We check which page is needed by calling upon a variable passed in through jQuery $_POST[‘page’]. or the Archives. Learn how to use JavaScript to add interactivity to websites. The common use of Ajax in web development has created a dynamic yet fluid Internet. Because the request is asynchronous, the rest of your code continues to execute while the request is being processed, so it’s imperative that a callback be used to handle the response. It’s just one little trick we can use for dynamically-loaded page results. url: “load-page.php”, We turn each array object inside the JSON string into a new variable called item.
