A ployfill for CustomEvent
This is basically an extended version of the polyfill provided by MDN.
Why another CustomEvent polyfill?
Unfortunately, the MDN polyfill does not cover Browsers < IE 9, including Android Stock Browser on Gingerbread. As I needed support for these browsers and could not find a polyfill that fits this need, I created my own.
Download this repo and include customevent-polyfill.min.js in your project. You can install customevent-polyfill via bower as well.
bower install customevent-polyfill
