Regex to validate 'GITO_ESA_TC_090' format

[Ankita9793]

Hi All,

Can someone please help me with Regex to validate below format.  Field should basically accept only below format. 

GITO_ESA_TC_090

@Ankita9793 Please try this Regex.

/^[A-Z]{4}_[A-Z]{3}_[A-Z]{2}_[0-9]{3}$/gm

Hope this helps.

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

    var pattern = /^GITO_ESA_TC_\d{3}$/;
    
    if (!pattern.test(newValue)) {
        g_form.showFieldMsg('your_field_name', 'Invalid format. Please use the format: GITO_ESA_TC_###', 'error');
    } else {
        g_form.hideFieldMsg('your_field_name');
    }
}
