javascript question re user.js

Hi Jürgen,

I think you have to use 'BeforeExternalScript' to prevent
external scripts  
 from being executed. The script, that I use looks like
this:

// ==UserScript==
// name Prevent some ads (added by external javascripts)
// author graste[ät]gmail[d0t]com
// namespace http://userjs.org/
// description Disables the loading of external
javascripts that
//				contain "googlesyndication",
"targetpoint",
//				"smarttargetting",
"intellitxt" etc. in
//                      their 'src' attribute
// include *
// ==/UserScript==

// This script is granted to the public domain.

// remove ads that are inserted by external javascripts
window.opera.addEventListener(
	'BeforeExternalScript',
	function(ev){
		var src = ev.element.getAttribute('src');
		if(
src.match(/https?:\/\/([^\/]*\.)?(googlesyndication|targ
etpoint|smarttargetting|intellitxt|aspalliance)\.com\//i) 

) {
			ev.preventDefault();
		}
	}
	,false
);

I put the code above in a .js file and saved that file in my
userjs  
directory with some other user javascripts as well.

Perhaps it helps...

Regards,

Graste
