Handy JavaScript without the jQueries, et al.

Not much to say here, but UtilityBelt.js is a simple wrapper to support common tasks that rely on classNames. What does it do? Glad you asked!

Features

  • Instantiate with const belt = new UtilityBelt(); or whatever.
  • Add a class name to an element with belt.addClassName(className, el);.
  • Remove a class name from an element with belt.removeClassName(className, el);
  • See whether an element has a certain class name with belt.hasClassName(className, el);.
  • Get all elements that have a certain class name with belt.getElementsByClassName(className, element); (element defaults to document).
  • Add an event listener with belt.addEventListener(eventTarget, event, callback, capture); (capture defaults to false).
  • Fire a function when the DOM has loaded (before window.onload) with belt.onDOMReady(callback);.

N.b.: This set of utilities is offered as-is (for now). Eventually I might get it set up for use with Babel or other tools that convert ES2015 classes into objects and handle arrow functions. Right now this project exists as an intellectual exercise and to keep track of current and historical approaches to dealing with class names in JavaScript.
