title: Disable page refresh
body: <p>I need to prevent users from refreshing a page.</p>
  
  <ol>
  <li>I have scripted in such a way that there is no 'forward' or 'backward' movement required.</li>
  <li>However, if one refreshes the page, 'everything' starts from the beginning.
  <ul>
  <li>To save everything before page refresh and restore them after is not ideal.</li>
  </ul></li>
  <li>In order to prevent page refresh, I could use an <code>alert();</code>, but there are chances that the user might neglect the warning.</li>
  <li>Any other choices...???</li>
  </ol>
