If you want to trigger the event as you type, use the following:

$('input[name=myInput]').on('keyup', function() { ... });

If you want to trigger the event on leaving the input field, use the following:

$('input[name=myInput]').on('change', function() { ... });

You can do this in different ways, keyup is one of them. But i am giving example below with on change. 

$('input[name="vat_id"]').on('change', function() {
    if($(this).val().length == 0) {
        alert('Input field is empty');
    }
});

NB: input[name="vat_id"] replace with your input ID or name.
