Post an update(message) twitter

How can I post a message to twitter using only javascript (no serverside authentification).

For example I have a form with username, password, and a text field and a submit button.

I want to use it on the backend of a website.

I have read this, http://dev.twitter.com/doc/post/statuses/update but I do not know how to handle the authentification of the username.

(I know that开发者_运维百科 it involves many security risks doing it this way)

either use the javascript twitter api helper at http://sources.disruptive-innovations.com/twitterHelper/tags/latest/TwitterHelper.html

or the far easier way is to use the @anywhere api from twitter (http://dev.twitter.com/anywhere/begin)

Thanks @Nikolaus Gradwohl!

I made a little example for myself.
