在哪里可以找到有关在 JavaScript 中格式化日期的文档? [英] Where can I find documentation on formatting a date in JavaScript?

问题描述

我注意到 JavaScript 的 new Date() 函数在接受多种格式的日期方面非常聪明.

I noticed that JavaScript's new Date() function is very smart in accepting dates in several formats.

Xmas95 = new Date("25 Dec, 1995 23:15:00")
Xmas95 = new Date("2009 06 12,12:52:39")
Xmas95 = new Date("20 09 2006,12:52:39")

在调用 new Date() 函数时，我在任何地方都找不到显示所有有效字符串格式的文档.

I could not find documentation anywhere showing all the valid string formats while calling new Date() function.

这是用于将字符串转换为日期.如果我们看相反的一面，也就是将日期对象转换为字符串，直到现在我的印象是 JavaScript 没有内置 API 来将日期对象格式化为字符串.

This is for converting a string to a date. If we look at the opposite side, that is, converting a date object to a string, until now I was under the impression that JavaScript doesn't have a built-in API to format a date object into a string.

编者注:以下方法是提问者尝试在特定浏览器上运行但通常不起作用；查看此页面上的答案以了解一些实际解决方案.

今天，我在日期对象上使用了 toString() 方法，令人惊讶的是它用于将日期格式化为字符串.

Today, I played with the toString() method on the date object and surprisingly it serves the purpose of formatting date to strings.

var d1 = new Date();
d1.toString('yyyy-MM-dd');       //Returns "2009-06-29" in Internet Explorer, but not Firefox or Chrome
d1.toString('dddd, MMMM ,yyyy')  //Returns "Monday, June 29,2009" in Internet Explorer, but not Firefox or Chrome

同样在这里，我找不到任何关于我们可以将日期对象格式化为字符串的所有方式的文档.

Also here I couldn't find any documentation on all the ways we can format the date object into a string.

列出Date() 对象支持的格式说明符的文档在哪里?

Where is the documentation which lists the format specifiers supported by the Date() object?

推荐答案

我爱 10 种使用 JavaScript 格式化时间和日期的方法 和 处理日期.

基本上，你有三种方法，你必须自己组合字符串:

Basically, you have three methods and you have to combine the strings for yourself:

getDate() // Returns the date
getMonth() // Returns the month
getFullYear() // Returns the year

示例:

var d = new Date();
var curr_date = d.getDate();
var curr_month = d.getMonth() + 1; //Months are zero based
var curr_year = d.getFullYear();
console.log(curr_date + "-" + curr_month + "-" + curr_year);
