Rails spinoffs - Sep 2007 - 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. http://us2.php.net/manual/en/function.addslashes.php

Cheers,
      Matt
