jQuery时间从时间戳记开始吗? [英] jQuery Time ago from a timestamp?
问题描述
下面是一个非常不错的jQuery插件，非常类似于他们在SO上使用的插件.对我来说，问题是它使用它来转换时间.
Below is a really nice time ago plugin for jQuery, very similar to what they use here on SO. The problem for me is that it uses this to convert time.
<time class="timeago" datetime="2008-07-17T09:24:17Z">July 17, 2008</time>
那太好了，除了我将时间以UTC时间戳而不是格式化的时间存储在我的网站上，有没有办法转换这样的东西以使用时间戳?我知道在PHP中我可以将时间戳转换为这种格式，但是在PHP的1页上转换很多时间似乎有点过头了.我可能是错的，其他人都在jquery中执行此操作，但是是从实时时间戳开始的?
That would be great except that I store time on my site in UTC timestamp and not as a formatted time, is there a way to convert something like this to use a timestamp? I know in PHP I could convert my timestamp to this format but it seems like overkill with converting a LOT of times on 1 page in PHP. I could be wrong, anyone else do this in jquery but from real timestamp?
我目前还在网站上的PHP中显示"2小时4分钟前"，但是wou7ld最好使用javascript而不是PHP?
Also I currently do this in PHP on a site to show "2 hours 4 minutes ago" but wou7ld it be better to use javascript for this instead of PHP?

推荐答案
我遇到了同样的问题.我使用的是从PHP生成的Unix时间戳，因此我决定进行快速修改，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文件的第79行附近查找Parse函数，然后替换为以下内容:
I had the same problem. I'm using Unix timestamps which are generated from PHP, so I decided to do a quick hack and extend the parsing function of jQuery timeago to handle timestamps additionally. Works like a charm. Simply look for the Parse function at around line 79 in the jquery.timeago.js file, and replace with the following:
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);
},
