12 * Optional (non-Sizzle) selector module for custom builds.
|
|
|
13 *
|
|
|
14 * Note that this DOES NOT SUPPORT many documented jQuery
|
|
|
15 * features in exchange for its smaller size:
|
|
|
16 *
|
|
|
17 * Attribute not equal selector
|
|
|
18 * Positional selectors (:first; :eq(n); :odd; etc.)
|
|
|
19 * Type selectors (:input; :checkbox; :button; etc.)
|
|
|
20 * State-based selectors (:animated; :visible; :hidden; etc.)
|
|
|
21 * :has(selector)
|
|
|
22 * :not(complex selector)
|
|
|
23 * custom selectors via Sizzle extensions
|
|
|
24 * Leading combinators (e.g., $collection.find("> *"))
|
|
|
25 * Reliable functionality on XML fragments
|
|
|
26 * Requiring all parts of a selector to match elements under context
|
|
|
27 * (e.g., $div.find("div > *") now matches children of $div)
|
|
|
28 * Matching against non-elements
|
|
|
29 * Reliable sorting of disconnected nodes
|
|
|
30 * querySelectorAll bug fixes (e.g., unreliable :focus on WebKit)
|
|
|
31 *
|
|
|
32 * If any of these are unacceptable tradeoffs, either use Sizzle or
|
|
|
33 * customize this stub for the project's specific needs.
