Created attachment 255609 [details] Test case Chrome 43 decides that allowing the website to pollute your clipboard inside _any_ DOM event handler is no longer a concern. http://codetheory.in/javascript-copy-to-clipboard-without-flash-using-cut-and-copy-commands-with-document-execcommand/ Can WebKit consider allowing the same? Test case attached.

Letting webpages _write_ into the clibpard while the user is interactiving with the page seems okay.

Yes, writing only. Looks like this will be implemented in Firefox 41 too. https://bugzilla.mozilla.org/show_bug.cgi?id=1012662

This would allow Github.com to stop using Flash on WebKit: <https://twitter.com/davidgraham/status/692075210435010561>

There is certainly no shortage of websites that are using Flash for this purpose, github possibly not even being the most prominent. Personally, I'm not looking forward to a world in which advertisers put their content on my pasteboard each time a click a webpage.

(In reply to comment #10) > Yay! Thanks Sam! My pleasure! Any chance we can get Github updated to check document.queryCommandSupported("copy") to add the copy button :).
