Tiny polyfill for manipulating HTML classes in IE9+ and modern browsers.

Example

Polydom(el).each(function() {
  if (Polydom(this).hasClass('bar')) {
    Polydom(document.getElementById('foo')).toggleClass('baz');
  }
});

Install

May be manually downloaded and linked to like any other JavaScript file, or installed via NPM.

npm install polydom

});

Returns true/false depending on if the element has a class. Throws a TypeError if used on an array or NodeList. Use with each to run checks iteratively.

if (Polydom(el).hasClass('bar)) {
  el.textContent = 'Matching!';
}

Removes a class from DOM elements.
