Is it possible to create instance of ClipboardEvent in Chrome?
Unfortunately, it's not. This is from http://caniuse.com/#feat=clipboard
Partial support in IE refers using a non-standard method of interacting with the clipboard. For other browsers it refers to not supporting the ClipboardEvent constructor.
Unfortunately, the only browser that properly supports the Clipboard API is FireFox (since 22). All other browsers (if it supports Clipboard API at all), will not support the ClipbordEvent constructor.
