JQuery开发之Galleriffic图片插件介绍

Galleriffic是一个用于创建快速展示相册中照片的jQuery插件。从图一中可以看成,图片既可以以幻灯片的方式查看,也可以手动点击缩略图查看。Galleriffic还支持分页,从而使得它能够展示更多的图片。

  Galleriffic的主要特点如下:

  · Smart image preloading after the page is loaded

  · Thumbnail navigation (with pagination)

  · jQuery.history plugin integration to support bookmark-friendly URLs per-image

  · Slideshow (with optional auto-updating url bookmarks)

  · Keyboard navigation

  · Events that allow for adding your own custom transition effects

  · API for controlling the gallery with custom controls

  · Support for image captions

  · Flexible configuration

  · Graceful degradation when javascript is not available

  · Support for multiple galleries per page

  下面,我们结合代码,来阐述Galleriffic的工作原理。

  1. 下载最新版本的Galleriffic与jQuery。jQuery在1.3.2以上。

  2. 在目标HTML代码中引入jQuery库与Galleriffic插件。两者的实现方式均为javascript。

<head>     ...     <script type="text/javascript" src="js/jquery-1.3.2.js"></script>     <script type="text/javascript" src="js/jquery.galleriffic.js"></script>
    
<!-- Optionally include jquery.history.js for history support -->     <script type="text/javascript" src="js/jquery.history.js"></script>     <script type="text/javascript" src="js/jquery.opacityrollover.js"></script>     ... </head>

  3. 添加容器元素Div。值得注意的是,这里所有的Div都是可选的。用户可以根据自己的实际情况做出取舍。

<div id="controls"></div><div id="loading"></div><div id="slideshow"></div><div id="caption"></div><div id="thumbs">     ... 这里用来放图片清单…(见步骤4) </div>

  4. 建立图片清单列表

<div id="thumbs">     <ul class="thumbs noscript">         <li>             <a class="thumb" name="optionalCustomIdentifier" href="path/to/slide" title="your image title">                 <img src="path/to/thumbnail" alt="your image title again for graceful degradation"/>             </a>             <div class="caption">                 (这里用来放标题、描述等信息)             </div>         </li>         ... (接下的就是类似上面的li代码,一个li元素包含一张图片)     </ul></div>

  5. 初始化插件

var gallery = $('#gallery').galleriffic('#thumbs', {        delay:                  3000// 动画播放间隔时间         numThumbs:              20// 所要显示的图片数目         preloadAhead:           40// 设置为-1时预加载所有图片         enableTopPager:         false,         enableBottomPager:      true,         imageContainerSel:      '', // 接下来的三个属性是作为容器的css名        controlsContainerSel:   '', // The CSS selector for the element within which the slideshow controls should be rendered        captionContainerSel:    '', // The CSS selector for the element within which the captions should be rendered        loadingContainerSel:    '', // The CSS selector for the element within which should be shown when an image is loading        renderSSControls:       true, // 是否显示播放与暂停按钮         renderNavControls:      true, // 是否显示前进后退按钮         playLinkText:           'Play',        pauseLinkText:          'Pause',        prevLinkText:           'Previous',        nextLinkText:           'Next',        nextPageLinkText:       'Next &rsaquo;',        prevPageLinkText:       '&lsaquo; Prev',        enableHistory:          false, // Specifies whether the url's hash and the browser's history cache should update when the current slideshow image changes        autoStart:              false, // 是否自动播放         onChange:               undefined, // 接下来是插件的回调函数         onTransitionOut:        undefined, // accepts a delegate like such: function(callback) { ... }         onTransitionIn:         undefined, // accepts a delegate like such: function() { ... }         onPageTransitionOut:    undefined, // accepts a delegate like such: function(callback) { ... }         onPageTransitionIn:     undefined  // accepts a delegate like such: function() { ... }     });
