我有一个 Json 时间戳，我想使用 javascript 将其转换为简单的日期时间格式。

我需要以下格式的日期和时间:dd-mm-yyyy hr:mn

这是我希望提取时间戳的示例 json 日期:“时间戳”:1326439500

最佳答案

日期以纪元以来的毫秒数返回。下面的代码创建了一个 JS 日期对象:

var d = new Date(1245398693390);
var formattedDate = d.getDate() + "-" + (d.getMonth() + 1) + "-" + d.getFullYear();
var hours = (d.getHours() < 10) ? "0" + d.getHours() : d.getHours();
var minutes = (d.getMinutes() < 10) ? "0" + d.getMinutes() : d.getMinutes();
var formattedTime = hours + ":" + minutes;

formattedDate = formattedDate + " " + formattedTime;

这是 a working fiddle .

自很久以前发布此答案以来，发生了很大变化(尽管原始答案仍然有效)。在 ES6 引入 const/let 和模板字面量之后，一种更简洁的方法是:

const d = new Date(1245398693390);
let formattedDate = `${d.getDate()}-${d.getMonth()}-${d.getFullYear()}`;
const hours = d.getHours().toString().padStart(2, 0);
const minutes = d.getMinutes().toString().padStart(2, 0);
const formattedTime = `${hours}:${minutes}`;

formattedDate = `${formattedDate} ${formattedTime}`;

这是 a working fiddle .

您还可以通过稍微降低可读性来使代码更简洁:

function getFormattedDate()  {
    const padWithZero = (num, targetLength) => String(num).padStart(targetLength, '0');
    const d = new Date(1245398693390);
    return `${d.getDate()}-${d.getMonth()}-${d.getFullYear()} ${padWithZero(d.getHours(), 2)} ${padWithZero(d.getMinutes(), 2)}`;
}

这是 a working fiddle .

也可以使用 .toLocaleString() 并从中挑选出所需的元素。
