retrieving html code from an iframe to a textbox

[tecdesign]

Does anyone know how to take the html code of an Iframe and read this code in a text box?

 

Some examples of the code are here:

 

  function transfer_email()
{
var coding = iView.document.body.innerHTML;



document.getElementById('email_area').innerHTML = coding;

}

 

 

	<iframe id="iView" style="width: 415px; height:205px">
</iframe>

 

 

    <p>
      <input type="submit" name="Submit" value="Transfer to Email" onClick="transfer_email()">
</p>
    <p>
      <textarea name="textarea" cols="70" rows="15" id="email_area"></textarea>
    </p>
