Script error

[fnsbe]

Hi everybody,

First of all I'm not a java hero but I tried to write my own text editor.
Everything works but only when the existing text need to be re-edited the butttons of my editor seem not to work anymore...

This is the main script :

<!--
  function storeCaret (txtarea) { 
    if (txtarea.createTextRange) { 
      selectedRange = document.selection.createRange().duplicate();
      selectedInputArea = txtarea;
    } 
  } 
 
  function WrapIE(txtarea, lft, rgt) {
    strSelection = document.selection.createRange().text;
    if (strSelection!='') {
      document.selection.createRange().text = lft + strSelection + rgt;
      var range = document.selection.createRange();
      range.collapse(true);
      range.moveStart('character', lft.length+strSelection.length+rgt.length);
      range.select();
      storeCaret(txtarea)
    }
    txtarea.focus();
  }
 
  function wrapMoz(txtarea, lft, rgt) {
    var selLength = txtarea.textLength;

    var s1 = (txtarea.value).substring(0,selStart);
    var s2 = (txtarea.value).substring(selStart, selEnd)
    var s3 = (txtarea.value).substring(selEnd, selLength);
    txtarea.value = s1 + lft + s2 + rgt + s3;
    txtarea.focus();
    var cPos=s1.length+(lft.length+s2.length+rgt.length);
    txtarea.setSelectionRange(cPos,cPos);
  }
 
  function wrapTag(txtarea, lft, rgt) {
      lft = unescape(lft);
      rgt = unescape(rgt);
    if (document.all) {
      WrapIE(txtarea, lft, rgt);

      caretPos.text = caretPos.text.charAt(caretPos.text.length - 1) == ' ' ? text+caretPos.text + ' ' : text+caretPos.text;
    } else {
      txtarea.value = txtarea.value + text; 
    }
    txtarea.focus();
    return;
  }

The Error part follows in the next window...

[fnsbe]

Now... The user sends this text into a database. When he wants to edit the existing text he clicks a button and a layer, that was hidden, appears. The layer shows the same kind of editor with the existing text in it.
Everything works... but my java buttons don't...

This is the layer with the editor that doesn't work properly :

<div id="edittekst<?php echo $paragr['artikel_id']?>" style="position:absolute; width:400px; height:100px; z-index:4; visibility: hidden; left:300px;" class="layer">

First off, I think this is in the wrong forum. This is JavaScript, not Java - there is a HUGE difference.

But, here is an answer anyway:

In the editor that works, this.parentNode .parentNode refers to the form tag - which is the parent of the textarea named "txt". This code works.

The problem is in the other half of your code. Here, this.parentNode .parentNode refers to the tr element - which is NOT the parent of the textarea named "newtxt".

You would do better to use document.getEle mentByID(), since your textareas use the id attribute. This would keep you from having to crawl up the DOM tree to find your textarea.
