Yes, here's how I did it for the vB Spell, this is just a portion, you can download the entire code from the vB Spell hack

        if (window.opener.document.getElementById(spell_fieldname + '_iframe') == null)
        {   
                if (window.opener.document.getElementById(spell_fieldname + '_textarea').innerHTML == '')
                {
                        window.opener.document.forms[spell_formname]["message"].value = mispstr;
                }
                else
                {
                        var oHtml = window.opener.document.getElementById(spell_fieldname + '_textarea');
                        oHtml.innerHTML = mispstr;
                }
        }
        else
        { 
                var iframe = window.opener.document.getElementById(spell_fieldname + '_iframe');
                var iframedoc = iframe.contentWindow.document;
                var oHtml = iframedoc.body;
                
                oHtml.innerHTML = mispstr;      
        }
