阿里云


iView 是一款效果非常炫酷的支持移动设备的响应式多功能 jQuery 幻灯片插件。该幻灯片插件简单易用,可以嵌入图片和视频,并且它可以制作图片标题的动画效果。可用它来制作幻灯片、banner 轮播图、banner 广告轮播图等等。该插件用 jQuery 代码将 HTML 转换为幻灯片,也可以通过定义 HTML5 data 属性来完成。这些标签都是有效的 HTML5 标签,并且对搜索引擎十分友好,利于 SEO。该幻灯片包含 35 种动画过渡效果,这些效果可以在所有的现代浏览器上工作,包括:ie6 - ie9, Firefox, Chrome, Opera, Safari,以及移动手机平台如 iOS 和 Android。为了减少页面的加载时间,该幻灯片插件基于每一个 slide 进行图片预加载,图片只会在准备显示的时候才被加载。

  1. <link rel="stylesheet" href="iview.css" type="text/css" media="screen" />
  2. <script src="http://gapis.geekzu.org/ajax/ajax/libs/jquery/1/jquery.min.js" type="text/javascript"></script>
  3. <script src="raphael-min.js" type="text/javascript"></script>
  4. <script src="jquery.easing.js" type="text/javascript"></script>
  5. <script src="iview.packed.js" type="text/javascript"></script>

HTML 结构:

该幻灯片插件使用的是嵌套的<div>结构。

  1. <div id="iview">
  2.     <!-- Slide 1 -->
  3.     <div data-iview:thumbnail="photos/photo1_thumb.jpg" data-iview:image="photos/photo1.jpg"></div>
  4.     <!-- Slide 2 -->
  5.     <div data-iview:thumbnail="photos/photo2_thumb.jpg" data-iview:image="photos/photo2.jpg"></div>
  6. </div>

你也可以为每一张图片添加一个标题,你只需要在每个图片<div>中添加一个带 class 为 iview-caption 的<div>元素即可。

  1. <div id="iview">
  2.     <!-- Slide 1 -->
  3.     <div data-iview:thumbnail="photos/photo1_thumb.jpg" data-iview:image="photos/photo1.jpg">
  4.         <!-- Caption -->
  5.         <div class="iview-caption" data-x="0" data-y="0" data-width="400" data-height="300" data-transition="wipeRight" data-speed="700"><h3>The Responsive Caption</h3>This is the product that you <b><i>all have been waiting for</b></i>!<br><br>Customize this slider with just a little HTML and CSS to your very needs. Give each slider some captions to transport your message.<br><br>All in all it works on every browser (including IE6 / 7 / 8) and on iOS and Android devices!</div>
  6.     </div>
  7.     <!-- Slide 2 -->
  8.     <div data-iview:thumbnail="photos/photo2_thumb.jpg" data-iview:image="photos/photo2.jpg">
  9.         <!-- Caption -->
  10.         <div class="iview-caption" data-x="70" data-y="70" data-transition="expandLeft">Caption Description</div>
  11.     </div>
  12. </div>

如果你添加了多个图片标题到 iview-caption DIV 中,你可以决定每一个图片标题的动画效果。可用的动画效果有:"wipeLeft", "wipeRight", "wipeTop", "wipeBottom", expandLeft , expandRight , expandTop , expandBottom , fade 。

  1. <div class="iview-caption" data-transition="fade">Caption description</div>

下面是更多的可用的 HTML5 data-attributes 属性。

HTML5 data 属性:

该幻灯片插件的图片 URL 使用的是 HTML5 data-属性,这将允许我们只在准备显示图片的时候才加载图片(懒加载)。通过 HTML5 data- 属性你还可以添加其它的属性到幻灯片上。例如添加缩略图的 URL:

  1. <div data-iview:thumbnail="photos/photo1_thumb.jpg" data-iview:image="photos/photo1.jpg"></div>

或者为幻灯片添加过渡动画效果:

  1. <div data-iview:image="photos/photo1.jpg" data-iview:transition="zigzag-top"></div>

你也可以设置一个随机的动画过渡效果:

  1. <div data-iview:image="photos/photo1.jpg" data-iview:transition="zigzag-top,top-curtain,fade"></div>
