Service Catalog Variable that has "Validation Regex" in Place vs. onChange Script

[MG Casey]

If a service catalog variable has "Validation Regex" on it, has anyone figured out how to tell if the field is not passing validation if it has a corresponding "onChange" client script?

Of course, I can just repeat the previously used Regex within my "onChange" client script, but ideally, I thought there would be a property of the field that I could check, so I would know not to continue with my "onChange" client script if the new field value itself isn't even passing the "Validation Regex" set in place.

Hello @MG Casey 

Unfortunately there isn't a easy way to do this. Some work around is possible like 

• Solution 1: As you mentioned Repeat the Regex in the Client Script

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue === '') {
        return;
    }

    // Regex pattern (same as the one in Validation Regex)
    var regex = /^[A-Za-z0-9]+$/; // example pattern, update accordingly
    if (!regex.test(newValue)) {
        g_form.showFieldMsg('variable_name', 'Invalid input. Please correct the format.', 'error');
        return;
    }

    // Continue with the rest of the onChange logic if input is valid
    // Your additional logic here
}​

• Solution 2: Use isValidRecord() (Custom Solution)

  Another approach is to write a Script Include that checks the validity of the field against the server-side Validation Regex. You can then call this script from your client script using a GlideAjax call. However this is not recommended.

Ya, that's too bad, so solution 1 is what I had already ended up doing.
