title: Toggle the display of a text field with a checkbox
body: <p>When Unlimited is checked, remove the input box. That works. However, when the checkbox is unchecked the input box wont show back up.</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
      function getQuantity() {
          var checkbox = document.getElementById("unlimited");
          var qty = document.getElementById("quantityspace");
          if(checkbox.checked == true){
               qty.style.display = 'none';
          }else if(checkbox.checked == false) {
               qty.stlye.display = '&lt;input type="text" id="quantity" size="4" value="1" name="quantity" /&gt;';
          }
      }
  &lt;/script&gt;
  
  &lt;input type="checkbox" id="unlimited" name="unlimited" value="x" onClick="getQuantity(); " /&gt; Unlimited? &lt;span id="quantityspace"&gt;or specify:
  &lt;input type="text" id="quantity" size="4" value="1" name="quantity" /&gt;&lt;/span&gt;
  </code></pre>
