hide VAT field if company name is empty

Replies: 0

Hello!
Wanted to hide the VAT field if the company field is empty (due to business logics)
Tried:

let input = document.getElementById("billing_company")

  input.oninput = function() {
    if (input.value.length === 0) {
        console.log('empty!')
    document.getElementById('vat_number_field').style.display = 'none';
    }
    document.getElementById('vat_number_field').style.display = 'block';
  };

but it does not working. Any ideas?

PS found this topic:

but still not working for me.
