uSelector

A micro, super fast, scope limited, javascript selector engine to be used anywhere

uSelector (micro selector), is a node selector for HTML documents that uses css expressions to select nodes. It's based on Slick, the selector used on the Mootools javascript framework.

Supported selectors

  • tag
  • id
  • class
  • custom pseudo-classes

Unsupported selectors

  • combinators (ex: "div span", "div > span")
  • multiple expressions (expressions with comma, ex: "div, span")
  • attribute (ex: "a[title='title']")

Suported with the uSelectorPseudoClasses module

  • :empty
  • :first-child
  • :last-child
  • :only-child
  • :first-of-type
  • :last-of-type
  • :only-of-type
  • :disabled
  • :checked
  • :selected

note: To build with these pseudo-selectors included do make build all=true

How to use

$u('your-selector') -> returns an array of nodes that match the selector

Create your own pseudo-class

$u.pseudo['your-custom-pseudo'] = function(node){
    return boolean;
};

It should return true if the passed node fits the behavior of your pseudo. see the "src/uSelectorPseudoClasses.js"

Examples

<div>
    <span>text</span>
    <strong class="strong-class">strong-text</strong>
    <div id="id" class="div-class"></div>
</div>
  • $u('strong.strong-class') -> [<strong.strong-class>]
  • $u('span') -> [<span>]
  • $u('#id') -> [<div#id.div-class>]
  • $u('div#id') -> [<div#id.div-class>]
  • $u('div#id.div-class') -> [<div#id.div-class>]
  • $u('em') -> []
