ck_editor不加载实际数据

Question

Why doesn't the ck editor load the last change that I made in source mode? If I have disabled the ck_editor, then the textarea will show all the data. This is my code:

<textarea name="content" id="editor1" rows="10" cols="80">
   <?php print $selecteddata['content']; ?>
</textarea>

<script>
       // Replace the <textarea id="editor1"> with a CKEditor
       // instance, using default configuration.

       CKEDITOR.replace( 'content' ,{
          filebrowserBrowseUrl : './public/browse.php',
          filebrowserUploadUrl : '/uploader/index.php',
          uiColor : '#9AB8F3'
      });

</script>
