Java/Greasemonkey problem

[noname219]

So, I've installed a Greasemonkey script on a website and I want to give it some modifications.
The website is rateyourmusic.com and the script in question can be downloaded here : http://userscripts.org/scripts/show/151158.
Basically, the script automatically calculates the average rating of an artist page.

I was able to modify it a little bit (adding more decimals and having it to calculate the bootlegs/videos and tribute releases) but I also want to have the total number of releases of the artist.

Last picture gives you an idea of what I mean :



Oh yeah, and there's some credit saved for anybody that helps me. :)

Bump, who here wants 50k credits ?

[qqwref]

Can't you just make a global counter (e.g. albumCnt) and add one for each album you find (e.g. albumCnt++; before ratingCtr = ratingCtr + ratings;)?

Me! But I don't know Java/greasemonkey well...

[noname219]

The thing is, I know nothing at all about Java. I was able to modify the script by trial and error and that's about it.
I tried messing a bit with the code again but so far, I'm stuck.

This doesn't even look like Java. More like JavaScript (which is a totally different thing btw).

lol

Thanks for helping btw.

[dAnceguy117]

qqwref is correct. Java isn't actually what you're asking for help with. you're working with JavaScript.


I'll take a really quick stab at it. no guarantees, but hopefully I can point you in the right direction. I'll check back in tomorrow.

Gives me no number of releases, just an "undefined" value.

You can also add this at rows 99-101 (so it will calculate bootlegs, videos and tributes) :

parseAlbum('album_disc_b');
parseAlbum('album_disc_d');
parseAlbum('album_disc_t');

Copypasting everything gives me 3 albums for Broken Bells. (should be 6 albums instead)
(http://rateyourmusic.com/artist/broken_bells_f1)

[dAnceguy117]

interesting. let's try fudging the numbers, lmfao. these should be correct for Broken Bells but probably won't work for other artists.

replace the line that's spaced out near the top with one of these at a time.

// get number of albums. danceguy sucks at coding
        numAlbums = albums.length + 1;

// get number of albums. danceguy sucks at coding
        numAlbums = (albums.length - 2) * 2;

hmmm. now that I look at the link in your above post, I think this problem could be pretty tricky. which six releases are the ones you want included?

Those two lines gives me 6 albums for each of them, but they don't make sense with other artists.

It's actually 7 albums (with the bootleg) :
Broken Bells (album)
Meyrin Fields EP
The High Road
The Ghost Inside
October
Meyrin Fields
The MySpace Transmissions
(no appearances, but they shouldn't be included by default)

You should add this in the code :

parseAlbum('album_disc_b');
parseAlbum('album_disc_d');
parseAlbum('album_disc_t');

(should add the cumulative rating of other sections I mentioned above - post#9)

[dAnceguy117]

I'm an idiot

give this one a shot. extra parseAlbum lines included, but I removed
parseAlbum('album_disc_c');
because I don't think you want to include the compilations. right?

edit:

the magic number here should be 8. excluding anything with "Appears on" would be the finishing touch.

if it gives you 4 albums for Broken Bells, let me know. that's an easy fix.

[noname219]

Gives me a NaN...

And compilations will get included as well, but if you remove it, you'll affect the average rating at the same time.

[dAnceguy117]

oops I grabbed the wrong version lmfao. compilations put back in, so you should get 11.

Awww yeah. :) Gives me the exact number on every page.

Only thing left is to remove the appearances and everything will be perfect.

sweeeet hahah. I'll take a crack at the final changes over the weekend.

unless someone else wants to! QQ, I KNOW YOU'RE WATCHING

bump, sorry again for the holdup. can't believe it's been a month, what the...

noname, where do you put this script/run it from? knocking this out would probably be 10x faster if I could test it myself

[noname219]

Not sure if I understand your question.
This is the website : http://rateyourmusic.com/
The script acts everytime you load an artist page. (supposing you already have downloaded the Greasemonkey extension for Firefox/Chrome)
