使用moment.js将日期转换为UTC [英] Convert date to UTC using moment.js

问题描述

可能很容易回答这个问题，但我似乎找不到让moment.js以毫秒为单位返回UTC日期时间的方法。以下是我正在做的事情：

Probably and easy answer to this but I can't seem to find a way to get moment.js to return a UTC date time in milliseconds. Here is what I am doing:

var date = $("#txt-date").val(),
    expires = moment.utc(date);

知道我做错了吗？

推荐答案

可在文档中找到 。有了类似于时刻的图书馆，我恳请您阅读完整的文档。它非常重要。

This is found in the documentation. With a library like moment, I urge you to read the entirety of the documentation. It's really important.

假设输入文本是根据用户的当地时间输入的：

Assuming the input text is entered in terms of the users's local time:

 var expires = moment(date).valueOf();

如果指示用户实际输入UTC日期/时间，则：

If the user is instructed actually enter a UTC date/time, then:

 var expires = moment.utc(date).valueOf();
