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