jQuery淡入淡出

我弄乱了html，css和jquery，并且遇到了这个问题。我有一个幻灯片显示，该幻灯片使用容器中的fadeIn和fadeOut获取图像，但是当我按“ next”时，它将重置页面并将下一张图像加载到底部的某个位置。你能告诉我什么问题吗？

的HTML

<div class="slideshow ">
<div class="container">
<div class="slides">
<img class ="slide active-slide" src="http://gearnuke.com/wp-content/uploads/2015/06/GTA-5.jpg">
<img class ="slide" src="http://cdn.wegotthiscovered.com/wp-content/uploads/gta5.jpg">
<img class ="slide" src="http://www.igta5.com/images/official-artwork-trevor-yellow-jack-inn.jpg">
<img  class="slide" src="http://cdn2.knowyourmobile.com/sites/knowyourmobilecom/files/styles/gallery_wide/public/0/67/GTAV-GTA5-Michael-Sweatshop-1280-2277432.jpg?itok=nKEHENTW">
</div>
</div>



<div class="container ">
<ul class="slider-dots">
<a href="#/" class="arrow-prev"><<</a>
    <li class="dot active-dot">&bull;</li>
    <li class="dot">&bull;</li>
    <li class="dot">&bull;</li>
    <li class="dot">&bull;</li>
<a href="#/" class="arrow-next">>></a>
</ul>
</div>
</div>

jQuery的

var main=function(){
$('.arrow-next').click(function(event){
    event.stopPropagation();
    var currentSlide=$('.active-slide');
    var nextSlide=$('.active-slide').next();

    var currentDot=$('.active-dot');
    var nextDot=currentDot.next();

    if(nextSlide.length==0) {nextDot=$('.dot').first(); nextSlide=$('.slide').first();}

    currentSlide.fadeOut().removeClass('active-slide');
    nextSlide.fadeIn().addClass('active-slide');

    currentDot.removeClass('active-dot');
    nextDot.addClass('active-dot');


}); 

$('.arrow-prev').click(function(event){
    event.stopPropagation();
    var currentSlide=$('.active-slide');
    var prevSlide=currentSlide.prev();

    var currentDot=$('.active-dot');
    var prevDot=currentDot.prev();

if(prevSlide.length==0) {prevDot=$('.dot').last(); prevSlide=$('.slide').last();}

    currentSlide.fadeOut().removeClass('active-slide');
    prevSlide.fadeIn().addClass('active-slide');

    currentDot.removeClass('active-dot');
    prevDot.addClass('active-dot');

}); 

};

$（document）.ready（main）;
