首先引入jQuery库文件和Easing js文件。

<script type="text/javascript" src="jquery.js"></script> 
<script type="text/javascript" src="jquery.easing.min.js"></script>

jQuery

支持toggle()、slideUp()、slideDown()、show()、hide()等内置的动画效果，使用代码如下：

$(element).show({ 
    duration: 1000,  
    easing: method,  
    complete: callback 
});

参数duration：定义动画时间(毫秒)，时间越短，运动速度越快。

参数easing：定义动画效果，Easing js提供多种动画效果，有匀速运动、变加速运动、缓冲波动效果，多种方法如下：

<ul id="lists"> 
  <li rel="linear">linear</li> 
  <li rel="swing">swing</li> 
  <li rel="jswing">jswing</li> 
  <li rel="easeInQuad">easeInQuad</li> 
  <li rel="easeOutQuad">easeOutQuad</li> 
  <li rel="easeInOutQuad">easeInOutQuad</li> 
  <li rel="easeInCubic">easeInCubic</li> 
  <li rel="easeOutCubic">easeOutCubic</li> 
  <li rel="easeInOutCubic">easeInOutCubic</li> 
  <li rel="easeInQuart">easeInQuart</li> 
  <li rel="easeOutQuart">easeOutQuart</li> 
  <li rel="easeInOutQuart">easeInOutQuart</li> 
  <li rel="easeInQuint">easeInQuint</li> 
  <li rel="easeOutQuint">easeOutQuint</li> 
  <li rel="easeInOutQuint">easeInOutQuint</li> 
  <li rel="easeInSine">easeInSine</li> 
  <li rel="easeOutSine">easeOutSine</li> 
  <li rel="easeInOutSine">easeInOutSine</li> 
  <li rel="easeInExpo">easeInExpo</li> 
  <li rel="easeOutExpo">easeOutExpo</li> 
  <li rel="easeInOutExpo">easeInOutExpo</li> 
  <li rel="easeInCirc">easeInCirc</li> 
  <li rel="easeInOutCirc">easeInOutCirc</li> 
  <li rel="easeInElastic">easeInElastic</li> 
  <li rel="easeOutElastic">easeOutElastic</li> 
  <li rel="easeInOutElastic">easeInOutElastic</li> 
  <li rel="easeInBack">easeInBack</li> 
  <li rel="easeInOutBack">easeInOutBack</li> 
  <li rel="easeInBounce">easeInBounce</li> 
  <li rel="easeOutBounce">easeOutBounce</li> 
  <li rel="easeInOutBounce">easeInOutBounce</li>
</ul>

参数complete：动画结束后回调函数callback。

jQuery Easing也可结合动画函数animate()，代码如下：

$(element).animate({ 
    height:400, 
    width:500 
    },{ 
    easing: 'easeInOutQuad', 
    duration: 800, 
    complete: callback 
});
