Regular expression for date in dd/mm/yyyy format for javascript validation
提问by Ratnesh Lal
I have to do client side validation(using javascript/JQuery) for the input value which should have date in dd/mm/yyyy format. Please share regular expression if exist. It should validate the date is proper in all context.
我必须对应该具有 dd/mm/yyyy 格式的日期的输入值进行客户端验证(使用 javascript/JQuery)。如果存在,请分享正则表达式。它应该验证日期在所有上下文中是否正确。
Thanks in advance, Ratnesh

/^[0-9]{4}\-(0[1-9]|1[012])\-(0[1-9]|[12][0-9]|3[01])/
or look at this the same question
或者看看这个同样的问题

As an alternative to regular expressions you may wish to take a look at datejs
作为正则表达式的替代方案,您可能希望查看 datejs
Using parse exact http://code.google.com/p/datejs/wiki/APIDocumentation#parseExact
使用解析精确http://code.google.com/p/datejs/wiki/APIDocumentation#parseExact
you can do things like:
您可以执行以下操作:
var myDate = Date.parseExact("19/12/2004", "dd/mm/yyyy");
And will return null, if the date cannot be parsed.
如果无法解析日期,则返回 null。
n.b. I haven't tested the code above, but it should work ok.
nb 我还没有测试上面的代码,但它应该可以正常工作。

Use
用
^(0?[1-9]|[12][0-9]|3[01])[\/\-](0?[1-9]|1[012])[\/\-]\d{4}$
I was looking for the same thing and got it from here
我正在寻找同样的东西并从这里得到它
This expression validates days from 01 to 31, months from 01 to 12 but it accepts any number with 4 digts for year (including 0000). And it returns true for wrong dates like 31/02/2015.
此表达式验证从 01 到 31 的天数,从 01 到 12 的月数,但它接受任何带有 4 位数字的年份(包括 0000)。对于错误的日期,例如 31/02/2015,它返回 true。
Use a regex online validator like this onein order to check if it suits you.
使用像这样的正则表达式在线验证器来检查它是否适合您。

A lot of this in google. You should have tried to find it at least.
谷歌中有很多这样的东西。你至少应该试着找到它。

Regex will validate your format, but won't validate if date makes logic sense (leap years and stuff). That's said:
正则表达式将验证您的格式,但不会验证日期是否符合逻辑(闰年之类的)。那是说:
Javascript date regex DD/MM/YYYYjavascript regexp, validating date problem
Javascript 日期正则表达式 DD/MM/YYYY javascript正则表达式,验证日期问题
and numerous others...
和许多其他人......
