Restirct a catalog field to allow alphanumeric values and not special characters

KS13 — Wed, 04 Oct 2023 21:09:58 GMT

Hoping someone can guide me to write a simple onChange catalog client script.

Have a requirement, where a catalog field should allow alpha-numerical values and not allow special characters EXCEPT 'dashes' and 'dots/periods'

For example:

Allow: Test-123.com OR Test.123-456.

Restrict: Test-123$%^&.com

If allowed, set value, if Restricted, then throw an error message.

Thank you in advance

Hi @KS13

Below is the script.

var field_value = g_form.getValue('your_catalog_field'); // Replace 'your_catalog_field' with the actual field name. var regex = /^[a-zA-Z0-9.-]+$/; // Regular expression to allow alphanumeric, dashes, and dots. if (!regex.test(field_value)) { alert("Invalid input! Please use only alphanumeric characters, dashes, and dots."); }

You can also do this with Validation regex option for this.

Hi Amit,

Thank you for the guidance. It works partially. It won't throw the error.
