I'm having trouble using pattern matching with RegEx for client-side validation. No problem with the other validations so far.
I need to make sure users search for a particular pattern in a code - 4 digits that can include leading zeros for example: 0004 , 0104

I thought that this expression would do it: \d{4}
but no validation occurs. \d\d\d\d lets everything thru as well.
Then I tried quite a few other simple regexes to test the system but all entries are accepted.

Hi David,
As per your pattern you should use: (^([0-9]{4})$)

Hi Teodor

(^([0-9]{4})$) or ^[0-9]{4}$ still lets anything thru.
For example I can enter "xyz" and the input field does not reject with an error message.

As I said earlier, I've also tested a few other simple regexes with this input field and nothing is rejected.

Number Validation validates perfectly, but obviously with no leading zeros.

Hello David,
With the validation pattern i provided "xyz" does not get through ....

Thanks Teodor - working now.
In all my troubleshooting, I managed to delete the type = "text" attribute.
Added this back then it validates. But if the input tag does not have a type attribute, it should default to "text" anyway.
