实现复杂的jQuery图像滑块时卡住了

我在修改 THIS 滑块时遇到了一些问题。

这里缩略图&主显示图像具有一对一的关系,即通过点击1个缩略图,它显示单个图像&然后它滑到下一个缩略图&显示其相关图像&等等。

现在,我想以这样一种方式修改这个滑块:一个缩略图应该与多个图像相关/链接,即一个缩略图与多个主显示图像的关系(一对多)

即点击“卧室缩略图”(如附图 SCREENSHOT所示),它应该只显示&幻灯片5(或n)与此特定缩略图相关的图像数量,然后以相同的方式点击“浴室缩略图”,它应显示&幻灯片5(或n)与此特定部分相关的图像数量&等等。所以这就是我想要将代码从一对一修改为[一个缩略图到一个主显示图像]到一对多[一个缩略图到5或n个与该特定缩略图相关的图像]

My Modified Thumbnail Section的HTML代码相同。

我修改了主图像部分,如图所示..

<div id="lofslidecontent45" class="lof-slidecontent" style="width:670px;height:236px;">
<div class="preload"><div></div></div>
<div class="lof-main-outer" style="width:670px; height:236px;">
<ul class="lof-main-wapper">
    <li>
        <ul class=”lof-main-subwapper”>
                    <li>
 <img src="images/slider1.jpg" title="Newsflash 2" >           
                        <div class="lof-main-item-desc">
                        <h3>Innovation</h3>
<h2>lorem ipsum is simply dummy text</h2>
                        </div>
                    </li>
                     <li>
                         ..
                     </li>
         </ul>
     </li>
     <li>
        <ul class=”lof-main-subwapper”>
            <li>
                …
            </li>
            <li>
                …
            </li>
        </ul>
    </li>
</ul>
</div>
</div>

我正在修改滑块的脚本代码,到目前为止,我已经添加了另一个wrappersub类&amp;在将图像组链接到一个缩略图时,我被卡住了,即将主图像部分的ul与缩略图的链接相关联...

任何帮助都将不胜感激。

也许您可以尝试在另一个滑块内添加幻灯片,以支持更多内容,例如Anything Slider。我已经在项目中使用它,并且在幻灯片中添加我自己的自定义内容时运气不错。

尝试将“var”添加到第238行,它变为:var seft = this;
