I'm currently building a web application that is a translation of another program I wrote in visual basic long ago. In visual basic there was the ability to put data directly into the operating system's clipboard. Is there functionality to do this in chrome? I've tried:

var magicevent = new ClipboardEvent('copy', { dataType: 'text/plain', data: 'Data to be copied' } );
document.dispatchEvent(magicevent);

however Chrome gives me and Illegal constructor error, while tells me I should be able to use the clipboard API?

• I don't think you need the document.dispatchEvent(magicevent);. Try removing it. – Ismael Miguel Commented May 24, 2015 at 0:58
• Still get "Uncaught TypeError: Illegal constructor" :( – Tyler Commented May 24, 2015 at 1:00
• Sorry the delay to say something. You should check this: stackoverflow./questions/28861479/… – Ismael Miguel Commented May 24, 2015 at 1:42

I have searched a lot for a solution, since this is the first time using this lib. However thanks to our lovely chinese friends, they pointed out the solution for this error.

Solution: clipboard.js has been tweaked and can use global ClipboardJS to prevent conflicts. Such as:

var clipboard = new ClipboardJS('#btn');

The ClipboardEvent constructor cannot be instantiated in Chrome as of version 51. See the relevant caniuse page for details, and make sure to read the functional notes.

More specifically:

Does not support the ClipboardEvent constructor
