Answer 1

Check the link Regular Expression Demo

use the below reg exp

[a-z] + [^0-9\s.]+|.(?!\d)

Answer 2

Use this:

document.getElementById(target).value = newVal.replace(/[^0-9.]/g, "");

Answer 3

Removing only decimal part can be done as follows:

number.replace(/(\.\d+)+/,'');

This would convert 13.6667px into 13px (leaving units px untouched).

Answer 4

Try this:

document.getElementById(target).value = newVal.replace(/^\d+(\.\d{0,2})?$/, "");
