Two things:
1: When using SEAFs, you must use semicolons? at the end of functions and anything preceding the SEAF so it doesn't think you're trying to call some kind of weird function
So "}(function(){})()" is seen as "function(){}()()" with a function as an argument, thus "undefined is not a function" is thrown; it should become "};(function(){})();", notice the semicolons.
2: it's webkitRequestAnimationFrame()
Thanks? for the tips! Haha what a moment when the whole thing didn't work at the end. (if readers are wondering, SEAF = Self-Executing Anonymous Function)
Oh, yeah. I deleted that comment cause I remembered that last time I mentioned the redundancy of getElementById, there was? a huge argument.
Anyways, you're welcome for the tips :)
I just tried it out and the variable was? indeed defined, so no argument there ;)
You deserve? more views!
Thanks!? Please share. I think this style should replace high school CS courses.
Basically, I thought some js purist was going to? come along and start a long debate about why we should use getElementById even though it's redundant.
This seems to happen every single time I point out something of the like.
Anyways, I'm glad my tips helped :)
Yeah, I've been screwed by the "undefined/null is not a function" error countless times, haha.
How about the app-breaking 'unexpected token u' error that comes with making a tiny localStorage/JSON error. Then you have to manually delete the localStorage and carefully eyeball the error in? the code.
A weird part of those errors is that the very first line in the HTML source gets indiscriminately highlighted.
Fun times, eh?
