这是一款jQuery全屏对称分割卡片式轮播图插件。该轮播图插件使用jquery和TweenMax.js来制作。在布局上，将图片和内容分为左右两块区域，轮播图切换时，带有一些视觉差效果。
使用方法
在页面中引入jquery.min.js、TweenMax.min.js文件。
<script src="js/jquery.min.js"></script>
<script src="js/TweenMax.min.js"></script>
HTML结构
轮播图的HTML结构如下。
<div class="slide active">
<div class="card">

<div class="card-content">

初始化插件
在页面DOM元素加载完毕之后，通过下面的方法来初始化该插件。
var $activeSlide = $('.active'),
$homeSlide = $(".slide"),
$slideNavPrev = $("#prev"),
$slideNavNext = $("#next");
function init() {
TweenMax.set($homeSlide.not($activeSlide), {autoAlpha: 0});
TweenMax.set($slideNavPrev, {autoAlpha: 0.2});
}
init();
function goToNextSlide(slideOut, slideIn, slideInAll) {
var t1 = new TimelineLite(),
slideOutContent = slideOut.find('.card-content'),
slideInContent = slideIn.find('.card-content'),
slideOutImg = slideOut.find('.card-img'),
slideInImg = slideIn.find('.card-img'),
index = slideIn.index(),
size = $homeSlide.length;
console.log(index);
if(slideIn.length !== 0) {
t1
.set(slideIn, {autoAlpha: 1, className: '+=active'})
.set(slideOut, {className: '-=active'})
.to(slideOutContent, 0.65, {y: "+=40px", ease: Power3.easeInOut}, 0)
.to(slideOutImg, 0.65, {backgroundPosition :'bottom', ease: Power3.easeInOut}, 0)
.to(slideInAll, 1, {y: "-=100%", ease: Power3.easeInOut}, 0)
.fromTo(slideInContent, 0.65, {y: '-=40px'}, {y : 0, ease: Power3.easeInOut}, "-=0.7")
.fromTo(slideInImg, 0.65, {backgroundPosition: 'top'}, {backgroundPosition: 'bottom', ease: Power3.easeInOut}, '-=0.7')
}
TweenMax.set($slideNavPrev, {autoAlpha: 1});
if(index === size - 1){
TweenMax.to($slideNavNext, 0.3, {autoAlpha: 0.2, ease:Linear.easeNone});
}
};
$slideNavNext.click(function(e) {
e.preventDefault();
var slideOut = $('.slide.active'),
slideIn = $('.slide.active').next('.slide'),
slideInAll = $('.slide');
goToNextSlide(slideOut, slideIn, slideInAll);
});
function goToPrevSlide(slideOut, slideIn, slideInAll) {
var t1 = new TimelineLite(),
slideOutContent = slideOut.find('.card-content'),
slideInContent = slideIn.find('.card-content'),
slideOutImg = slideOut.find('.card-img'),
slideInImg = slideIn.find('.card-img'),
index = slideIn.index(),
size = $homeSlide.length;
if(slideIn.length !== 0) {
t1
.set(slideIn, {autoAlpha: 1, className: '+=active'})
.set(slideOut, {className: '-=active'})
.to(slideOutContent, 0.65, {y: "-=40px", ease: Power3.easeInOut}, 0)
.to(slideOutImg, 0.65, {backgroundPosition :'top', ease: Power3.easeInOut}, 0)
.to(slideInAll, 1, {y: "+=100%", ease: Power3.easeInOut}, 0)
.fromTo(slideInContent, 0.65, {y: '+=40px'}, {y : 0, ease: Power3.easeInOut}, "-=0.7")
.fromTo(slideInImg, 0.65, {backgroundPosition: 'bottom'}, {backgroundPosition: 'top', ease: Power3.easeInOut}, '-=0.7')
}
TweenMax.set($slideNavPrev, {autoAlpha: 1});
if(index === 0){
TweenMax.to($slideNavPrev, 0.3, {autoAlpha: 0.2, ease:Linear.easeNone});
}
};
$slideNavPrev.click(function(e) {
e.preventDefault();
var slideOut = $('.slide.active'),
slideIn = $('.slide.active').prev('.slide'),
slideInAll = $('.slide');
goToPrevSlide(slideOut, slideIn, slideInAll);
});
