人类可读的时间javascript/jquery

人类可读的时间javascript/jquery,javascript,jquery,jquery-plugins,Javascript,Jquery,Jquery Plugins,我在John Resig的博客上发现了以下片段: function prettyDate(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

我在John Resig的博客上发现了以下片段:

function prettyDate(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 min" ||
            diff < 3600 && Math.floor( diff / 60 ) + " mins" ||
            diff < 7200 && "1 hour" ||
            diff < 86400 && Math.floor( diff / 3600 ) + " hours") ||
        day_diff == 1 && "Yesterday" ||
        day_diff < 7 && day_diff + " d" ||
        day_diff < 31 && Math.ceil( day_diff / 7 ) + " w";
}

// If jQuery is included in the page, adds a jQuery plugin to handle it as well
if ( typeof jQuery != "undefined" )
    jQuery.fn.prettyDate = function(){
        return this.each(function(){
            var date = prettyDate(this.title);
            if ( date )
                jQuery(this).text( date );
        });
    };

使时间人性化?

只需稍加修改,它就可以工作:

在当前插件中,正在使用
this.title
提取日期字符串,它不会为您的
返回任何内容。在您的情况下,我们可以使用
$this.text()
提取日期字符串

上面的代码段不考虑时区。如果服务器有UTC时区,则需要额外执行
(d.getTimezoneOffset()*60000)
以转换为本地时间

整个功能如下所示:

function prettyDate(time){
    d = new Date();
    var date = new Date((time || "").replace(/-/g,"/").replace(/[TZ]/g," ")),
        diff = ((d.getTime() + (d.getTimezoneOffset()*60000) - 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 min ago" ||
            diff < 3600 && Math.floor( diff / 60 ) + " mins 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 ) + " week ago";
}

// If jQuery is included in the page, adds a jQuery plugin to handle it as well
if ( typeof jQuery != "undefined" )
    jQuery.fn.prettyDate = function(){
        return this.each(function(){
            var $this = jQuery(this),

            if ( date )
                $this.text( date );
        });
    };

$(function() {

    setInterval(function(){ $(".p-date").prettyDate(); }, 5000);
});

时区的事情怎么样,会处理好吗?我想会的,是的。简单代码会将日期与当前日期时间进行区分,因此只要您提供的日期在日期()对象中,就应该正确地解释它。很好,谢谢,如果有任何其他东西不起作用,我可能会让您出错。不客气。如果可以,我会尽力帮助你,但你可能会通过发帖得到更快(更好)的答案;)时区的事情怎么样,会处理好吗?我想会的,是的。简单代码会将日期与当前日期时间进行区分,因此只要您提供的日期在日期()对象中,就应该正确地解释它。很好,谢谢,如果有任何其他东西不起作用,我可能会让您出错。不客气。如果可以,我会尽力帮助你,但你可能会通过发帖得到更快(更好)的答案;)
