scan

standalone querySelectorAll selector engine with jQuery-like interface

Basic usage

var scan = require('scan')
scan('.example').find('a').not('[href^="#"]')

API (0.9)

• scan() instances are array-like and inherit from scan.prototype and Array.prototype
• scan() methods chain intuitively or are callable via scan.prototype[method].call(array)
• Methods are generally compatible with jQuery methods of the same name

scan(query, context?)

• scan(selector) → elements that match selector
• scan(selector, node|nodes) → elements that match selector from node or any nodes
• scan(node|nodes) → nodes wrapped in scan instance

.find(needle)

• scan(query).find(selector) → descendants that match selector
• scan(query).find(element|elements) → elements that descend from query
• scan(stack).find(fn, scope?) → the first value to pass fn.call(scope, value, i, stack)

.filter(needle)

• scan(query).filter(nodes, selector) → stack filtered by selector
• scan(query).filter(fn) → stack filtered by fn.call(element, i)
• scan(query).filter(element|elements) → stack filtered by one or more elements
• scan(array).filter(values) → the intersection of 2 arrays

.not(needle)

• scan(query).filter(selector) → nodes filtered against selector
• scan(query).not(fn) → stack filtered against fn.call(element, i)
• scan(query).not(element|elements)→ stack filtered against one or more elements
• scan(array).not(values) → the difference of 2 arrays

#find(needle)

• scan.find(selector, context?) → array of elements that match selector
• scan.find(stack, fn, scope?) → the first value to pass fn.call(scope, value, i, stack)

#matches(element, selector)

• scan.matches(element, selector) → true if element matches selector

#contains(haystack, needle)

• scan.contains(node, element) → true if node contains element
• scan.contains(stack, item, start=0) → true if stack contains item
• scan.contains(str, substr, start=0) → true if str contains substr
