaded at ${new Date().toLocaleTimeString()}`;

 const el = document.createElement('div');
 el.className = 'item';
 el.textContent = item.title;
 contentDiv.appendChild(el);
 });

 // If the server indicates no more data, disable loading
 if (data.is_last_page) hasMoreContent = false;
 } catch (error) {
