jQuery javascript框架

jQuery是一个兼容多浏览器的javascript框架，核心理念是write less,do more(写得更少,做得更多)。jQuery在2006年1月由美国人John Resig在纽约的barcamp发布，吸引了来自世界各地的众多JavaScript高手加入，由Dave Methvin率领团队进行开发。

基于jquery的动画效果代码，挺有意思的，需要的朋友可以参考下
jquery动画
有意思的地方见效果图：

思想：
将图片设置分割div的背景图片，控制div的属性，可以现实有趣的滤镜效果，本例中展示了一种，感兴趣的朋友可以尝试其他滤镜的实现。
本例其余动画部分，主要是利用jquery中提供animate和delay实现。
animate：这个函数的关键在于指定动画形式及结果样式属性对象。这个对象中每个属性都表示一个可以变化的样式属性。
delay：设置一个延时来推迟执行队列中之后的项目。
实例效果：
