title: event problem in Firefox
body: <p>I have a problem accessing the 'event' in Firefox. The following code works fine in Chrome, but in Firefox I get a "event is not defined" error.</p>
  
  <pre><code>&lt;tr onclick="rowSelected('thisRowType')"&gt;
    ... row content ...
  &lt;/tr&gt;
  
  &lt;script type="text/javascript"&gt;
      function rowSelected(type) {
          var eventRow = event.currentTarget; // here I get the error
      }
  &lt;/script&gt;
  </code></pre>
  
  <p>I understand that Firefox does not find any variable called event, but I have not been able to find anything other than 'event' should also be defined in Firefox.</p>
  
  <p>So how could I access the current event in Firefox, or how should a redesign look like?
  Please note that I have different rows supplying different values for 'type'.</p>
