Check date format in JavaScript

Question

I would like to check if the date format is (dd/mm/yyyy) before the post is made in a JavaScript (jQuery).

How could I achieve that?

You can use a regex:

/^\d{2}\/\d{2}\/\d{4}$/.test(str)

Of course this will not check for a valid date, but in that case you can always let your server-side code throw an error. If you want more client-side validation have a look at Javascript: how to validate dates in format MM-DD-YYYY?; it is easy to adapt to your format.

Thanks it's working. I knew that regex could help but... damn that regex is hard to understand :P

Oops, just fixed it - looks like nobody who upvoted it noticed that I forgot to escape the slashes. The regex is pretty easy btw: ^$ mark the start/end of the string, \d is a digit, {2} means that you want exactly two occurrences.

i think that would be very difficult, considering the ambiguity for cases where the date is less than equal to 12
