Prevent the negative value in number fields even iphan (-) and character (e) in number input type

If we use number type in input field. In this case it will allows the characters are (e) and (-). Here we can restrict that character while we do input.


Solution:


Keycodes: e : 69, - : 189


<input type="number" onkeydown="return event.keyCode !== 69 && event.keyCode !== 189" />


Reference for keycode finder :
