Edit to title and body field

Hello.

I wanna Ajax edit to node title and node body field.

I have tryed this and still worked.
but I think this is not smart. because 1. need module_hook 2.Can't use wsywig editer 3.html tag to urlencoding

/**
 * Implementation of hook_nodeapi()
 **/
function hook_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL) {
  switch($op) {
    case 'view':
          $node->content['jeditable_body']['#prefix'] = '<span id="node-'.$node->nid.'-body" class="jeditable-textarea">';
          $node->content['jeditable_body']['#value'] = strip_tags($node->content['body']['#value']);
          $node->content['jeditable_body']['#suffix'] = '</span>';
  }
}

This is very good module!
Thank you!
