PreLoadMe is a lightweight preloader for any webcontent. Powered by jQuery and CSS it is fully responsive and will run on all modern desktop- and mobile browsers with no additionals plugins. PreLoadMe displays a loading animation until the browser fetched the whole webcontent and will fade out the moment the page has been completely chached. Because the simplicity of PreLoadMe, it can be easily customized and adapted to your needs.
PreLoadMe needs following components to work:
You need jQuery to run PreLoadMe. Add this code before the </body> tag.
<!-- jQuery Plugin -->
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6/jquery.min.js"></script>
Place the following JavaScript code right before the </body> tag.
<!-- Preloader -->
<script type="text/javascript">
//<![CDATA[
$(window).load(function() { // makes sure the whole site is loaded
$('#status').fadeOut(); // will first fade out the loading animation
$('#preloader').delay(350).fadeOut('slow'); // will fade out the white DIV that covers the website.
$('body').delay(350).css({'overflow':'visible'});
})
//]]>
</script>
Make sure you include the following CSS code on your website.
body {
overflow: hidden;
}
/* Preloader */
#preloader {
position: fixed;
top:0;
left:0;
right:0;
bottom:0;
background-color:#fff; /* change if the mask should have another color then white */
z-index:99; /* makes sure it stays on top */
}
#status {
width:200px;
height:200px;
position:absolute;
left:50%; /* centers the loading animation horizontally one the screen */
top:50%; /* centers the loading animation vertically one the screen */
background-image:url(../img/status.gif); /* path to your loading animation */
background-repeat:no-repeat;
background-position:center;
margin:-100px 0 0 -100px; /* is width and height divided by two */
}
Place following HTML Code directly after the <body> tag.
<!-- Preloader -->
<div id="preloader">
<div id="status"> </div>
</div>
The outer DIV preloader will be called from the CSS file and will cover the entire website with a white DIV.
The inner DIV status will show the loading animation.
If you want to show preloader during AJAX request you can use the following CSS code.
#preloader {
position:fixed;
left: 0px;
top: 0px;
width: 100%;
height: 100%;
background-color:#fff; /* change if the mask should have another color then white */
z-index:99; /* makes sure it stays on top */
}
#status {
width:200px;
height:200px;
position:absolute;
left:50%; /* centers the loading animation horizontally one the screen */
top:50%; /* centers the loading animation vertically one the screen */
background-image:url(../img/status.gif); /* path to your loading animation */
background-repeat:no-repeat;
background-position:center;
margin:-100px 0 0 -100px; /* is width and height divided by two */
}
Your Javascript code will look like:
$("#status").fadeIn();
$("#preloader").fadeIn();
$.get(url, data, function(){
$("#status").fadeOut();
$("#preloader").fadeOut();
});
The image status.gif is will be displayed in the DIV status and is located at /img/status.gif.
