瀑布流布局与 jQuery Ajax 分页

阅读更多关于瀑布流布局与 jQuery Ajax 分页

在 Kayo 的上一篇文章轻图床的新前端与瀑布流布局曾经简略介绍过瀑布流布局，所谓的瀑布流效果就正如轻图床首页效果那样，多个内容相近的栏目紧密排列，尽量使到栏目间的间隙最小（即流体布局），并且随着页面滚动条向下滚动，新的数据会追加至当前页面的尾部直到所有数据加载完毕（滚动触发的 Ajax 翻页）。本文将会介绍如何实现瀑布流布局中的 Ajax 翻页，至于如何实现栏目间的紧密排列，本文将会简略介绍但不在重要的讨论范围。一.实现原理实现瀑布流布局主要分为两个部分，一是实现流体布局，这里我们采用绝对定位的方式实现，而是滚动触发的 Ajax 分页，这里采用 jQuery 的 Ajax 实现。第一部分将会采用 Masonry jQuery plugin 。Masonry jQuery plugin 是一款实现流体布局的 jQuery 插件，下文将以轻图床的首页 HTML 为例，给出一个 Masonry 流体布局的实例。第二部分使用 jQuery 的 scroll() 事件触发 Ajax ，触发后使用 jQuery 的 ajax() 方法异步加载新内容，下文将给出完整实例。二.Masonry 实现的流体布局假设网站中的 HTML 如下 <div id="content">  <div id="thumbs">
