时间格式化 刚刚 N分钟前 N小时前 N天前 N月前 N年前
MM-dd hh:mm 或者 yyyy-MM-dd
前端：
<code><</code><code>span</code> <code>class="time" title="2016-07-23 12:02:32"></</code><code>span</code><code>></code>
用法：
插件： jquery.timeago.js
jquery实现几分钟前、几小时前、几天前等时间差显示效果的代码实例
转：http://www.jb51.net/article/48912.htm
jquery插件实现
HTML代码：
<span class="time timeago" title="<fmt:formatDate value="${comment.createAt}" pattern="yyyy-MM-dd HH:mm:ss"/>"></span>
调用代码：
jQuery("span.timeago").timeago();
插件源码：
(function (factory) {
if (typeof define === 'function' && define.amd) {
// AMD. Register as an anonymous module.
define(['jquery'], factory);
} else {
// Browser globals
factory(jQuery);
}
