Javascript 修改prettyDate（）以使用另一种日期时间格式的字符串

我正在使用John Resig prettyDate函数，以便将其与以下格式的字符串一起使用：

'2013-01-04 20:02:28'

但到目前为止我还没有成功…此函数仅适用于iso日期时间

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 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";
}

请问，有人能帮我修改一下以适应我的格式吗？谢谢

PD:

不是格式不起作用，而是函数

在
day\u diff>=31时返回
s。从现在起，当函数运行时，
day_diff
将为47

从条件中删除复选框，并将一个条件添加到返回部分，该返回部分处理
日差
大于31时的情况：

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 )
        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" ||
        day_diff + " days ago";
}

函数prettyDate（时间）{
变量日期=新日期（（时间| |“”）。替换（/-/g，“/”）。替换（/[TZ]/g，“”）），
diff=（（（新日期（））.getTime（）-Date.getTime（））/1000），
日差异=数学楼层（差异/86400）；
如果（isNaN（日差）| |日差<0）
返回；
返回日_diff==0&&(
差值<60&“刚刚”||
差值<120&“1分钟前”||
差异<3600和数学楼层（差异/60）+“分钟前”||
差值<7200&“1小时前”||
差异<86400和数学楼层（差异/3600）+“小时前”）||
day_diff==1&“昨天”||
日差<7日和日差+“日前”||
日差<31&&Math.ceil（日差/7）+“周前”||
day_diff+“几天前”；
}
Yeah@freejosh你说得对！非常感谢！！！
