How to Trigger Data Loading Precisely When a Specific Div Becomes Visible on Scroll with jQuery?

Precisely Controlling Data Loading on User Scroll with jQuery

In web development, implementing infinite scrolling is crucial for enhancing user experience by seamlessly loading additional data as users navigate through content. However, customizing this functionality to target specific elements on the page can pose a challenge.

In this case, the goal is to load more data only when a specific

with the class ".loading" becomes visible to the user on scroll. To achieve this, we can leverage jQuery's scrolling function to monitor the viewport and trigger data loading accordingly.

The heart of the solution lies in checking whether the scroll position has reached the bottom of the page. When the bottom is hit, an AJAX call can be made to retrieve the next set of data. This data is then appended to the designated loading

Here's how the jQuery code would look like:

$(window).scroll(function() {
    if($(window).scrollTop() == $(document).height() - $(window).height()) {
           // AJAX call to get data from server and append to the div
    }
});

Copy after login

This approach effectively ties data loading to the visibility of the loading

by leveraging the scroll event. As users scroll down the page, the script continuously checks the scroll position and initiates data loading whenever the

enters the viewport.
