@BrockA : could we please get this under a BSD or Apache 2.0, or some other compatible license? We'd like to include it in https://github.com/palantir/stash-disapproval-plugin which is apache 2.0. |

Something's wrong with current Firefox, the script just stops on targetNodes.each(). Still works on SeaMonkey or older Firefox, so it's not just me or the page I'm working with, or is it?
What I did was:
- targetNodes.each ( function () {
- var jThis = $(this);
+ for (var i = 0; i < targetNodes.length; i++) {
+ var jThis = $(targetNodes[i]);
And looks like it works, but I'm not sure if I'm not making some type-casting crime or whatever ;)

It fails to work when other javascript framework use $() as alias. So it's better to use jQuery() explicitly.
You can get update from my fork

Hey Brock. Thanks for your help over on StackOverflow!
I'm looking to post my greasemonkey script on GreasyFork and it @includes waitForKeyElements. However, GreasyFork doesn't allow includes of GitHub scripts by default and someone else is hosting a version of your script on GreasyFork.
GreasyFork has Github sync functionality.
A GitHub webhook connected with Greasy Fork makes it so any push to your GitHub repository automatically updates your scripts on Greasy Fork in a matter of minutes.
I'd love to @include your script instead of a copy. If you aren't interested in creating a GreasyFork account let me know and I'll use the already posted script. Otherwise, point me to the GreasyFork version.
Best!
Jeremy

@GollyJer, Interesting, there appear to be at least 4 copies of waitForKeyElements on Greasy Fork:
3 out of 4 of them even credit me; I can die in peace! :D
Anywho, I've no interest in creating a Greasy Fork account at this time. Use whichever version/method that works best for you.

Seems the unacredited version is mine, fixed now, Cheers :)
@GollyJer You could also import this script as a resource, like this :
// @resource waitForKeyElements https://gist.githubusercontent.com/BrockA/2625891/raw/9c97aa67ff9c5d56be34a55ad6c18a314e5eb548/waitForKeyElements.js
then read it with GM_getResourceText("waitForKeyElements ") and inject it on page or eval it in script.

@BrockA - Apparently github is delivering notifications 11 months delayed? wtf... Anyways, many thanks for chiming in! I might still like to use it but I don't maintain disapproval plugin much these days, so not sure if I will ever get to it. Thanks for contributing to the hive mind just the same! =D

@panayot-zhi - Even better yet, run the address through Git.io to get a shortened URL.
// @require https://git.io/vMmuf
Then use function normally.

Not sure if this has already been accomplished, but I couldn't find an example of this without the need for JQuery. I forked this and removed reliance on JQuery, though I had to hobble it by disabling the iframe search. Might help some though, and it works for my project. Thanks for your work @BrockA

@mjblay What a crazy coincidence. I have been re-writing it as well within this past week to no longer rely on jQuery, and I also ended up removing the iframe feature until I had more time to re-write that part in vanillajs. I had published a gist a couple of days ago, but I removed it after encountering a few bugs. I checked out your Gist/Github account and couldn't find the fork. Are you planning on publishing it on Github?
