创意堆叠卡片切换动画特效

这是一组非常有创意的堆叠卡片切换动画特效。这些堆叠卡片切换效果通过点击“确定”或“取消”按钮，以不同的方式将最上面的卡片切换到底部。这14最后卡片切换动画创意十足，效果非常炫酷。

炫酷堆叠卡片切换动画特效使用方法

HTML结构

在第一种效果中，它的HTML结构如下：< ul >元素中的图片将被制作为一个堆栈结构，所有图片以绝对定位的方式互相堆叠在一起。div.controls是两个控制按钮。当点击“Accept”或“Reject”按钮的时候，当前图片堆栈顶部的图片会被添加accept或reject class。

<ul id="stack_yuda" class="stack stack--yuda">
  <li class="stack__item"><img src="img/1.png" alt="Tree 1" /></li>
  <li class="stack__item"><img src="img/2.png" alt="Tree 2" /></li>
  <li class="stack__item"><img src="img/3.png" alt="Tree 3" /></li>
  <li class="stack__item"><img src="img/4.png" alt="Tree 4" /></li>
  <li class="stack__item"><img src="img/5.png" alt="Tree 5" /></li>
  <li class="stack__item"><img src="img/6.png" alt="Tree 6" /></li>
</ul>
<div class="controls">
  <button class="button button--sonar button--reject" data-stack="stack_yuda">
    <i class="fa fa-times"></i>
    <span class="text-hidden">Reject</span>
  </button>
  <button class="button button--sonar button--accept" data-stack="stack_yuda">
    <i class="fa fa-check"></i>
    <span class="text-hidden">Accept</span>
  </button>
</div>

JavaScript

对于这个例子中，main.js文件中提供了一些函数来实现各种功能。动画的实现使用的是dynamics.js动画库。而移动卡片的动画则是通过CSS3动画来实现的。

插件有一些的一些参数选项：

Stack.prototype.options = {
  // stack的透视值
  perspective: 1000,
 
  // stack的透视原点
  perspectiveOrigin : '50% -50%',
 
  // stack的可见项目数量
  visible : 3,
 
  // 无限循环
  infinite : true,
 
  // callback: 当到达栈顶时触发
  onEndStack : function() {return false;},
 
  // animation settings for the items' movements in the stack when the items rearrange
  // object that is passed to the dynamicsjs animate function (see more at #/)
  // example:
  // {type: dynamics.spring,duration: 1641,frequency: 557,friction: 459,anticipationSize: 206,anticipationStrength: 392}
  stackItemsAnimation : {
    duration : 500,
    type : dynamics.bezier,
    points : [{'x':0,'y':0,'cp':[{'x':0.25,'y':0.1}]},{'x':1,'y':1,'cp':[{'x':0.25,'y':1}]}]
  },
 
  // delay for the items' rearrangement / delay before stackItemsAnimation is applied
  stackItemsAnimationDelay : 0,
 
  // animation settings for the items' movements in the stack before the rearrangement
  // we can set up different settings depending on whether we are approving or rejecting an item
  stackItemsPreAnimation : {
    reject : {
      // if true, then the settings.properties parameter will be distributed through the items in a non equal fashion
      // for instance, if we set settings.properties = {translateX:100} and we have options.visible = 4, 
      // then the second item in the stack will translate 100px, the second one 75px and the third 50px
      elastic : true,
      // object that is passed into the dynamicsjs animate function - second parameter -  (see more at #/)
      animationProperties : {},
      // object that is passed into the dynamicsjs animate function - third parameter - (see more at #/)
      animationSettings : {} 
    },
    accept : {
      // if true, then the settings.properties parameter will be distributed through the items in a non equal fashion
      // for instance, if we set settings.properties = {translateX:100} and we have options.visible = 4, 
      // then the second item on the stack will translate 100px, the second one 75px and the third 50px
      elastic : true,
      // object that is passed into the dynamicsjs animate function - second parameter -  (see more at #/)
      animationProperties : {},
      // object that is passed into the dynamicsjs animate function (see more at #/)
      animationSettings : {}
    }
  }
}      

对于这个例子中使用的CSS3动画代码如下：

/******************** yuda *********************/
.stack--yuda .stack__item--reject {
  -webkit-animation: yudaReject 0.5s forwards;
  animation: yudaReject 0.5s forwards;
}
 
@-webkit-keyframes yudaReject {
  to {
    opacity: 0;
    -webkit-transform: translate3d(0, 200px, 0);
    transform: translate3d(0, 200px, 0);
  }
}
 
@keyframes yudaReject {
  to {
    opacity: 0;
    -webkit-transform: translate3d(0, 200px, 0);
    transform: translate3d(0, 200px, 0);
  }
}
 
.stack--yuda .stack__item--accept {
  -webkit-transform-origin: 50% 300%;
  transform-origin: 50% 300%;
  -webkit-animation: yudaAccept 0.5s forwards;
  animation: yudaAccept 0.5s forwards;
}
 
@-webkit-keyframes yudaAccept {
  to {
    opacity: 0;
    -webkit-transform: rotate3d(0, 0, 1, 20deg);
    transform: rotate3d(0, 0, 1, 20deg);
  }
}
 
@keyframes yudaAccept {
  to {
    opacity: 0;
    -webkit-transform: rotate3d(0, 0, 1, 20deg);
    transform: rotate3d(0, 0, 1, 20deg);
  }
}
