I’m having the same problem
Also first time using userscripts, don’t know very much about coding at all but I will post a screenshot of the javascript console errors if that helps
It seems you don’t have [WaniKani Open Framework] installed, or it’s not in the #1 position in your script list.
You, my friend, are a hero. Thanks!
Just to confirm that I do and it’s in the #1 slot.
Getting this same error. Was not getting this earlier this AM.
I am getting the undefined error in Firefox 112.0.2 (64-bit)
Furthermore, if I do it for a reading it tries to write undefined in kana as such:
うんでふぃねd
I too am experiencing the undefined and うんでふぃねd error when pressing F specifically using Brave
Yesterday’s change to Double-Check was to make it so mobile users’ keyboard wouldn’t close between every review. I did that by keeping the input box focused even after you’ve answered the review.
Unfortunately, that means hotkey events are no longer going where they’re supposed to go, and it sometimes does weird thing to the input box. I started looking into it last night, but I had to stop since I’m picking up my former exchange student from the airport today (she’s visiting from Osaka).
I’ll resume trying to find a way for both things to work together, but for now I think most users can drop back to [v3.1.0], and I’ll get a fix when I have some time tonight.
Thank you for working hard and have fun with your friend!
Unsure if this is related to that - when trying to add a note to an item after answering and expanding the details, if you press backspace to try and delete a character it undoes that item. I’m pretty sure this didn’t used to happen but I could be wrong about that. It would preferably just contain the backspace to the textbox if it’s selected!
I’m also having this issue.
I’ve posted a new version [v3.1.7]:
- Re-added fix for mobile keyboard focus, without breaking backspace.
- Added support for changes to the WK answer checker code (currently on preview, scheduled to hit production tomorrow).
- Added support for upcoming Kana Vocabulary (no good way to fully test, but it’s a start).
Hey, I’m having this odd thing happen where I hit enter and I don’t get the color highlighting indicating whether I got it right or not. I think it’s the Double Check script, it’s one of 4 I have installed (other three are Niai Similar Kanji, Show Context Sentence, and Open Framework). Color highlighting on right/wrong answers returns when I disable the Double Check script, so I’m assuming it’s this one. This is a screenshot of what it looks like when I enter a wrong answer: everything still works, it’s only the color that’s missing.
I haven’t messed with any settings, but if I’m supposed to, I can definitely do that, I’m just very new to userscripts haha. Thanks so much for developing this awesome script and sharing it!
Edit: Basic reporting misstep, I forgot to add browser, I’m using Firefox on Windows =)
Edit 2: Updating fixed it, my bad I forgot to even check, thanks to @marciska for the reminder haha
The Answer Checker during review session was updated (see here). WKOF and DoubleCheck-script already received an update ahead, so just click on “fetch updates” ![]()
Also mentioned here:
This fixed it! I thought I saw something on TamperMonkey that said it would update automatically so it didn’t even occur to me to look, though I should have known better than to post without checking for updates haha. Appreciate you =)
I’m having a minor bug issue. Not entirely sure what the root cause is, but it seems that after changing some answers to correct they don’t get removed from the queue correctly, so I wind up in a state where I have to answer them multiple times and then have negative questions remaining according to the progress bar.
Anyone else seen something like it?
I’ve had some issues recently with Tampermonkey not properly updating, I had to manually reinstall to get the correct version, not really sure why as versioning seemed to be correct.
On a side note, this made me appreciate the script even more, I was using it only for the lighting mode and mistake delay, but I JUST realized that there is the “careless mistakes” section. I honestly thought those warnings started popping up due to a base WK update - they honestly should be.
Are you using the newest version (v3.1.7), and are you using any other scripts?
I found the problem you are referring to, and just posted a new version [v3.1.8].
I apologize for any answers that didn’t get corrected properly ![]()
