Slick
Slick is a standalone selector engine that is totally slick. Slick is split in 2 components: the Finder and the Parser. The Finder's job is to find nodes on a webpage, the Parser's job is to create a javascript object representation of any css selector.
Slick allows you to:
- Create your own custom pseudo-classes
- Use the Parser by itself.
- Find nodes in XML documents.
The Finder
Find nodes in the DOM
search context for selector
Search this context for any nodes that match this selector.
Expects:
- selector: String or SelectorObject
- (optional) context: document or node or array of documents or nodes
- (optional) append: Array or Object with a push method
Returns: append argument or Array of 0 or more nodes
slick.search("#foo > bar.baz") → [<bar>, <bar>, <bar>]
slick.search("li > a", [<ol>, <ul>]) → [<a>, <a>, <a>]
slick.search("#foo > bar.baz", document, []) → [<bar>, <bar>, <bar>]
find first in context with selector or null
Find the first node in document that matches selector or null if none are found.
Expects:
- selector: String or SelectorObject
- (optional) context: document or node or array of documents or nodes
Returns: Element or null
slick.find("#foo > bar.baz") → <bar>
slick.find("#does-not-exist", node) → null
node matches selector?
Does this node match this selector?
Expects:
- node
- node, String or SelectorObject
Returns: true or false
slick.matches(<div class=rocks>, "div.rocks") → true
slick.matches(<div class=lame>, "div.rocks") → false
slick.matches(<div class=lame>, <div class=rocks>) → false
context contains node?
Does this context contain this node? Is the context a parent of this node?
Expects:
- context: document or node
- node: node
Returns: true or false
slick.contains(<ul>, <li>) → true
slick.contains(<body>, <html>) → false
The Parser
Parse a CSS selector string into a JavaScript object
parse selector into object
Parse a CSS Selector String into a Selector Object.
Expects: String
Returns: SelectorObject
slick.parse("#foo > bar.baz") → SelectorObject
format
#foo > bar.baz
[[
{ "combinator":" ", "tag":"*", "id":"foo" },
{ "combinator":">", "tag":"bar", "classList": ["baz"], "classes": [{"value":"baz", "match": RegExp }]}
]]
h1, h2, ul > li, .things
[
[{ "combinator":" ", "tag": "h1" }],
[{ "combinator":" ", "tag": "h2" }],
[{ "combinator":" ", "tag": "ul" }, { "combinator": ">", "tag": "li" }],
[{ "combinator":" ", "tag": "*", "classList": ["things"], "classes": [{"value": "things", "match": RegExp }] }]
