           Summary: window.getSelection() doesn't work in textareas
           Product: WebKit
           Version: 420+ (nightly)
          Platform: Macintosh
        OS/Version: Mac OS X 10.4
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: JavaScript
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: stamm at salesforce.com

window.getSelection() returns null when the selection is in a text area.  This
behavior makes it very difficult when there are two text areas on the page. 
Since the selection for a text area remains when you leave it, you have no idea
which one of the text areas is the current (or last one) selected.

In the latest nightly build, when I try the page below, if you select the
"Random Text" and then click dump range, you will get a real range object.  If
you select the "My text" inside the text area, you get null for a range object.
 You can fake it using getSelectionRange, but that doesn't work.  

1.  Select "text" inside the text area
2.  Select "random" 
3.  Click "Copy TextArea Sel".  This contains the last selection.  Even though
random was selected.

If I would add another text area, I would have no idea what the user has

<meta http-equiv="Content-type" content="text/html" />
<title>Simple Selection Test</title>
function dumpO(o) {
  var msg = "";
  var i = 0;
  for (var f in o) {
    try {
      msg += f + " = " + o[f] + "\n";
    } catch (e) {}
    if (i++ == 10) {
       msg = "";
  if (msg) alert(msg);
function getSelectionRange(o) {
  var start = o.selectionStart;
  var end = o.selectionEnd;
  return o.value.substring(start,end);

<button onclick="document.getElementById('r').innerHTML =
          window.getSelection();"><u>Copy Window Sel</u></button><br>
<button onclick="document.getElementById('r').innerHTML =
                 TextArea Sel</u></button><br>
<button onclick="dumpO(window.getSelection());"><u>Dump
<button onclick="dumpO(window.getSelection().getRangeAt(0));"><u>Dump
<button onclick="document.getElementById('r').innerHTML =
window.getSelection().getRangeAt(0);"><u>Copy Range</u></button><br>
<button onclick="dumpO(document.getElementById('text'));"><u>Dump
<button onclick="dumpO(window);"><u>Dump Window</u></button><br>
<textarea id="text" name="text" rows="20" cols="80"/>
My text</textarea>
<div id="r">divMe</div>
Random Text
