2nd October 2020: note that many bare-bones approaches are fraught with subtle bugs (eg. whitespace, implicit partial parsing, radix, coercion of arrays etc.) that many of the answers here fail to take into account. The following implementation might work for you, but note that it does not cater for number separators other than the decimal … Read more
You don’t need the date validator. It doesn’t support dd/mm/yyyy format, and that’s why you are getting “Please enter a valid date” message for input like 13/01/2014. You already have the dateITA validator, which uses dd/mm/yyyy format as you need. Just like the date validator, your code for dateGreaterThan and dateLessThan calls new Date for … Read more

You have some sort of invisible character that the validator is choking on somewhere (ie. it looks and acts like a space, but it isn’t the space). If I view your CSS file directly and copy/paste the contents into the CSS validator’s direct input validation, it validates
Currently, UUID’s are as specified in RFC4122. An often neglected edge case is the NIL UUID, noted here. The following regex takes this into account and will return a match for a NIL UUID. See below for a UUID which only accepts non-NIL UUIDs. Both of these solutions are for versions 1 to 5 (see the … Read more
I’m new to jQuery and was wondering how to use it to validate email addresses.
Since .NET 4.5 the Validators use data-attributes and bounded Javascript to do the validation work, so .NET expects you to add a script reference for jQuery. There are two possible ways to solve the error: Disable UnobtrusiveValidationMode: Add this to web.config: It will work as it worked in previous .NET versions and will just add the … Read more
