To block the +,-,e in input type number by using the following code.
<input type="number" id="input" />
<script> var input = document.getElementById("input"); var invalidChars = [ "-", "+", "e", ]; input.addEventListener("keydown", function(e) { if (invalidChars.includes(e.key)) { e.preventDefault(); } }); </script>
