Selector lite –

DEPRECATED! It is merged into dom-lite. Use require('dom-lite/selector')

A small pure-JavaScript CSS selector engine.

• no library dependencies
• CSS 3 Selector support
• only 2KB minified and 1KB gzipped

Examples

var selector = require("selector-lite")

// Can be used to implement browser built-in functions.

function getElementById(id) {
    return selector.find(this, "#" + id, true)
}
function getElementsByTagName(tag) {
    return selector.find(this, tag)
}
function getElementsByClassName(sel) {
    return selector.find(this, "." + sel.replace(/\s+/g, "."))
}
function querySelector(sel) {
    return selector.find(this, sel, true)
}
function querySelectorAll(sel) {
    return selector.find(this, sel)
}

Methods

• selector.find(node, selector, returnFirstMatch) - Find matching elements like querySelector.
• selector.matches(node, selector) - Returns a Boolean indicating whether or not the element would be selected by the specified selector string.
• selector.closest(selector) - Returns the Element, descendant of this element (or this element itself), that is the closest ancestor of the elements selected by the selectors given in parameter.
• selector.next(selector) - Retrieves the next sibling that matches selector.
• selector.prev(selector) - Retrieves the preceding sibling that matches selector.

Custom selectors

Custom selector can be added to selector.selectorMap, where method shortcuts are available (m->matches, c->closest, n->next, p->prev).

• _ - node.
• v - part between () in :nth-child(2n+1).
• a and b can be used as temp variables.

// Add `:input` selector
selector.selectorMap.input = "_.tagName=='INPUT'"

// Add `:val()` selector
selector.selectorMap.val = "_.value==v"
