Get currently selected text field ID and add text to it through a numberpad

Question

So, I have this table where I have text field beside each product and I am to input the value in any selected text field via a number pad( buttons from 0-9). I need to know how can I get the id value of currently selected text field, and add numbers as text to it using the numberpad.

You need to use this.id to get the ID of the particular element. For example, when I have done a snippet that says the ID once you press Enter key.

<input id="this-is-id"
       onkeyup="if (event.keyCode == 13) alert(this.id);" />
