Display loader while waiting for file to be loaded

I am utilizing ajax to retrieve a file. The loading animation is functioning properly with the ajax request, however, the file size is notably large. I am interested in implementing a preloader that will display until the file has finished loading.

Answer №1

To indicate that a process is starting, display a loading GIF. Once the process is completed, hide the GIF.

$('#loader_image').show();
$.ajax({
      ...
      complete: function(){
        $('#loader_image').hide();
      }
});

Answer №2

Make sure to include an element with a loading image (or any indication of waiting) and initially set its style to display: none. When the user clicks on a button to trigger an AJAX call, make sure to show this element.

$.ajax({
 url: "test.html",
context: document.body
}).done(function() {
$( this ).hide( ".loader" ); // This line will execute after the AJAX call is complete and hide the loader element 
});
