Hello,
I have an HTML text field. I want to validate via JavaScript that the value entered is a valid date in the form of "MM/DD/YY" or "MM/D/YY" or "MM/DD/YYYY" or "MM/D/YYYY". Is there a function that does this?
I sort of assumed there was something like isNaN but I don't see anything. Is it true that JavaScript can't validate dates?
Is it true that JavaScript can't validate dates?
No.
Is there a function that does this?
No.
You will need to write your own validation function to parse the date format (regex comes to mind) and then determine if it is valid within your specific criteria.
Have you googled for something like javascript date validation? It shows up some good information, and a working code example here.
If you want to venture into the realms of JQuery there are plenty of validation plugins that include date validation. This plugin is one I've used a few times and has served me well.
