How to get info where uses textcursor is in TEXTAREA?

[Guest valokettu]

The problem is this:I have a textarea and a button that is supposed to create text to that point on textarea, where users (text)cursor is. I didn't find any variable or function from DOM that could do it... Have you guys any ideas how I could do this?This is the best solution that I have invented, but it only adds text to the end. Not there where users cursor is...:

<script language="javascript">function addlink() {  document.saveform.teksti.value=document.saveform.text.value + "<a href='WRITE ADDRESS HERE' target=_blank>WRITE TEXT HERE</a>";}</script><form method=POST action="editor.php?page=save" name="saveform"><table cellspacing=0 cellpadding=5 border=1> <tr>  <td> </td>  <td><input type=button value="Create link" onClick="addlink();"></td> </tr> <tr>  <td align=right>Text: </td>  <td><textarea name="text" rows=6 cols=50></textarea></td> </tr> <tr>  <td colspan=2 align=center><input type=submit value="Save"></td> </tr></table></form>
