title: Replace non-numeric characters with JavaScript?
body: <p>I use the regular expression <code>/^\+(90)[2-5]{1}[0-9]{9}$/</code> for phone validation, but when someone enters any special characters (such as <code>*</code> <code>-</code> <code>/</code> <code>(</code> <code>)</code> <code>-</code> <code>_</code>) in the input, I want to replace the characters with an empty string (remove them). Note that I don't want to replace the <code>+</code>.</p>
  <p>How can I do that?</p>
