Regex - Starts with specific text and ends with number on Change

[piyushnector]

Hello,

I am looking for a solution on below - 

There is a field in the catalog item in which the user should only allow to enter specific text (STARTS with "ADA") and ends with a number. No special symbol is allowed.

This should be an immediate response, if the pattern does not match we should be getting an error (popup) message.

Example Text: ADARegionCountry5004

Regards,

Piyush Kumar

Hi @piyushnector ,

Below is the code snippet for your reference.

In the client script please change the "u_text_field" value to the variable name on which you want to validate.

Thank you that works, but how can I ignore the case bcoz if user tried to fill it in lower case this will give error

Hi @piyushnector ,

To make the regular expression case-insensitive, you can add the "i" flag at the end of the regular expression pattern. This will allow it to match both uppercase and lowercase letters.

Update this line var pattern = /^ADA.*\d$/;  to  var pattern = /^ADA.*\d$/i;

Please mark as helpful and correct solution

What would  var pattern look like if you needed to require the characters "-SA" at the end?

I tried the following, but it doesn't work:

var pattern = /^.*\d-sa/i;
