Getting selected options with querySelectorAll
I wonder if it’s possible in Javascript to get the currently selected options in a <select multiple> field using the Selctors API rather than a “stupid” iteration over all options. select.querySelectorAll(‘option[selected=”selected”]’) only returns the options that were marked as preselected in the original HTML, which is not what I’m looking for.

Javascript like $(document).ready() for “modern HTML5” browsers
This is most likely already a question somewhere, but I cannot find it, as EVERY single search turns up jQuery questions.

Find by key deep in a nested array
Let’s say I have an object: I want to find the one object where the id is 1. Is there a function for something like this?

Inject CSS stylesheet as string using Javascript
I’m developing a Chrome extension, and I’d like users to be able to add their own CSS styles to change the appearance of the extension’s pages (not web pages).
