Polyfill for classList methods (contains, add, remove, toggle) on SVG elements which aren't supported on IE11 and other older browsers.
npm install svg-classlist-polyfill
import 'svg-classlist-polyfill'
That's it, polyfill will only be added if current environment doesn't already support the methods. Here is how regular usage afterwards might look like:
const icon = document.querySelector('svg.icon')
icon.classList.add('icon--blue')
icon.classList.toggle('icon--rotate')
icon.classList.remove('icon--blue')
icon.classList.contains('icon--blue') === false
Avoid setting the class with icon.className = 'icon icon--blue'
as this isn't properly supported in IE11 and will not work together with the polyfill.
There are a few test cases available in test.js
. Serve a simple website with npm test
opening this in a browser will run a few test cases quickly indicating whether the polyfill is working well.
