My code is somewhat like this:

<?php

if($_REQUEST['post'])
{
    $title=$_REQUEST['title'];
    $body=$_REQUEST['body'];
    echo $title.$body;
}
?>

<script type="text/javascript" src="texteditor.js">
</script>

<form action="" method="post">
       Title: <input type="text" name="title"/><br>

       <a id="bold" class="font-bold"> B </a> 
       <a id="italic" class="italic"> I </a>

       Post: <iframe id="textEditor" name="body"></iframe>

       <input type="submit" name="post" value="Post" />
</form>

the texteditor.js file code is:

$(document).ready(function(){
document.getElementById('textEditor').contentWindow.document.designMode="on";
document.getElementById('textEditor').contentWindow.document.close();
$("#bold").click(function(){
 if($(this).hasClass("selected"))
 {
    $(this).removeClass("selected");
 }else
 {
    $(this).addClass("selected");
 }
 boldIt();
 });
 $("#italic").click(function(){

 if($(this).hasClass("selected"))
 {
  $(this).removeClass("selected");
  }else
  {
  $(this).addClass("selected");
  }
  ItalicIt();
  });


   });

   function boldIt(){
   var edit = document.getElementById("textEditor").contentWindow;
   edit.focus();
   edit.document.execCommand("bold", false, "");
   edit.focus();
   }

   function ItalicIt(){  
   var edit = document.getElementById("textEditor").contentWindow;
   edit.focus();
   edit.document.execCommand("italic", false, "");
   edit.focus();
   }

   function post(){
var iframe = document.getElementById("body").contentWindow;
    }

actualy i want to fetch data from this texteditor (which is created using iframe and javascript) and store it in some other place. i'm not able to fetch the content that is entered in the editor (i.e. iframe here).

please help me out of this....
