jquery.easing.js是个好东西，各种动画效果扩展，加强和丰富了jquery自带的各种动画函数
box点击就会像移动出弹簧效果，$(obj).animate(目的状态，时间，回调函数)
<!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title></title> <style> body { position:relative; width:100%; height:100px; } #box { position:absolute; width:100px; height:100px; background-color:red; top:0px; left:0px; cursor:pointer; } </style> </head> <body> <div class="box" id="box"></div> <script type="text/javascript" src="/js/jquery-1.8.3.min.js"></script> <script type="text/javascript" src="/js/jquery.easing.js"></script> <script type="text/javascript"> $(document).ready(function () { $("#box").click(function () { $(this).stop(true, true).animate({ left:‘400px‘ }, 2000, ‘easeInOutElastic‘, function () { $(this).animate({ left: ‘0px‘ }, 2000, ‘easeInOutElastic‘); }); }); }); </script> </body> </html>
还支持toggle()、slideUp()、slideDown()、show()、hide()等jQuery内置的动画效果函数
