将facebook日期格式转换为javascript日期

Question

嗨,我正在使用fql和javascript sdk从facebook获取活动.

如何在javascript日期转换facebook格式的日期？

谢谢

Answer 1

javascript中的日期是1970年1月1日以来的毫秒数字值.自1970年1月1日起,Facebook日期(至少为流表中的creation_time和update_time)以秒为单位,因此您需要乘以1000.这是一些代码,用于执行此操作今天早些时候我墙上的一个帖子(小提琴):

var created_time = 1276808857;
var created_date = new Date(created_time * 1000);
var current_date = new Date();
console.log('Post: ' + moment(created_date).format())
console.log('Now: ' + moment(current_date).format());

结果:

Post: 2010-06-17T16:07:37-05:00
Now: 2013-11-12T16:37:01-06:00

我在这里使用代码来格式化日期:http: //momentjs.com/

为了将图形api"created_time"更改为"之前"日期以匹配facebook,我发现javascript/jquery的有用链接:http://ejohn.org/blog/javascript-pretty-date/

var created_time = "2012-04-10T00:17:46+0000";
alert(timeAgo(created_time));

function timeAgo(time){
var date = new Date((time || "").replace(/-/g,"/").replace(/[TZ]/g," ")),
    diff = (((new Date()).getTime() - date.getTime()) / 1000),
    day_diff = Math.floor(diff / 86400);

if ( isNaN(day_diff) || day_diff < 0 || day_diff >= 31 )
    return;

return day_diff == 0 && (
        diff < 60 && "just now" ||
        diff < 120 && "1 minute ago" ||
        diff < 3600 && Math.floor( diff / 60 ) + " minutes ago" ||
        diff < 7200 && "1 hour ago" ||
        diff < 86400 && Math.floor( diff / 3600 ) + " hours ago") ||
    day_diff == 1 && "Yesterday" ||
    day_diff < 7 && day_diff + " days ago" ||
    day_diff < 31 && Math.ceil( day_diff / 7 ) + " weeks ago";
}
