如何格式化JSON日期？

从webservice解析日期

对不起，如果此问题已被询问。我环顾四周，但找不到一个。有没有一个快捷方便的方式来将 json 日期转换为仅使用 javascript 和 jQuery的人性化格式（不包括额外的 jQuery 库）？

Sorry if this question has already been asked. I have look around but have been unable to find one. Is there a quick and convenient way to convert a "json" date into a human friendly format using only javascript and jQuery (excluding additional jQuerylibraries)?

日期格式如下：

creationDate: "/Date(1346713200000+0100)/"

谢谢

推荐答案

> var maybeDateString = "/Date(1346713200000+0100)/";
> fromDateString(maybeDateString)
Tue Sep 04 2012 02:00:00 GMT+0200

function fromDateString(str) {
    var res = str.match(/\/Date\((\d+)(?:([+-])(\d\d)(\d\d))?\)\//);
    if (res == null)
        return new Date(NaN); // or something that indicates it was not a DateString
    var time = parseInt(res[1], 10);
    if (res[2] && res[3] && res[4]) {
        var dir = res[2] == "+" ? -1 : 1,
            h = parseInt(res[3], 10),
            m = parseInt(res[4], 10);
        time += dir * (h*60+m) * 60000;
    }
    return new Date(time);
}
