sanitize-elements

Makes sure you've got dom elements, if dom elements are what you want

Accepts a dom node, a node list, a jQuery object, an array of dom nodes, etc. Will return dom elements as a plain array. Single dom elements can be wrapped in an array if optional wrap param is passed as true. If dom element(s) aren't passed in, returns false.

Install

npm install sanitize-elements

Usage

sanitize-elements is meant to be consumed in a CommonJS, Browserify environment (though you can also use a pre-bundled version, more below):

var sanitizeElements = require('sanitize-elements');

sanitizeElements(elements, wrap)
// elements: elements to sanitize
// wrap: wrap single dom elements in array, default false

Some simple (abstracted) examples:

sanitizeElements(document.querySelector('.element'))
// returns $element

sanitizeElements(document.querySelector('.element'), true)
// returns [$element]

sanitizeElements(document.querySelectorAll('.elements'))
// returns [$element, $element, ...]

sanitizeElements($('.elements'))
// returns [$element, $element, ...]

sanitizeElements(window)
// returns false

sanitizeElements('iWannaBeAnElement')
// returns false

In the context of a function:

var something = function($elements) {
	
	if ($elements = sanitizeElements($elements)) {
		// do something
	} else {
		console.warn('Pass in some elements please!')
		return
	}

}

Bundled Version

If you don't want to mess with a build process you can also include the pre-bundled version found in dist/sanitize-elements.bundled.js in your project which exposes sanitizeElements() globally.
