onLeave	滚动前的回调函数，接收 index、nextIndex 和 direction 3个参数：index 是离开的“页面”的序号，从1开始计算；nextIndex 是滚动到的“页面”的序号，从1开始计算；direction 判断往上滚动还是往下滚动，值是 up 或 down。
afterRender	页面结构生成后的回调函数，或者说页面初始化完成后的回调函数
afterSlideLoad	滚动到某一水平滑块后的回调函数，与 afterLoad 类似，接收 anchorLink、index、slideIndex、direction 4个参数
onSlideLeave	某一水平滑块滚动前的回调函数，与 onLeave 类似，接收 anchorLink、index、slideIndex、direction 4个参数

jQuery Easing.js 插件

介绍：easing是jquery的一个插件，使用它可以创建更加绚丽的动画效果。

环境：因为easing是jQuery的插件，所以必须是在引入jquery之后再引入它

如果只想要简单的写法就用

$(".car").animate({"left": "150%"},  4000, "easeInElastic", function() {});

easing:格式为json,{duration:持续时间,easing:过渡效果,complete:成功后的回调函数}

$(element).animate({ 
    height:500, 
    width:600 
    },{ 
    easing: 'easeInOutQuad', 
    duration: 500, 
    complete: function(){} 
});

动画复习

视差滚动插件

视差滚动（Parallax Scrolling）指网页滚动过程中，多层次的元素进行不同程度的移动，视觉上形成立体运动效果的网页展示技术

主要核心就是前景和背景以不同的速度移动，从而创造出3D效果。这种效果可以给网站一个很好的补充。

特性

视差滚动效果酷炫，适合于个性展示的场合。

视差滚动徐徐展开，适合于娓娓道来，讲故事的场合。

视差滚动容易迷航，需要具备较强的导航功能。

原理

传统的网页的文字、图片、背景都是一起按照相同方向相同速度滚动的，而视差滚动则是在滚动的时候，内容和多层次的背景实现或不同速度，或不同方向的运动。

有的时候也可以加上一些透明度、大小的动画来优化显示。

利用background-attachment属性实现。

background-attachment: fixed || scroll || local

Stellar.js是什么？

stellar.js 是一个 jQuery插件，能很容易地给网站添加视差滚动效果。尽管已经停止了维护，但它非常稳定，与最新版本的jQuery兼容，很多开发者也在使用它。这个插件在jQuery插件库里很流行。

js调用函数

$.stellar({
    horizontalScrolling: false,
    responsive: true
});

详细参数

名称	说明
horizontalScrolling 和 verticalScrolling	该配置项用来设置视差效果的方向。horizontalScrolling设置水平方向，verticalScro设置垂直方向，为布尔值，默认为true
responsive	该配置项用来制定load或者resize时间触发时是否刷新页面，其值为布尔值，默认为false
hideDistantElements	该配置项用来设置移出视线的元素是否隐藏，其值为布尔值，若不想隐藏则设置为false`
data-stellar-ratio="2"	定义了此元素针对页面滚动的速度比率，比如，0.5为页面滚动的50%，2为页面滚动的200%，所以数值越大，你可以看到页面元素滚动速度越快。
data-stellar-background-ratio	该配置项用在单个元素中，其值为一个正数，用来改变被设置元素的影响速度。例如值为0.3时，则表示背景的滚动速度为正常滚动速度的0.3倍。如果值为小数时最好在样式表中设置
