Useful User JavaScripts for Opera

Tuesday, 10. March 2009, 09:37:30

, , , , , , , , , , , , ,

User JavaScript is a powerful tool and it can be used for many purposes, including:

  • Fixing broken scripts on Web pages. Opera uses browser.js to automatically fix incompatible Web pages, out of date scripts, and pages that inadvertently block Opera.
  • Enhancing Web pages by changing or adding your own content to the page.

Installing/Uninstalling User JavaScripts

If you don't have UserJS directory, create a directory with name userjs (preferably inside profile directory) and enter path to it in Tools > Preferences... > Advanced > Content > JavaScript Options... > User JavaScript files

Path to Opera User JavaScript directory
Path to User JavaScript files

  • To install, place User JavaScript file (*.js or *.user.js) inside User JavaScript directory.
  • To uninstall, remove corresponding User JavaScript file from User JavaScript directory.
  • To disable, change corresponding User JavaScript file extension from *.js to *.js.x
You can also use UserJS Manager for Opera to perform above actions.

I hoped, that Clean URI will allow me to click links redirected through blocked (in urlfilter) services, but it doesnt work, e.g.:
http://gazeta.hit.gemius.pl/hitredir/id=bVA6PwbWy7tIs_pJh5iLjfWoLSnFeKci5A0Cn.L6lp..H7/url=http://www.sport.pl/pilka/1,65050,6362363,Zakaz_za_wulgarne_okrzyki.html
Any chance to make it work?

Tamil 10. March 2009, 14:13

@ZAHEK, Thanks.

@Jurgi, Post in User JavaScript forum.

PolOpera 10. March 2009, 14:48

Thanks!!
Good job Tamil

albuemil 10. March 2009, 14:58

Great job like always :smile:

I would also recommend MultiPopup (http://www.hesido.com/web.php?page=multipopup ),i even managed to combine Multipopup with LinkAlert for a "complete" popup system :wink:

Anthony A 10. March 2009, 17:58

Thanks for these. Image Thumb is great I have used it many times since putting it in today.

Cooliris Alike would be very nice if I could make the preview bigger. The biggest size is too small to be useful and the smaller sizes are totally useless. I would like the current large size to be the smallest and than go bigger from there. What do I need to change in the code to do this?

Tamil 10. March 2009, 22:37

Change the height in following lines.
case '650px':
bar.style.height='450px'
break
case '450px':
bar.style.height='550px'
break
case '550px':
bar.style.height='650px'
toolbar.innerHTML = " <iframe src=\"about:blank\" id=\"cooliris\" width=\"400\" height=\"650\" style=\"max-height:95%;margin-top:10px\" onload=\"this.contentDocument.postMessage('cooliris')\"></iframe>";
var x=e.target.getAttribute('href');x=x?x:e.target.parentNode.getAttribute('href');var y=e.ctrlKey;if(y){time=window.setTimeout(function(){if (document.getElementById("Previewbar").style.height != "650px"){document.getElementById("Previewbar").style.height = "650px";document.getElementById("Previewbar").style.padding = "10px";document.getElementById("Previewbar").style.border = "1px solid black";}document.getElementById("cooliris").setAttribute("src", x);},1000)}

papasmurfrock 10. March 2009, 23:31

i can't seem to get the cooliris one to work. i am using a power book g4 with leopard operating system. i press ctrl while hovering over links but nothing happens.

am i doing something wrong?

Tamil 10. March 2009, 23:40

It will take little time to show.

papasmurfrock 10. March 2009, 23:50

thanks for the reply but it just doesn't seem to be working for me. it can't be the folder because some of the other ones are working...just not the one i wanted the most.

i am using an apple laptop, is there a different key i shoud hold rather than ctrl when hovering?

Tamil 10. March 2009, 23:54

Sorry, I don't know.

Nerak 11. March 2009, 00:04

w000000t! Thanks, Tamil...excellent info! :yes:

Anthony A 11. March 2009, 00:20

OK thanks that fixed the height but how do I make the preview wider Tamil?

Tamil 11. March 2009, 00:28

Change the value of width in the following line. 
toolbar.innerHTML = " <iframe src=\"about:blank\" id=\"cooliris\" width=\"400\" height=\"650\" style=\"max-height:95%;margin-top:10px\" onload=\"this.contentDocument.postMessage('cooliris')\"></iframe>";

Anthony A 11. March 2009, 00:42

Thanks that worked.

BabyJay99 15. March 2009, 01:27

Wow. Tamil do you have post or tutorial on designing blog page? As you know my css making friends bonkers. I cant amend it while using mobile as there are maximum sentences in the screen :faint:

Tamil 15. March 2009, 01:37

BabyJay99 15. March 2009, 02:02

Thanks Tamil. Namaste :wink:

andreabianco 16. March 2009, 08:55

That was very useful and interesting, thanks Tamil! :smile:

ellinidata 18. March 2009, 01:29

Tamil,
I am glad I came back!
I needed to know how "Change the value of width in the following line"

Tamil 18. March 2009, 01:36

Change the value of 400 to required width. 
width=\"400\"

Papasmurfrock

Cooliris alike works fine for me on both Mac and Windows. On Mac use the "Command" key. It seems to take a little longer for the preview to show on the Mac but it works.

Anything wild I can do on operamini?
I saw the type in 'config:' power user hidden menu via address bar. It helped browsing.
On a 250kb+ page full of images, om4 fails to load all the images, where om3 split the page up and shows it all. Would be nice to have a work around menu to cure that.

LamboMan 26. May 2009, 18:39

Hello Tamil! I have a small problem, every time i load a userscript onto any page(your's or any others) it seems to block the browser.js file from rendering some pages correctly. But as soon as i turn off User JS for that web page, it gets activated again. I've even tried to put the browser.js file into my 'userjs' directory but it just won't work along with any of the userscripts i use!

So is there any way to make browser.js work when i have activated User JS?? Please help. :frown:

Tamil 27. May 2009, 05:18

I think one of your UserJS is interfering with browser.js.

LamboMan 27. May 2009, 11:24

Well, i have only been using those javascripts that you have provided on this page till now and only recently i started using another one. But even when i use only your's the browser.js does not work on pages.
You tell me, does browser.js work for you when you have activated user js? And if yes, then what is the configuration of your userjs directory? I mean have you put browser.js in it and what value do you use in "Browser JavaScript" under 'User Prefs' in opera:config ??
