对于一些设置北京图片时，常常会不能自动适应屏幕大小，搜索后找到一个方法：
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>
Jquery和CSS使背景图片自动适应大小
</title>
<style type="text/css">
.slideContent { width:100%;filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src='images/da.jpg',
sizingMethod='scale'); -moz-background-size:100% 100%; background-size:100%
100%; }
</style>
<script type="text/javascript" src="js/jquery-1.4.4.min.js">
</script>
<script type="text/javascript">
$(function() {
cover();
$(window).resize(function() {
cover();
});
});
function cover() {
var h = $(window).height();
var w = $(window).width();
$(".slideContent").height(h);
$(".slideContent").width(w);
}
</script>
<body>
<div class="slideContent">
</div>
</body>
</html>
