How to Load More Data on Scroll Only When a Specific Div is Visible?

jQuery: Load More Data on Scroll

Understanding how to implement the loading of additional data as soon as a specific div (.loading) becomes visible can be a valuable technique. In this scenario, there are multiple .loading divs within a drop-down box, and the task is to initiate data loading solely for the currently visible div.

To determine whether a .loading div is visible, jQuery offers a reliable solution. By utilizing the scroll function, you can monitor the user's scroll position and determine when they reach the bottom of a page.

Here's how it works:

1. Implement a Scroll Event Listener:

   $(window).scroll(function() {
       // Your code here
   });

2. Check for Reaching the End:

   if($(window).scrollTop() == $(document).height() - $(window).height()) {
       // Fetch and Append New Data
   }

3. Fetch and Append New Data (inside the if statement):

   // Make an AJAX call to retrieve new data
   // Append the retrieved data to the visible .loading div

By implementing this technique, you can effectively load more data only when a specific .loading div becomes visible during scrolling, ensuring a seamless and responsive user experience.
