javascript 45种缓动效果 非常酷

ble class="3waterborder" style="FONT-SIZE: 12px" cellspacing="0" cellpadding="0" border="1"> 参数 类型 说明 el element 必需，为页面元素 begin number 必需，开始的位置 change number 必需，要移动的距离 duration number 可选，缓动效果持续时间，默认是500ms。建议取300~1000ms。 field string 必需，要发生变化的样式属性。请在top，left，bottom,right，width与height中选择。 ftp number 可选，每秒进行多少帧动画，默认50帧，保证流畅播放。一些参考资料，日本动画1秒36帧，中国卡通24帧，赛车游戏60帧。 ease function 必需，缓动公式，参数为0~1之间的数。可参考我下面给出的45条公式。 onStart function 可选，在开始时执行。 onEnd function 可选，在结束时执行。 prototype流派的缓动公式，只需一个参数（增至45种）
