title: text disappears rapidly after click on 'submit-button'
body: <p>Got a problem. this is my code:</p>
  
  <pre><code>&lt;html&gt;
  
  &lt;body&gt;
  &lt;form&gt;
  &lt;p&gt;13-7: &lt;input id="in1" type="text"" /&gt;&lt;input type="submit" onclick="check(6, 'in1', 'out1')" value="Tjek!"/&gt;&lt;/p&gt;
  &lt;p id="out1"&gt;&lt;/p&gt;
  &lt;p&gt;20-7: &lt;input id="in2" type="text"" /&gt;&lt;input type="submit" onclick="check(13, 'in2', 'out2')" value="Tjek!" /&gt;&lt;/p&gt;
  &lt;p id="out2"&gt;&lt;/p&gt;
  
  
  
  &lt;script type="text/javascript"&gt;
  
  function check(facit, input, output) {
      var answer, evaluation;
      answer = document.getElementById(input).value;
      evaluation = (answer == facit) ? "Correct" : "Wrong";
      document.getElementById(output).innerHTML = evaluation;
      return false;
  }
  
  &lt;/script&gt;
  &lt;/form&gt;
  &lt;/body&gt;
  
  &lt;/html&gt;
  </code></pre>
  
  <p>When I click the submit-button, the 'correct/wrong' shows only for a moment. I want it to stay on the site, any advice?</p>
