},
success: function(data, textStatus){
if(data=="success")
statusdiv.html('<p class="ajax-success" >Thanks for your comment. We appreciate your response.</p>');
else
statusdiv.html('<p class="ajax-error" >Please wait a while before posting your next comment</p>');
commentform.find('textarea[name=comment]').val('');
}
});
return false;
 
});
});

}

It does not show that comment immediately.
