Attaching script file to web site

Question

I have next question: can I in any way attach my script file to a web site opened in my web browser? This script should be executed only in my machine and should emulate events like onclick ,onmouseover, etc. I found that I can emulate that events in this way:

var element = document.getElementById('element_id');
var o = document.createEvent('MouseEvents');
o.initMouseEvent( 'click', true, true, window, 1, 12, 345, 7, 220, false, false, true, false, 0, null );
element.dispatchEvent(o);

But I don't understand how I can implement this code in concrete my situation? Where should I locate this code? How do I attach it the site? How can I generate browser's events for this site? And can I do it?

Have a look at userscripts and bookmarks with `javascript:` urls — Bergi, Oct 02 '12 at 15:58

You can bookmark the script in your browser and then click the bookmark to run it on the page you are currently on.

Load external JS from bookmarklet?
