@H_404_0@本文实例讲述了jquery动态切换背景图片的简单实现方法。分享给大家供大家参考，具体如下：

<div class="jb51code">
<pre class="brush:js;">
(function()
{
var bgCounter = 0,backgrounds = [
"Images/BACKGROUND_1_TEST.png","Images/BACKGROUND_2_TEST.png","Images/BACKGROUND_3_TEST.png"
];
function changeBackground()
{
bgCounter = (bgCounter+1) % backgrounds.length;
$('body').css('background','#000 url('+backgrounds[bgCounter]+') no-repeat');
setTimeout(changeBackground,10000);
}
changeBackground();
})();
