* Optional (non-Sizzle) selector module for custom builds.

7 |
*
|
|
|
8 |
* Note that this DOES NOT SUPPORT many documented jQuery
|
|
|
9 |
* features in exchange for its smaller size:
|
|
|
10 |
*
|
|
|
11 |
* Attribute not equal selector
|
|
|
12 |
* Positional selectors (:first; :eq(n); :odd; etc.)
|
|
|
13 |
* Type selectors (:input; :checkbox; :button; etc.)
|
|
|
14 |
* State-based selectors (:animated; :visible; :hidden; etc.)
|
|
|
15 |
* :has(selector)
|
|
|
16 |
* :not(complex selector)
|
|
|
17 |
* custom selectors via Sizzle extensions
|
|
|
18 |
* Leading combinators (e.g., $collection.find("> *"))
|
|
|
19 |
* Reliable functionality on XML fragments
|
|
|
20 |
* Requiring all parts of a selector to match elements under context
|
|
|
21 |
* (e.g., $div.find("div > *") now matches children of $div)
|
|
|
22 |
* Matching against non-elements
|
|
|
23 |
* Reliable sorting of disconnected nodes
|
|
|
24 |
* querySelectorAll bug fixes (e.g., unreliable :focus on WebKit)
|
|
|
25 |
*
|
|
|
26 |
* If any of these are unacceptable tradeoffs, either use Sizzle or
|
|
|
27 |
* customize this stub for the project's specific needs.
