Regex in onchange catalog client script

[tsoct]

The catalog client script should retrieve the regex pattern from the country's table and compare it to the input in the 'account_format' variable.

However, the script below is not working. I confirmed that the regex pattern is correct, however it does not display a warning message when the input value is incorrectly formatted.

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var ctry = g_form.getValue('bank_country');

    var rec = new GlideRecord('core_country');
    rec.addQuery('sys_id', ctry);
    rec.query(function() {
        if (rec.next()) {
            var pattern = rec.u_pattern; //pattern = regex format stored as string

            if (!pattern.test(newValue)) {
                alert('Invalid input');
                g_form.clearValue('account_format');

            }
        }
    });

}

It's strongly advised to not use GlideRecord client side and instead use GlideAJAX. However to resolve your query:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var ctry = g_form.getValue('bank_country');

    var countryGR = new GlideRecord('core_country');
    countryGR.setLimit(1);
    countryGR.query('sys_id', ctry, function(responseGR) {
        if (!responseGR.next())
            return alert("No Record Found");

		var pattern = responseGR.u_pattern;
		console.log("Found pattern of " + pattern);

		if(!pattern.test(g_form.getValue('field_name_here'))){
			alert("Invalid input");
		}
    })
}

Thanks but this is not returning any alert on wrong input

Did you check your browser console, the below will let you know whether a pattern is found

console.log("Found pattern of " + pattern);
