The way I understand it, function document.getElementsByTagName() returns an array of elements. In this case, elements of the array are tables, hence the attribute 'table'. The for-loop goes through each element in the array, as there will always be more than one table.
The document.get... grabs a list of elements, and then to weed out those elements, I use a for-loop.So, basically, where devin is using xpath, I'm using document.get, and where he's using document.evaluate, I'm using a for-loop.

The reason I'm saying people could change numbers is because I think they might prefer a different maximum length to the bars compared the way they are set up in the code. So, if you change numbers 50 and 100 to 500, that would mean maximum bar length you get to see is 100kg. Having a bigger backpack won't affect the length of the bar, it will just stay a constant.
One other thing I could perhaps add, is the @include lines should be replaced to look like this.
// @include http://improbableisland.com/inventory.php?items_context=*
// @include http://www.improbableisland.com/inventory.php?items_context=*
This will make sure the script only gets executed when looking the inventory. (a bit of testing is advised, but I think this should work)

If you can do something that alters the code on the fly, and if you can store those parameters as well, that would be awesome. Been trying to find a way to do that for a while now. Didn't even think userscripts allowed you to do that. From what I understand, you can only change temporary values, and even that, only for each window separately. But as I say, I don't really know much on userscripts. I'd love to see it, if you get it working.

Ah, I see it now. Okay then, here's the new code:

Hmm. Apparently Opera doesn't do any GM_ functions by default.
There's an emulator for that though.

Stolen from this site:
(right-click, save in your Opera userscript folder)
http://www.howtocreate.co.uk/operaStuff/userjs/aagmfunctions.js

With that, most of scripts should work pretty sweet. There are some exceptions though.
The good part of it is that your values won't stay in your about:config forever The bad part, when you clear cookies, values get deleted as well.

Then about the @include:
// @include http://improbableisland.com/inventory.php?items_*
// @include http://www.improbableisland.com/inventory.php?items_*

This should make sure to trigger the script only while looking the inventory, without exploding again when for instance transferring, discarding or using an item.

And now back to commenting the script.

When you're defining variables, you have:
var new_size = GM_getValue("Length", 250);
var cutoff = GM_getValue("Length", 250);

One of them should be "cutoff"

Then after that, add an if-statement Like so:

As per this thread here, I have a request.

I don't suppose a Greasemonkey script could hide the "Jungle" link on all the pages in which it appears, could it? It would be useful to temporarily install when you really want to avoid the Jungles but can't beat your habit of clicking it.

Edit: Or at least put it in flashing DON'T CLICK THIS colors. That'd help, too.

Hahaha NEVERMIND

See, it's funny, because... eh... heeeeeeeeeeeh.

Yes... right.

Okay, sorry for the long response. Here's the updated code, that'll only execute at inventory, and only for inventory bars.

I love these scripts. They make II so much more user-friendly, and thank you all for writing them. But, as of today, I seem to have three XP bars. The third appears to be a copy of the second, filling at the same rate. Wut?

For some reason, none of the inventory limiter scripts posted actually work for me. 90% of the time, they just refuse to hook into the page, and it mystifies me.

Buddella:

Okay then. Lesse. Here's the thing. Chrome does support Greasemonkey scripts, yeah, but not Greasemonkey-specific functions, like GM_setValue(), which the script uses to allow it to make on-the-fly changes. At least, the version I messed with. If you can edit the code--you should be able to, tell it to open with notepad/wordpad--try changing code to this:

I installed the XP bar, the Quest tracker, and the inventory limiter. The XP bar works great! But the Quest tracker displayed "None", even though I doublechecked at the PSK and did have a quest. Then I abandoned that quest and now it displays the new one properly. (If there's any information that I should have recorded... sorry. Forgot. D: )

The inventory limiter won't install, period. That might just be my computer though.

Good to hear, Matthew. And if you want to change the cutoff size, you'll have to change it manually, by changing the values:

@ tahvock
In the links you post, bar limiter links to the same script as truancy bar

@ buddlea
One of your scripts is a copy. Might have happened if you simpy installed what tahvock posted.
If that is the case, remove that one from your userscripts, then select one of the bar limiters posted in this thread and save it as .user.js and open it with firefox.

@iriana
That's how the quest script works. It doesn't detect the quest you're currently on when you first install it. Should work fine after that.. And for bar limiter, see above.

@Matthew
Tried Opera yet?

Derp. *Facepalm* Well I feel like an idiot now. Here's the proper links.

Truancy Bar
Quest Tracker
Bar limiter
Mail Check

:'D Clearly I need to look at what I'm installing next time.

Thanks, bl0b and Tahvohck! Everything works beautifully now.

So I'm gonna put this out there before even thinking about starting, but who would be interested in a rail pass calculator? As in, it reads the cards you have, and tells you how many rail passes you could get?

There are plenty of stations strategically placed throughout the island where you can get the information. You'll only dumb us down with such a script.

I do have a different train-related idea. When you're traveling first class, you can request a stop and you have to enter coordinates. Can you make a list of favorites to input? I'd love to be able to travel to my own dwelling without that pesky stuff of remembering and entering coords, or landing exactly on Pleasantville or Squat Hole without all that hard work of walking for 1 or 2 squares.
