jcarousel幻灯片

Question

我正在使用jquery jcarousel作为我的图像滑块，但遇到了问题。问题是每当我点击特定图像滑块图像时都看不到。我的意思是主图像没有变化。欢迎任何帮助。我已经包含了所有需要的jquery和css和脚本。 代码：

<?php
                    if(!empty($detailArr))
                    {
                        foreach($detailArr as $models)
                        {
                        ?>
                        <h1><?php echo $models['model_name'];?></h1>

                       <div class="model_info">
                            <div id="slideshow-main">
                                <ul>
                                    <li class="<?php echo $models['gallery_id'];?> active">
                                        <a href="#">
                                      <img  src="<?php echo base_url();?>images/gallery/large/<?php echo $models['gallery_image'];?>" width="410" height="290" alt="" />
                                        </a>
                                    </li>
                                </ul>
                            </div>


                          <div id="slideshow-carousel">

                                            {
                                                foreach($slideshowArr as $models)
                                                {
                                     ?>
                                    <li>
                                        <a href="<?php echo base_url().$models['model_url']."/".$models['gallery_id'];?>" rel="<?php echo $models['gallery_id'];?>">

首先，您确定已导入jQuery库吗？你可以这样检查：          $（document）.ready（function（）{         警报（1）;     }）;
