get-elements-array

Array of elements from selector, Array-like objects and single elements.

The purpose of this module is to simplify the interpretation of an "elements" parameter in your own functions/modules, kinda like jQuery does.

Usage

getElements() always returns a plain Array of elements with many types of input:

// a selector string:
elementsArray = getElements('.article img');
// => [<img>, <img>, <img>]

// a single DOM element:
elementsArray = getElements(document.body);
// => [document.body]

// a collection of elements:
elementsArray = getElements(document.body.children);
// => [<h1>, <p>, ...]

// an array of elements:
elementsArray = getElements([document.body, document.head]);
// => [document.body, document.head]

// an empty collection or null parameter:
elementsArray = getElements(undefined);
// => []

// `document` or `window:
elementsArray = getElements(document);
// => [document]

Note: it does not verify that the resulting array contains only elements. If needed, you can use a filter on the now-easy-to-use array:

const getElements = require('get-elements-array');
const isElement = require('lodash.iselement');

const elements = getElements([1, document.body]).filter(isElement);
// => [document.body]
