evalJSON problem

Hey there,
I have a FCKeditor(a WYSIWYG online html editor) and i want
to bring
it to a page by Ajax and JSON by a php request-catcher.
I have sth like this in my ajax request:

new Ajax.Request('myactions.php',
  {
    method:'get',
	parameters: {action:'bringeditor', id:<?php echo $uid;
?>},
    onSuccess: function(transport){
          var response = transport.responseText;
    	      var data = response.evalJSON();
	      $('maincontent').innerHTML=data.mytextarea;
	      eval(data.jsaction);*/
    },
    onFailure: function(){ alert('Something went wrong...')
}
  });

and in 'myactions.php' :
			$textarea= "<textarea id='MyTextarea'
name='MyTextarea'>
$txtareacontent</textarea>\n";
			header("Content-type: text/javascript");
			$jsaction= "var oFCKeditor = new
FCKeditor('MyTextarea');\n";
			$jsaction.=
"oFCKeditor.ReplaceTextarea();\n";
			echo "{mytextarea: $textarea, jsaction:
$jsaction}";

now the problem is that i dunno what user enters in the
editor, and
i've got problems handling characters that may conflict with
the JSON
request ( like "  n etc) what can i do ? i tried $H
... no use. thX

Hey there Parsa,

 I'd suggest just building the textarea in the page and
hiding until
the user needs it, lazy loading like that can be a big
headache as im
sure you already know.

To avoid complications with forward slashes you could use
the string
method, addslashes.

Cheers,
      Matt
