- properties:一组包含作为动画属性和终值的样式属性和及其值的集合
- duration(可选):动画执行时间,其值可以是三种预定速度之一的字符串("slow", "normal", or "fast")或表示动画时长的毫秒数值(如:1000)
- easing(可选):要使用的过渡效果的名称,如:"linear" 或"swing"
- complete(可选):在动画完成时执行的函数
其中参数easing默认有两个效果:"linear"和"swing",如果需要更多效果就要插件支持了, 提供了像"easeOutExpo"、"easeOutBounce"等30多种效果,大家可以 去看每一种easing的演示效果,下面详细介绍下其使用方法及每种easing的曲线图。
引入之后,easing参数可选的值就有以下32种:
- linear
- swing
- easeInQuad
- easeOutQuad
- easeInOutQuad
- easeInCubic
- easeOutCubic
- easeInOutCubic
- easeInQuart
- easeOutQuart
- easeInOutQuart
- easeInQuint
- easeOutQuint
- easeInOutQuint
- easeInExpo
- easeOutExpo
- easeInOutExpo
- easeInSine
- easeOutSine
- easeInOutSine
- easeInCirc
- easeOutCirc
- easeInOutCirc
- easeInElastic
- easeOutElastic
- easeInOutElastic
- easeInBack
- easeOutBack
- easeInOutBack
- easeInBounce
- easeOutBounce
- easeInOutBounce
jQuery 1.4版本中对animate()方法,easing的方法进行了扩展,支持为每个属性指定easing方法,详细请参考,如:
$(myElement).animate({ left: [500, 'swing'], top: [200, 'easeOutBounce'] });
也可以用另外一种写法:
$(myElement).animate({ left: 500, top: 200 }, { specialEasing: { left: 'swing', top: 'easeOutBounce' } });
使用jQuery内置动画函数如slideUp()、slideDown()等来指定easing效果,以下两种方法都可以:
$(myElement).slideUp(1000, method, callback}); $(myElement).slideUp({ duration: 1000, easing: method, complete: callback });
