jquery相册源码

鼠标移到控制点显示缩略图的jquery相册源码,兼容IE6。里面用到了一些css3效果,可能在IE8以下浏览器显示效果不如火狐等好看。建议升级您的IE浏览器或者换成别的内核的浏览器以达到更好的体验效果。

使用方法

1、在头部引入如下代码:

<link rel="stylesheet" type="text/css" href="css/style.css" />
<script type="text/javascript" src="http://www.5imoban.net/download/jquery/jquery-1.8.3.min.js"></script>


2、把以下代码拷贝到你想引用的地方

<div id="ps_container" class="ps_container">
    <div class="ps_image_wrapper">
     <!-- First initial image -->
     <img src="images/1.jpg" alt="" />
    </div>
    <!-- Navigation items -->
    <div class="ps_next"></div>
    <div class="ps_prev"></div>
    <!-- Dot list with thumbnail preview -->
    <ul class="ps_nav">
     <li class="selected"><a href="images/1.jpg" rel="images/thumbs/1.jpg">Image 1</a></li>
     <li><a href="images/2.jpg" rel="images/thumbs/2.jpg">Image 2</a></li>
     <li><a href="images/3.jpg" rel="images/thumbs/3.jpg">Image 3</a></li>
     <li><a href="images/4.jpg" rel="images/thumbs/4.jpg">Image 4</a></li>
     <li><a href="images/5.jpg" rel="images/thumbs/5.jpg">Image 5</a></li>
     <li><a href="images/6.jpg" rel="images/thumbs/6.jpg">Image 6</a></li>
     <li><a href="images/7.jpg" rel="images/thumbs/7.jpg">Image 7</a></li>
     <li><a href="images/8.jpg" rel="images/thumbs/8.jpg">Image 8</a></li>
     <li><a href="images/9.jpg" rel="images/thumbs/9.jpg">Image 9</a></li>
     <li><a href="images/10.jpg" rel="images/thumbs/10.jpg">Image 10</a></li>
     <li class="ps_preview">
      <div class="ps_preview_wrapper">
       <!-- Thumbnail comes here -->
      </div>
      <!-- Little triangle -->
      <span></span>
     </li>
    </ul>
   </div>
   
  </div>
  <!-- The JavaScript -->
        <script type="text/javascript">
