Is this to validate input for a variable in a Catalog item?

If so, I would recommend you create a regular expression and use it to validate the value.

Navigate to: Service Catalog > Catalog variables > Variable Validation Regex

Create a new record, input the expression you have, and then use that new record to validate the input on your Catalog variable.

I tested and it works with both new RegExp("^[a-zA-Z0-9]*$"); and /^[a-zA-Z0-9]*$/.

The only thing is it also accepts just characters for ex 'abcd'. Is that were it fails for you.

var abc = 'abcd123';

var patt = /^[a-zA-Z0-9]*$/;

gs.info(patt.test(abc));
