转换C＃日期时间为Javascript日期 [英] Convert C# DateTime to Javascript Date

问题描述

我在Javascript从MVC收到一个C＃日期时间的函数。
如果日期为null，则它应该返回 - ，如果它是一个有效的日期就应该返回格式化日期

I have a function in Javascript that receives a C# DateTime from MVC. If the date is null it should return "-", if it's a valid date it should return the formated date.

重要提示：这是不可能送该日期从C＃另一种格式

IMPORTANT: It's not possible to send the date in another format from C#.

使用Javascript：

Javascript:

function CheckDate(date) {

  if (date == "Mon Jan 01 0001 00:00:00 GMT+0000 (GMT Daylight Time)")
    return "-";
  else {
    var dat = new Date(date);
    return dat.getFullYear() + dat.getMonth() + dat.getDay();
  }

有没有更好的方式来比较，如果日期是C＃新的datetime？

Is there a better way to compare if the date is the C# New DateTime?

和我怎么分析，并在YYYY / MM / DD格式？

And how do I parse and return the date in "yyyy/MM/dd" format?

推荐答案

由于你坚持的输出，我想不出什么更好的方式来在JavaScript端抓到的的DateTime 0

Given the output you're stuck with, I can't think of any better way to catch a DateTime of 0 on the javascript side.

Date.parse 应努力为您解析的需求，但它返回的毫秒数，所以你需要环绕它Date构造函数：

Date.parse should work for your parsing needs, but it returns number of milliseconds, so you need to wrap a Date constructor around it:

var date = new Date(Date.parse(myCSharpString));

<击>对于归期，你只是想

For the return date, you simply want

date.getFullYear() + "/" + (date.getMonth() + 1) + "/" + (date.getDate() + 1);

（ date.getMonth 和 date.getDate 0被索引，而不是1索引）

(date.getMonth and date.getDate are 0-indexed instead of 1-indexed.)

修改
由于JoeB的渔获量，让我做了修正。在 date.getMonth（）函数0索引，但 date.getDate（）函数1索引。小提琴是工作与+1因为date.getMonth工作在当地的时间，这是UTC前。我没有正确检查文档，并且只是增加1，并将其与小提琴合作

EDIT Thanks to JoeB's catch, let me do a correction. The date.getMonth() function is 0-indexed, but the date.getDate() function is 1-indexed. The fiddle was "working" with the +1 because date.getMonth works in local time, which is before UTC. I didn't properly check the docs, and just added 1, and it worked with the fiddle.

要做到这一点更正确的方法是：

A more proper way to do this is:

有关归期，你只是想

date.getFullYear() + "/" + (date.getMonth() + 1) + "/" + (date.getUTCDate());

（ date.getMonth 为0索引。而 date.getDate 为1索引，但容易受时区差异）

(date.getMonth is 0-indexed while date.getDate is 1-indexed but susceptible to time-zone differences.)
