How is it possible to display (manually, without submit) the HTML element built in validation error message with Javascript?

Example:

    if(document.getElementById('id_checkbox').checked == false)
                    {
                       showBuiltInErrorMessage('id_checkbox'); --> "Please fill out this field"
                    }

Thanks for your help!

My bad, didn't notice the tag. – Anamnian Aug 08 '18 at 14:22
Thanks! That's exactly what i was looking for! document.getElementById('id_element').reportValidity(); is the key – Crema Aug 08 '18 at 14:25
