title: How to disable/enable a button with a checkbox if checked
body: <p>Please i need a script that can work with the HTML code bellow to disable/enable the button when a checkbox is checked or unchecked, </p>
  
  <p><code>&lt;input type="submit" name="sendNewSms" class="inputButton" id="sendNewSms" value="    Send    " /&gt;</code></p>
  
  <p>please pals i don't mean the button to be disabled when checked, but rather the other way round.</p>
