I haven't had any problems in FF or Chrome, but IE9 chucks an error on this method. I thought I would be able to use it, due to it having been shown to be supported here:
http://www.quirksmode.org/dom/w3c_core.html
However, that appears to not be the case in practice. That being said, what can I use in its place?
EDIT: Here's the exact line it fails on:
var maximize_buttons = document.querySelectorAll(".maximize");
That is the first time I attempt to use querySelectorAll(). The browser version number is 9.0.8112.16421
EDIT (again): I've verified this error on two separate computers. However, there's one thing in common that they share - they're both running Windows 7 on VMware. Is that relevant?
Browser mode was IE9, but document mode was set to quirks by default. Changing it to Internet Explorer 9 standards fixed the problem, but if quirks is default, I still need to make it work for that.
