How to show div # loading while div #content loads

I want to implement a solution where:

  • while the content in div #content is loading,
  • hide div #content,
  • show div #loading,
  • after loading div #content,
  • hide div #loading,
  • fade in div #content

I tried:

HTML:

<div id="content">
<!--this stuff takes a long time to load-->
<img src="http://lorempixel.com/1920/1920/">
</div>
<div id="loading">
<!-- this is the loading gif -->
<img src="http://lorempixel.com/400/200/">
</div>

JS:

// when user browses to page
$('#content').hide();
$('#loading').show();

// then when div #content has loaded, hide div #loading and fade in div #content
$('#content').bind('load', function() {
$('#loading').hide();
$('#content').fadeIn('slow');
});

here is the jsfiddle I'm working on:

Thank you.

Take a div with class loader

CSS

.loader {

    position: fixed;
    left: 0px;
    top: 0px;
    width: 100%;
    height: 100%;
    z-index: 9999;
    background: url('images/loading.gif') 50% 50% no-repeat rgb(249,249,249);
    opacity: .7;
}

JS:

function myFunction() {

     $(".loader").show();

    Ajax Call({

//Ajax Call Operation

    success:function(result){

//Operation

}

complete: function(){

             $(".loader").fadeOut("slow");
          }
   });
