Javascript 网格 slider

Question

我正在尝试创建一个 2x2 网格 slider /产品 slider 。每张幻灯片在 2x2 网格中有 4 张图像。我正在努力思考我将如何做这件事。我目前有一个列表结构

<div class="slider">
    <ul>
      <li></li>
        <ul>
          <li class="slider-product">product 1a</li>
          <li class="slider-product">product 2a</li>
          <li class="slider-product">product 3a</li>
          <li class="slider-product">product 4a</li>
        </ul>
      <li></li>
        <ul>
          <li class="slider-product">product 1b</li>
          <li class="slider-product">product 2b</li>
          <li class="slider-product">product 3b</li>
          <li class="slider-product">product 4b</li>
        </ul>
    </ul>
  </div>

但我不确定如何继续。谁能给我举个例子？

如果我正确理解你想要什么，它看起来像这样:

HTML:

<table>
    <tr>
        <td class="slider slider-0">
           <div class="navigation">
               <img src="http://upload.wikimedia.org/wikipedia/commons/5/51/Mandarin.duck.arp.jpg" class="img" />
               <span class="nav nav-left"><<</span>
               <span class="nav nav-right">>></span>
           </div>
        </td>
        <td class="slider slider-1">
           <div class="navigation">
               <img src="http://critterbabies.com/wp-content/gallery/kittens/happy-kitten-kittens-5890512-1600-1200.jpg" class="img" />
               <span class="nav nav-left"><<</span>
               <span class="nav nav-right">>></span>
           </div>
        </td>
    </tr>
    <tr>
       <td class="slider slider-2">
               <img src="http://www.thehamtramckreview.com/wp-content/uploads/2014/07/backyard-chickens.jpg" class="img" />
           <div class="navigation">
               <span class="nav nav-left"><<</span>
               <span class="nav nav-right">>></span>
           </div>
       </td>
       <td class="slider slider-3">
           <div class="navigation">
               <img src="http://www.hedweb.com/animimag/parrot.jpg" class="img" />
               <span class="nav nav-left"><<</span>
               <span class="nav nav-right">>></span>
           </div>
       </td> 
    </tr>

CSS:

.slider, .img {
    width:200px;
    height:200px;
    background-color:blue;
}

.nav {
    position: relative;
    background-color:green;
}

.nav:hover {
    font-size:18px;
}

.nav:active {
    font-size:16px;
}

.nav-right {
    left:80%;
}

.hidden {
    display:none;
}

Javascript:

$(function() {
    var curSlide = [0, 0, 0, 0];

    $('.nav').click(function() {
        var rowIndex = $(this).closest('tr').index(),
            addToI   = (rowIndex != 0) ? rowIndex + 1 : 0,
            i        = $(this).closest('td').index() + addToI,
            slider   = $('.slider-' + i),
            products = $('.products-' + i),
            left     = $(this).hasClass('nav-left');

        if (left) {
            curSlide[i] = (curSlide[i] > 0) ? curSlide[i] - 1 : products.children('li').length - 1;
        } else {
            curSlide[i] = (curSlide[i] < products.children('li').length - 1) ? curSlide[i] + 1 : 0;
        }

        var src = products.find('li:eq(' + curSlide[i] + ')').text();
        slider.find('img').attr('src', src);
    });
});

这是一个 fiddle
