Simplest solution is parseInt() .

<input type="number" onkeyup="this.value = parseInt(this.value); this.paste(this.onkeyup);"/>

ParseInt() returns blank(NaN) for E, e, +, - and anything which is not a number.

Use onkeyup and keydown according to your convenience. For me onkeyup works best, with copy-paste as well
