thanks a lot!

If you're using Ajax, why not just send the POST yourself via an XMLHTTPRequest? That way the response comes right back to your script, without a page reload, and you can simply check the HTTP status and ignore the body.

On the other hand, I think that, from human interface design principles, loading the updated page with the new comment is a good thing, since it shows the new state of the page. Otherwise the user is left looking at an obsolete page that doesn't incorporate her new comment.

Ideally your script could still bypass the reload by splicing the comment into the page's DOM after the POST succeeds, but I am pretty sure that would require more knowledge of the structure of the HTML than is available, since the journal style can structure the tags pretty much any way it wants.

That is what I do.

«That way the response comes right back to your script»
I just want that responce be small and come quickly — improving user experience and saving his traffic.

And I do indicate that comment was sent in very obvious way.

I've got a bug - your ctrl+enter scheme doesn't work on OS X (not with ctrl+enter, apple+enter, or option+enter). Why not at least have a button or something?

I do not own a Mac. I did what I could — allowed both Alt+Enter and ctrl+enter. people say it works. How can those modifiers be checked with Javascript?

Можно каждый раз подставлять имя польз. и пассворд с пометочной "Лог ин".
В таком случае не будут показываться коменты.

Щасти.

Так скрипт ведь никак не может знать пароль и логин. Увы, не вариант.
