Browser autocompletion detection before selection

Question

In any case, can I detect autocomplete BEFORE the user selects an option from the drop-down list?

Expected: 400010as seen.

I currently have:

$('input').on('input paste change keyup', function(event) {
    if(event.type=='input'){
      console.log( $(this).val() ); 
    }
});

.. and it works AFTER the user has made a choice, but not earlier, as shown in the screenshot above.
