较完整的轮播图特效

js代码：

$(function(){

//主图区域轮播代码

var linum = $('.slider-item').length;

var sitemW = $('.slider-item').width();

var proW = $('.slider-item').width() / linum;//进度条分段宽度值,应是个百分比数

// alert(proW);

var index = 0;

$('.slider-item').mouseover(function(){

index = $('.slider-item').index(this);//这句话可以得到滑过时当前li的索引值，后面没用上

});

var carouselId = window.setInterval(function(){

if(index == linum)

index = 0;

var snum = sitemW * index;//轮播图传参及执行

carouselMoveBy(snum);

var prow = proW*(index+1);//进度条传参及执行

changeProW(prow);

index++;//这句话最关键，跟随着setInterval的index++才能做到定时给索引值，each遍历之类的做不到

},4000);

$('.index-slider').hover(function(){//鼠标滑入时，停止动效

clearInterval(carouselId);

$('.unslider-arrow').addClass('backcolor');//鼠标滑入时，左右箭头的黑色背景逐步显现

 

},function(){//移开光标后，动画继续

$('.unslider-arrow').removeClass('backcolor');//鼠标滑开时，左右箭头的背景色逐步变透明隐藏，即去掉黑色即可
