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
jQuery
just to select elements is like using a flamethrower to light a birthday candle - Because
document.querySelector()
is slow - Because
HTMLCollections
are cool and all, but I usually want an actualArray
to 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-element
get-element
is primarily intended for use with a bundler like webpack or browserify:
var getElement =
If you need a standalone <script>
, though, a minified browser build that attaches to the global namespace as getElement
is provided here:
Usage

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
.
<!--index.html-->
// main.js (pre-bundle)var el = var foo = el // => [ <div.foo> ] var bar = el // => [ <div.bar>, <section.bar>, <section.bar> ] var fooBar = el // => [ <div.bar> ]
getElement.withTag(tag, [from])
Returns an array of elements with the specified tag.
from
is an optional parameter to specify a root element other than document
.
