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 }] }]
]
