c# - Flex/Flash/Java/C# 中的漂亮日期文本

Question

是否有免费的库或类可以以漂亮的方式格式化日期，例如“5 分钟前”或“昨天”？

我对可以移植到 Actionscript(如 Java 或 C#)的另一种语言的相同代码感到满意

Answer 1

这有帮助吗？应该很容易移植到 AS3。

// Takes an ISO time and returns a string representing how
// long ago the date represents.
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";
}

// 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 );
        });
    };
