How to make it so that when you go to a website page: http://noname.com/sendmessage.php
the text (*Hello) was automatically inserted into the message window, and after that the button was pressed: "submit"

I would be grateful for the sample script.

// ==UserScript==
// @name New Userscript
// @namespace http://tampermonkey.net/
// @version 0.1
// @description try to take over the world!
// @author You
// @match http://noname.com/sendmessage.php*
// @icon data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==
// @run-at document-end
// @grant none
// ==/UserScript==

(function() {
'use strict';

document.querySelector('textarea').value = 'Hello'; //Add the text to the text box

document.querySelector('input.button').click(); //Click on the submit button

})();
