如何在java脚本中检查字符串是否为日期时间类型。 [英] How to check if a string is date time type in java script.

问题描述

Please don't mark this as the duplicate. I found many answers to check if string is of type date without adding any jquery libraries.But Couldn't find anything. 

function IsDate() { var date = "26.02.2016 11:48:36"  return Date.Parse(new Date("26.02.2016 11:48:36")); }

The above code says the date is invalid but it is a valid date. Can any one please let me know how to check this kind of string value as date type in Jquery/Javascript? 

我的尝试：

What I have tried:

Many Solutions suggested to use Date.Parse() method or use datejs external library. For the string "26.02.2016 11:48:36" but the Date.Parse() method returns "Nan" where as it had to say as valid date.

推荐答案

JavaScript Date.parse（）接受 RF 2822 [ ^ ]或https://www.w3.org/TR/NOTE-datetime格式 - 你的字符串都不是......

JavaScript Date.parse() accepts dates in RF 2822[^] or https://www.w3.org/TR/NOTE-datetime format - your string is none of them...

你好！



你应该注意的几件事：

> Date.Parse不是有效的javascript函数，而不是使用Date.parse，返回no。从1970年1月1日到指定日期之间的毫秒数。



> Javascript不支持dd / mm / yyyy格式。因此，您的代码可能会返回无效日期。所以，使用mm / dd / yyyy格式而不是。

Hello there!

Few things you should mind:
> Date.Parse is not a valid javascript function instead of use Date.parse and this return no. of millseconds between 1/1/1970 and to specified date.

> Javascript doesn't support dd/mm/yyyy format. So, your code might return Invalid date. So, use mm/dd/yyyy format instead of that.

var date = "02.26.2016 11:48:36"  

	if(!isNaN(Date.parse(date)))
	{
		document.write("Valid Date \n");
	}
