本文实例讲述了jquery显示loading图片直到网页加载完成的方法。分享给大家供大家参考。具体实现方法如下：
<!DOCTYPE html>
<html class="no-js">
<head>
<meta charset='UTF-8'>
<title>Simple Loader</title>
<style>
/* This only works with JavaScript,
if it's not present, don't show loader */
.no-js #loader { display: none; }
.js #loader { display: block; position: absolute; left: 100px; top: 0; }
</style>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<script src="https://github.com/Modernizr/Modernizr/raw/master/modernizr.js"></script>
<script>
// Wait for window load
$(window).load(function() {
// Animate loader off screen
$("#loader").animate({
top: -200
}, 1500);
});
</script>
</head>
<body>
<img src="download.png" id="loader">
<img src="http://farm6.static.flickr.com/5299/5400751421_55d49b2786_o.jpg">
</body>
</html>
