Installing User JavaScript

Before User JavaScript can run in Opera, you must enable the feature by pointing Opera to your User JavaScript directory

1. Create a directory for storing User JavaScript files, for instance C:\userjs\
2. Go to Tools -> Preferences -> Advanced -> Content -> JavaScript Options. Add the location of your newly created script directory to My JavaScript files.

Installing User JavaScript files
Scripts can be installed in one of the following ways:

1. If you want to review the script prior to installation, you can just visit the script, and select “Save As…” when you are viewing the script.
2. Mouse: By right-clicking the download link, and select “Save target as … “. Save the script to your previously created User JavaScript folder.
3. Keyboard: By focusing the download link, and pressing “Ctrl-Shift-S”. Save the script to your previously created User JavaScript folder.

Uninstalling User JavaScript files
Permanent uninstallation of User JavaScript files is done by deleting the script file from the folder containing your User JavaScript files.

If you want to disable a script file without permanently removing it, this is easiest achieved by changing the file suffix of the script file. Example: renaming myScript.js to myScript.js.xx will disable the script.

Also you can use UserJS Manager for installing and disabling UserJS.

For developers
http://userjs.org/help/tutorials/

Avoid a global variables and functions. Use anonymous function:

(function(){
  Yours code
})();

If you uses non english symbols in UserJS, encode it (\uXXXX) or save script in utf-8 without BOM (not works in Opera 9.2).

For getting info from other domain use cross-document-messaging. For compatibility with Opera 8-9 and Opera 9.5 use similar code:

if(window.postMessage){frame.contentWindow.postMessage(post)}else{frame.contentDocument.postMessage(post)}

Certain bugs
«window.getSelection()» - loses line feed. Try «document.getSelection()» or see quick-reply.js
«window.getSelection().containsNode()» - Always false.
«document.selection.type» - «None» even if selection exists. Opera 9.5 only.

«mousedown» - breaks drag-n-drop on page. Use «BeforeEvent.mousedown»

And good job with the FAQ Lex1.

Excellent FAQ.
Still, I'd suggest to add brief explanation next to each Site-specific UserJS above. Plus, add a link to the author's site with an updated explanation in English or any other language (to use with translator). Its scary to install a generic name script without knowing what it does.

brief explanation

OK.

add a link to the author's site

Direct links are given only for simple in the use scripts, and in such scripts usually exists of links to the site.

Nice list , but i have a question .

Good job Lex1.Thanks.

Is there any difference between to be worked this scripts under windows and linux?
Becouse some my colleagues said to me some userjs doesn't work with linux.But windows is OK.

Any reason why scripts wouldnt work - I have the copy clipboard script and google images script, and neither works. I have built a script dir in my profile and set it in preferences, and made sure to check the enable java script box, and set the option in opera6.ini to: Always Load User JavaScript=1 and yes i restarted opera several times.

After all that I also installed the userjs manager, it shows my scripts activated, but they do nothing.

This doesn't seem to be working in Opera 10 anymore. Example: http://trash.chregu.tv/xdom.html

I have a question: Why isn't UserJS allowed to make cross domain requests? Widgets are allowed to do so...!?

Hades32

document.addEventListener("message",function

Use window.addEventListener

Why isn't UserJS allowed to make cross domain requests?

Security. Afaik, userjs run in the context of page. GM-scripts is isolated. Widgets at all have no access to page.

Originally posted by Lex1:

Nope. You can allow them access to any page you want.

«Widgets at all have no access to page» in browser.

ahh, yes. That's sadly correct.

Same here.
But, I found here a post regarding the override.ini file.
I didn't delete anything, as the poster there suggests, but changed the relevant User JavaScript values from 0 to 1.
Seems to help, tho I'm not yet convinced everything is working as it should...

Simple localStorage для Opera 8.5-10.1. Windows only.

thanks again! great FAQ

+1 lo

For developers/fix creators.

From Opera 10.5 has been removed:
- document.addEventListener("load", ...) (just use window.addEventListener("load", ...) )
- document.selection
- element.text

Is (was) document.selection the same as window.getSelection()?

Yes, something like (window|document).getSelection, from IE-world.
document.selection also can to work with a textarea, what has no direct analogue. However, it is mainly essential for bookmarklets.

Allright, I think I have done something wrong because the downloaded script contained 0 characters, I don't know why. But now it's fixed and it works fine. Also Unite's UJS Manager is a great tool, it makes it so easy to download new scripts!

document.selection.createRange().text

Approximate analogue:

var getText=function(){var d=document,s=d.getSelection(),t=d.getElementsByTagName('textarea');if(!s)for(var i=0,e;e=t[i];i++){if(s=e.value.substring(e.selectionStart,e.selectionEnd))break}return s};

operaflag.js - analogue of flagfox extension. It will display, at the top-right of the page, the flag of the country from where the website is hosted.

Nice list of FAQ. Thank you.
