removing html, head, body tag inside TinyMCE
plugins: [
"advlist autolink autosave link image lists charmap print preview hr anchor pagebreak spellchecker",
"searchreplace wordcount visualblocks visualchars code fullscreen insertdatetime media nonbreaking",
"save table contextmenu directionality emoticons template textcolor paste fullpage textcolor colorpicker"
],
remove the fullpage plugin from script
This might be simpler:
b = "<body>";
be = "</body>";
t = tinyMCE.activeEditor.getContent();
t = t.substring((t.indexOf(b) + b.length), (t.indexOf(be)-1)) //need substring() (including comment b/c can't make edit under 6 chars)
The "t" value can be then actively placed in the "textarea" value (not setContent()) of the tinymce editor, before sending.
Hope that helps..
