Date Validation in Nodejs
提问by Saransh Mohapatra
I want the user to input his date of birth. And I would want it be in format YYYY-MM-DD. Node-Validator right now validates all date format, not a particular format. So If I input 12324433 , it is also validated as it thinks its epoch time.
我希望用户输入他的出生日期。我希望它采用 YYYY-MM-DD 格式。节点验证器现在验证所有日期格式，而不是特定格式。所以如果我输入 12324433 ，它也会被验证，因为它认为它的纪元时间。
Please help me out as to what should I do? This question is specific to validation in Mongoose
请帮我看看我该怎么办？此问题特定于 Mongoose 中的验证

I'm a big fan of express-form, def worth a look -- you can also use moment.js. I've used it myself a for this very reason
我是 的忠实粉丝express-form，绝对值得一看——你也可以使用moment.js. 出于这个原因，我自己使用了它
from moment.js docs:
来自 moment.js 文档：
moment("2011-10-10", "YYYY-MM-DD").isValid(); // true
moment("2011-10-50", "YYYY-MM-DD").isValid(); // false (bad day of month)
Cheers, I hope this helps :)
干杯，我希望这有帮助:)

As Node-Validator's documentation points out, "regex is probably a better choice". I whipped up a regex that looks pretty good, and I believe it'll get the job done, but I advise you to test it thoroughly, if you plan to use it.
正如 Node-Validator 的文档所指出的那样，“regex 可能是更好的选择”。我创建了一个看起来不错的正则表达式，我相信它可以完成工作，但我建议你彻底测试它，如果你打算使用它。
/\d\d\d\d-(0[1-9]|1[0-2])-(0[1-9]|[1-2]\d|3[0-1])/
This regex will validate a date in the format YYYY-MM-DD, that you need. You can see a working code snippet that uses it here: http://tinker.io/c269b/
此正则表达式将验证您需要的格式为 YYYY-MM-DD 的日期。您可以在此处看到使用它的工作代码片段：http: //tinker.io/c269b/
Good luck!
祝你好运！
Edit:I noticed something that breaks it. This regex validates partial matches, so an input like "1970-01-011" checks out as valid. This happens because I forgot to add the startand endmarkers inside the regex. This is how it looks after I fixed it:
编辑：我注意到一些东西打破了它。此正则表达式验证部分匹配，因此像“1970-01-011”这样的输入检查为有效。发生这种情况是因为我忘记在正则表达式中添加开始和结束标记。这是我修复后的样子：
/^\d\d\d\d-(0[1-9]|1[0-2])-(0[1-9]|[1-2]\d|3[0-1])$/
The example on Tinker is also updated with the fix.
Tinker 上的示例也更新了修复程序。

Since I was also looking into this and was checking express validator as well, I mocked up a regex as well that might help you out with validating dates.
因为我也在研究这个并且也在检查快速验证器，所以我模拟了一个正则表达式，它可能会帮助你验证日期。
((19|2\d)\d\d)-((0?[1-9])|(1[0-2]))-((0?[1-9])|([12]\d)|(3[01]))
