下面是一个非常不错的 jQuery 插件，与他们在 SO 上使用的插件非常相似。对我来说问题是它用它来转换时间。

<time class="timeago" datetime="2008-07-17T09:24:17Z">July 17, 2008</time>

那会很棒，除非我在我的网站上以 UTC 时间戳而不是格式化时间存储时间，有没有办法将这样的东西转换为使用时间戳？我知道在 PHP 中我可以将我的时间戳转换为这种格式，但是在 PHP 的一页上转换很多次似乎有点过头了。我可能是错的，还有其他人在 jquery 中这样做，但来自真实的时间戳吗？

另外，我目前在一个网站上用 PHP 执行此操作以显示“2 小时 4 分钟前”，但是使用 javascript 而不是 PHP 会更好吗？

最佳答案

我遇到了同样的问题。我使用的是从 PHP 生成的 Unix 时间戳，所以我决定快速破解并扩展 jQuery timeago 的解析功能以另外处理时间戳。奇迹般有效。只需在 jquery.timeago.js 文件中的第 79 行附近查找 Parse 函数，并将其替换为以下内容:

  parse: function(iso8601) {
  if ((iso8601 - 0) == iso8601 && iso8601.length > 0) { // Checks if iso8601 is a unix timestamp
    var s = new Date(iso8601);
    if (isNaN(s.getTime())) { // Checks if iso8601 is formatted in milliseconds
      var s = new Date(iso8601 * 1000); //if not, add milliseconds 
    }
    return s;
  }

  var s = $.trim(iso8601);
  s = s.replace(/-/,"/").replace(/-/,"/");
  s = s.replace(/T/," ").replace(/Z/," UTC");
  s = s.replace(/([\+-]\d\d)\:?(\d\d)/," $1$2"); // -04:00 -> -0400
  return new Date(s);
},
