[RESOLVED] Javascript/RegEx : \d{2,4}

I'm using this code to validate a date

Code:

---

if ( testStr.match(/^\d{1,2}\/\d{1,2}\/\d{2,4}$/) == null )
{
        sMessage += 'Date is not in format DD/MM/YYYY';
        document.getElementById('startdate').focus();
}

---

Now, I have a limited understanding of Regular Expressions but doesn't \d{2,4} mean that it matches either 2 or 4 numeric characters? Because it seems to be accepting 3 numeric characters too. :confused:

You're right, but I'm not sure why it's not working. So as a last resort, use

d{4} instead of d{2,4}

Okay. Thanks anyway :) It could just be a FireFox issue.

\d{2,4} means atleast 2 digits, no more than 4. You could try \d{2}|\d{4}. That should give you what you want. You may need to wrap it in a parenthesis.

Ahhh I see. Thanks :)
