select-dom v9.0.0

select-dom

Lightweight querySelector/All wrapper that outputs an Array

Version 7+ only supports browsers with iterable NodeLists. If you need IE support, stick to select-dom@6 or lower.

Install

npm install select-dom

// This module is only offered as a ES Module
import {$, $$, lastElement, elementExists} from 'select-dom';

API

Note: if a falsy value is passed as baseElement, you'll always get an empty result (bd578b9)

$(selector[, baseElement = document])

Maps to baseElement.querySelector(selector), except it returns undefined if it's not found

$('.foo a[href=bar]');
// => <Element>

$('.foo a[href=bar]', baseElement);
// => <Element>

$('.non-existent', baseElement);
// => undefined

lastElement(selector[, baseElement = document])

Like $(), except that it returns the last matching item on the page instead of the first one.

elementExists(selector[, baseElement = document])

Tests the existence of one or more elements matching the selector. It's like $(), except it returns a boolean.

elementExists('.foo a[href=bar]');
// => true/false

elementExists('.foo a[href=bar]', baseElement);
// => true/false

$$(selector[, baseElements = document])

Maps to baseElements.querySelectorAll(selector) plus:

• it always returns an array
• baseElements can be a list of elements to query

$$('.foo');
// => [<Element>, <Element>, <Element>]

$$('.foo', baseElement);
// => [<Element>, <Element>, <Element>]

$$('.foo', [baseElement1, baseElement2]);
// => [<Element>, <Element>, <Element>]
// This is similar to jQuery([baseElement1, baseElement2]).find('.foo')
