近期在网站开发过程中遇到了一个需要组合轮播图片的页面，页面布局如下：
先来讲一下具体功能是：点击左侧“公司资质”或者“产品证书”，右边切换到相应的轮播模块。中间的图片可以左右拖动切换，同时带动右边名称的选中状态切换，右边的名称点击能切换中间的图片，使对应的图片能居中放大显示，也是就是中间的当前图片与右边的名称是一一对应的。
下面再来讲一下页面布局结构如下：
除了以上的html代码外，实现上述的功能还需要下面的js代码，这些代码看起来虽然比较复杂，但使用方法却是比较傻瓜式，直接粘贴到页面上就可以用，所以看不懂以下的JS代码也没关系，但对于一些关键的类名，例如上面的html代码写的hon_con_box1,hon_name_box1,swip_tab2等类名还是要跟JS代码对应起来，不然就实现不了多组合轮播功能，JS代码如下：
if($("body").hasClass("swip_box")){
//资质荣誉
if ($(".imgbox2").hasClass("swip_tab2")){
var sib,sib2,sib3;
if (wind_w > 780){
sib = "vertical";
sib2 = 4;
sib3 = false;
} else {
sib = "horizontal";
sib2 = "auto";
sib3 = true;
}
var serSwiper1 = new Swiper('.hon_con_box1 .swiper-container', {
slideActiveClass: 'active',

spaceBetween: 10,
autoplayDisableOnInteraction : false,
autoplay: {

},

progress: function(progress) {
var i;

for (i = 0; i < this.slides.length; i++) {
var slide = this.slides.eq(i);
var slideProgress = this.slides[i].progress;
modify = 1;
if (Math.abs(slideProgress) > 1) {
modify = (Math.abs(slideProgress) - 1) * 0.3 + 1;
}
translate = slideProgress * modify * sib + 'px';
scale = 1 - Math.abs(slideProgress) / 5;
zIndex = 999 - Math.abs(Math.round(10 * slideProgress));
slide.transform('translateX(' + translate + ') scale(' + scale + ')');
slide.css('zIndex', zIndex);
slide.css('opacity', 1);
if (Math.abs(slideProgress) > 3) {
slide.css('opacity', 0);

if (!activeNav.hasClass('swiper-slide-visible')) {
if (activeNav.index() > serPageSwiper1.activeIndex ) {
var thumbsPerNav = Math.floor(serPageSwiper1.width / activeNav.width()) ;
serPageSwiper1.slideTo(activeNav.index() - thumbsPerNav);
} else {
serPageSwiper1.slideTo(activeNav.index());
}
}
}
var serSwiper2 = new Swiper('.hon_con_box2 .swiper-container', {

serSwiper2.autoplay.stop();
$('.hon_tab_nav_box > div').on('click', function () {
serSwiper1.autoplay.stop();
serSwiper2.autoplay.stop();
$(this).addClass('on').siblings("div").removeClass('on');
var thisIndex = $(this).index();
$(".hon_con_case > div").eq(thisIndex).show().siblings("div").hide();
switch (thisIndex)
{
case 0:
serSwiper1.autoplay.start();
break;
case 1:
serSwiper2.autoplay.start();
break;
}
});
}
}
以上功能是基于 swiper.js 插件最新版本实现的。由于swiper 插件对ie的兼容性不是很到位，所以这里的轮播不兼容ie 低版本，也就是IE8以下的版本均不支持该效果，不过现在用IE8以下的浏览器比较少了，除了window xp系统和少部分的win 7系统外。
