bling.js

Because you want the $ of jQuery without the jQuery.


You may be interested in bling.js if you get tired of the [].slice.call( document.querySelectorAll('.foo'), function(){ … rodeo. It does this:

// forEach over the qSA result, directly.
document.querySelectorAll('input').forEach(el => /* ... */);

// on() rather than addEventListener()
document.body.on('dblclick', evt => /* ... */);

// classic $ + on()
$('p').on('click', el => /* ... */);

It doesn't do anything else. This is not a jQuery equivalent.

Notes:

  • on() works on elements, document, window, and results from querySelector & querySelectorAll.
  • $ is qSA so if you're grabbing a single element you'll have to [0] it.
  • Bling plays well with authoring ES6
  • Resig explored this stuff a while ago: github.com/jeresig/nodelist
  • Bling doesn't work on Android 2.3 or iOS 5.0. Works everywhere else including IE8 (assuming Function.bind)

Nerdy implementation notes:

  • The NodeList prototype usually inherits from Object, so we move it to Array.
  • I'm curious how ES6/7 would let a NodeList be iterable and inherit from EventTarget
  • Setting Node.prototype.on = EventTarget.prototype.addEventListener is awesome. It works in Chrome/FF but not yet in IE/Safari.
  • I haven't set up any off() or trigger() to map to dispatchEvent & removeEventListener. I'm OK with that.
  • I'm using semi-standard for style. I tried standard sans-semicolons, but can't get used to it.
/* bling.js */
window.$ = document.querySelectorAll.bind(document);
Node.prototype.on = window.on = function (name, fn) {
this.addEventListener(name, fn);
}
NodeList.prototype.__proto__ = Array.prototype;
NodeList.prototype.on = NodeList.prototype.addEventListener = function (name, fn) {
this.forEach(function (elem, i) {
elem.on(name, fn);
});
}

What about changing the prototype of HTMLCollection as well so they are easier to iterate over? You can find HTMLCollection's in properties like ParentNode.children

Not sure of the side effects, yet.

HTMLCollection.prototype.__proto__ = Array.prototype;

put code in github repo - https://github.com/stevermeister/bling.js/blob/master/bling.js
to make it open & conveninent for contribution

Better $ to querySelector and $$ to querySelectorAll instead of $('.something')[0].on(...).

Inspired by this to make a version here https://github.com/dosaygo-coder-0/postjs/blob/master/postbling/src/postbling.js

What's new?

  • on applies to EventTargets and Arrays containing them, so you can do this:
$('*').slice(3).on('click', reveal );
$`div`.on( 'touchstart', dragOn ).on( 'touchend', dragOff );
  • NodeList and HTMLCollection both now delegate to Array
  • the on functions return this to allow chaining
  • and made it more ES5/6/7-y including Object.setPrototypeOf

These included ideas from @MadLittleMods and @spiralx and @joa

@bjankord awesome. thanks for the tip. Sadly some of us do have to support IE9... 🎉

This does NOT work for DOM elements inside iframes. Here's the related SO question with a related code sample - based on the same principles as above code - with a reproducible example - http://stackoverflow.com/questions/42825990/extending-prototype-of-dom-elements-inside-iframes
Any ideas anyone?

Is this safe to use in production?

@Ollie-w yeah totally.

I think I have an interesting fork:

  • only mutates the nodes queried with the exported function
  • offers 'off'
  • offers nice attribute CRUD operations

@AdaRoseCannon has a nice extension of this idea which maps ALL things in the Element prototype onto the NodeList prototype https://gist.github.com/AdaRoseCannon/d95a7cbb8edd730443c62f0daff875ac
