onkeydown event - Firefox

Asked by: Batalf

Dear all experts!

This is a Firefox related question.

Can someone show me how to dynamically add a keydown event to the iframe in the code below, so that the updateTa() function is executed and the text area updated with the HTML code of the iframe?

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<head>
      <title>My DHTML Editor</title>
      <style type="text/css">
      #DHTMLEditor,#DHTMLsrc{
            width:500px;
            height:500px;

      }
      #DHTMLsrc{

      }
      #DHTMLEditor{
            border:1px solid #000000;
            margin:0px;
      }
      </style>
      <script type="text/javascript">
      var bodyRef;
      var taRef;
      var editorRef;
      function updateTa(){ // THIS FUNCTION IS NEVER EXECUTED ON FIREFOX - WHY?
            taRef.value=bodyRef.innerHTML;
            alert('hello');
      }
      function initEvents(){
            bodyRef.onkeyup=updateTa; // THIS DOESN'T WORK ON FIREFOX
      }

      function editorInit(){
            taRef = document.getElementById('DHTMLsrc');
            if(!document.all){
                  document.getElementById("DHTMLEditor").contentDocument.designMode="on";
                  bodyRef= document.getElementById("DHTMLEditor").contentDocument.body;
                  editorRef= document.getElementById("DHTMLEditor");
                  bodyRef.innerHTML = document.getElementById('DHTMLsrc').value;
            }else{
                  bodyRef = document.getElementById("DHTMLEditor");
                  editorRef = document.getElementById("DHTMLEditor");
                  bodyRef.innerHTML = document.getElementById('DHTMLsrc').value;
            }
            initEvents();
      }
      window.onload = editorInit;
      </script>
</head>
<body>
            <iframe frameborder="0" marginheight="0" marginwidth="0" id="DHTMLEditor"></iframe>
            <textarea id="DHTMLsrc">Init <b>Content</b> is comming here</textarea>

</body>
</html>
