jQuery animate easing使用方法

Jun 20, 2016 am 08:42 AM

从jQuery API 文档中可以知道,jQuery自定义动画的函数.animate( properties [, duration] [, easing] [, complete] )有四个参数:

 

  • 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,jQuery Easing Plugin提供了像"easeOutExpo"、"easeOutBounce"等30多种效果,大家可以点击这里去看每一种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。

jQuery easing 使用方法

首先,项目中如果需要使用特殊的动画效果,则需要在引入jQuery之后引入jquery.easing.1.3.js
<span style="color: #0000ff;"><span style="color: #800000;">script </span><span style="color: #ff0000;">type</span><span style="color: #0000ff;">="text/javascript"</span><span style="color: #ff0000;"> src</span><span style="color: #0000ff;">="http://code.jquery.com/jquery-1.8.3.js"</span><span style="color: #0000ff;">></span><span style="color: #800000;">script</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"><span style="color: #800000;">script </span><span style="color: #ff0000;">type</span><span style="color: #0000ff;">="text/javascript"</span><span style="color: #ff0000;"> src</span><span style="color: #0000ff;">="http://gsgd.co.uk/sandbox/jquery/easing/jquery.easing.1.3.js"</span><span style="color: #0000ff;">></span><span style="color: #800000;">script</span><span style="color: #0000ff;">></span> </span></span>

引入之后,easing参数可选的值就有以下32种:

 

  1. linear
  2. swing
  3. easeInQuad
  4. easeOutQuad
  5. easeInOutQuad
  6. easeInCubic
  7. easeOutCubic
  8. easeInOutCubic
  9. easeInQuart
  10. easeOutQuart
  11. easeInOutQuart
  12. easeInQuint
  13. easeOutQuint
  14. easeInOutQuint
  15. easeInExpo
  16. easeOutExpo
  17. easeInOutExpo
  18. easeInSine
  19. easeOutSine
  20. easeInOutSine
  21. easeInCirc
  22. easeOutCirc
  23. easeInOutCirc
  24. easeInElastic
  25. easeOutElastic
  26. easeInOutElastic
  27. easeInBack
  28. easeOutBack
  29. easeInOutBack
  30. easeInBounce
  31. easeOutBounce
  32. easeInOutBounce
当 然一般一个项目中不可能会用到这么多效果,为了减少代码冗余,必要时可以不用引入整个jquery.easing.1.3.js,我们可以只把我们需要的 几种easing放入Javascript文件中,如项目中只用到"easeOutExpo"和"easeOutBounce"两种效果,只需要下面的代 码就可以了
<span style="color: #000000;"> jQuery.extend( jQuery.easing,  
{  
    easeOutExpo: </span><span style="color: #0000ff;">function</span><span style="color: #000000;"> (x, t, b, c, d) {  
        </span><span style="color: #0000ff;">return</span> (t==d) ? b+c : c * (-Math.pow(2, -10 * t/d) + 1) + b;  
<span style="color: #000000;">    },  
    easeOutBounce: </span><span style="color: #0000ff;">function</span><span style="color: #000000;"> (x, t, b, c, d) {  
        </span><span style="color: #0000ff;">if</span> ((t/=d) )) {  
            <span style="color: #0000ff;">return</span> c*(7.5625*t*t) +<span style="color: #000000;"> b;  
        } </span><span style="color: #0000ff;">else</span> <span style="color: #0000ff;">if</span> (t return c*(7.5625*(t-=(1.5/2.75))*t + .75) + b;  
        } <span style="color: #0000ff;">else</span> <span style="color: #0000ff;">if</span> (t return c*(7.5625*(t-=(2.25/2.75))*t + .9375) + b;  
        } <span style="color: #0000ff;">else</span><span style="color: #000000;"> {  
            </span><span style="color: #0000ff;">return</span> c*(7.5625*(t-=(2.625/2.75))*t + .984375) + b;  
<span style="color: #000000;">        }  
    },  
});  </span>

使用jQuery自定义动画函数animate来指定easing效果,如自定义一种类弹簧效果的动画:

 

<span style="color: #000000;"> $(myElement).animate({  
    top: </span>500<span style="color: #000000;">,  
    opacity: </span>1<span style="color: #000000;">  
}, </span>1000, 'easeOutBounce');
Copy after login

 

值得一提的是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,详细请参考这里,如:

<span style="color: #008000;">//</span><span style="color: #008000;">第一种写法</span>
<span style="color: #000000;"> $(myElement).animate({  
    left: [</span>500, 'swing'<span style="color: #000000;">],  
    top: [</span>200, 'easeOutBounce'<span style="color: #000000;">]  
});  
</span><span style="color: #008000;">//</span><span style="color: #008000;">第二种写法</span>
<span style="color: #000000;"> $(myElement).animate({  
    left: </span>500<span style="color: #000000;">,  
    top: </span>200<span style="color: #000000;">  
}, {  
    specialEasing: {  
        left: </span>'swing'<span style="color: #000000;">,  
        top: </span>'easeOutBounce'<span style="color: #000000;">  
    }  
});  </span>
Copy after login

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<span style="color: #000000;">, method, callback});  
$(myElement).slideUp({  
    duration: </span>1000<span style="color: #000000;">,   
    easing: method,   
    complete: callback  
});  </span>
Copy after login
