How can I prevent trailing periods in number inputs?

Question

I have the following HTML that prevents everything to be entered in a number search field, except for an ending period:

<input type="number" id="DrawingNumber" min="1" oninput="validity.valid||(value='');" />

For example, I can enter "1." or "111." etc. I would like it to prevent me from entering the ending period. It prevents me from entering everything else, such as leading zeroes, symbols, letters, except for the ending period.

Answer 1

<input type="number" id="DrawingNumber" 
       min="1" 
       onkeypress="return /\d/i.test(event.key)"
       oninput="validity.valid||(value='');" />
