My OperaUser JavaScript in Opera 8 final
Wednesday, April 20, 2005 10:34:02 AM
Opera 8 final introduces one new limitation and several enhancements for the User JavaScript functionality.
The limitation first: because we are worried about potential spyware abuse, User JavaScripts will not run on pages that are encrypted. This is a big and very annoying limitation, and we're thinking hard about what we can do about it.
Now the enhancements: you can tell Opera to load all files in a folder as User JavaScripts, Opera has a GreaseMonkey-compatible mode to take full advantage of GreaseMonkey scripts with minimal or no editing, and there are new functions that simplify fixing pages: window.opera.defineMagicVariable and window.opera.defineMagicFunction lets you set persistent variables and functions that the page can not overwrite.

and the brand new tutorial on

which has several demo scripts and covers all the new and old features.

// ==UserScript==
// @include http://wp.pl/*
// ==/UserScript==
alert('test');
It should load alert window during loading page wp.pl. but it doesn't work at all. I'm a bit confused. What's wrong?

// ==UserScript==
// @include http://www.7thguard.net*
// @include http://7thguard.net*
// ==/UserScript==
alert('bla');
for http://7thguard.net works.
for http://www.7thguard.net doesn't work.
The problem is described in the thread: http://my.opera.com/forums/showthread.php?s=&threadid=87827
And I've got one more question concerning the thread: http://my.opera.com/forums/showthread.php?s=&threadid=88943 Why the entry: Always Load User JavaScript=1 doesn't work?

I have written the following script that should work for a number of sites:
// ==UserScript==
// @include http://www.leidschdagblad.nl/*
// @include http://www.limburgsdagblad.nl/*
// @include http://www.telegraafholding.nl/*
// @include http://www.hdcmedia.nl/*
// @include http://www.limburgadverteren.nl/*
// @include http://www.nhd.nl/*
// @include http://www.gooieneemlander.nl/*
// @include http://www.haarlemsdagblad.nl/*
// @include http://www.ijmuidercourant.nl/*
// @include http://www.dvhn.nl/*
// @include http://www.vakantierecreatie.nl/*
// @include http://www.almerevandaag.nl/*
// ==/UserScript==
window.opera.defineMagicVariable(
'bSupportedBrowser',
function(){return true;},
null
);
When I try it, it doesn't work. If I remove all @include lines except the first, I can open <http://www.leidschdagblad.nl> without any problems. Am I doing something wrong?
