Adding AJAX Page Loading Effect To Blogger

Important: All scripts hosted on widcraft.googlecode.com don't work anymore because Google has blocked that SVN repository.

AJAX is not a new programming language, but a new way to use existing standards. AJAX is the art of exchanging data with a server, and updating parts of a web page - without reloading the whole page. AJAX was made popular in 2005 by Google, with Google Suggest.

Google Suggest is using AJAX to create a very dynamic web interface: When you start typing in Google's search box, a JavaScript sends the letters off to a server and the server returns a list of suggestions. Examples of applications using AJAX: Google Maps, Gmail, Youtube, and Facebook tabs

You can also use AJAX to create some beautiful loading effects on your blogger blog. Here we go:

  • Go To Blogger > Template > Edit HTML > Click on "Proceed"
  • Find and place following code below <body>:

<div id='loading'><div id='progress-bar'></div><div id='loader'>Loading...</div></div>

  • Now add following code just above </head>:

<script charset='utf-8' src='http://widcraft.googlecode.com/svn/jquery.min.js' type='text/javascript'></script>
<script>

(function($){

$("html").removeClass("v2");


$("#header").ready(function(){ $("#progress-bar").stop().animate({ width: "25%" },1500) });
$("#footer").ready(function(){ $("#progress-bar").stop().animate({ width: "75%" },1500) });


$(window).load(function(){

    $("#progress-bar").stop().animate({ width: "100%" },600,function(){
        $("#loading").fadeOut("fast",function(){ $(this).remove(); });
    });

});
})(jQuery);
</script>

<style>
#loading {
    position: fixed;
    z-index: 50;
    top: 0; left: 0;
    width: 100%; height: 100%;
 background: #3c5a76 url(https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh1-DMF_2ELaLMFFOFWGw5wA7hTFnRimVjuZ1NftTS5Ik3tem5nDd-GMA7v1sFxfpSMyptt6qhbEoWPtIM90BTsXn4gKHFxNxVj6nKy9WpFoK9H9on6L_Xa3y7tnuyAxoe4X7ZsiJr0Pvw/s1600/Loading.gif) no-repeat center;
    line-height: 350px;
    text-align: center;
    font-size: 36px;
    color: #353231;
    text-indent: -9999px;
}
.v2 #loading { display: none; }

#progress-bar {
    position: absolute;
    top: 0; left: 0;
    background: rgb(236, 133, 0);
    opacity: 0.8;
    width: 0;
    height: 18px;
}
#loader {
 background: url(https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEijoHdj8b4N4HYsdgZ5Xf8t7Cj51p8kBgOcplIV8Xse3bt2InhJi5Sidjhw-upO4DAfIce7QHeFAq-lWDBRfrBMxvpZYtj3crPvFXKQuU4hK5_gelnF1SAqe0667mph2Irnif15ensDcJE/s1600/BWidgets.png) no-repeat center 25%;
 height: 100%;
 display: block;
}
</style>
