About
A tiny Node.js module for quickly selecting HTML elements.
Bundle it with browserify/webpack/etc.
Requires Node.js > 4.0.
Why
- Because using
jQueryjust to select elements is like using a flamethrower to light a birthday candle - Because
document.querySelector()is slow - Because
HTMLCollectionsare cool and all, but I usually want an actualArrayto iterate over - Because I don't want to type
Array.prototype.slice.call(document.getElementsByClassName('aVeryNiceClassName'))over and over again
Installation
Install and save to package.json from terminal:
$ npm install --save get-elementget-element is primarily intended for use with a bundler like webpack or browserify:
var getElement = require('get-element')If you need a standalone <script>, though, a minified browser build that attaches to the global namespace as getElement is provided here:
<script src="get-element.min.js"></script>Usage
get-element exports two methods:
getElement.withClass(class, from)
Returns an array of elements with the specified class.
from is an optional parameter to specify a root element other than document.
