How to access frame (not iframe) contents from jQuery

Question

I have 2 frames in one page like this (home.html)

    $(document).ready(function(){
     $("#Button1").click(function(){
      $(parent.rightFrame.document).contents().find(‘#TextBox1’).val(‘Hello from left frame!’);
     });
    });

But I used :

    $.post("content_right.php",{id:id},function(data)
     $(parent.frames["content_right"].document.body).html(data) ;
    });
