I wanna make a extension to copy selection to clipboasd by clicking the ContextMenu. In chrome,many people use a flash solusion.But how can use flash in ContextMenus.It seems impossible.Who can tell me a solusion?

What I did

var a = chrome.contextMenus.create({"title":copy,"context":["selection"],"onclick":copy});
function copy(info,tab){
document.execCommand('selectAll'); //just for example
document.execCommand('copy');
}

I have add clipboardWrite permisson to manifest.json.But it seems doesn't work. "permission":["contextMenus","clipboardWrite"]

• The Experimental Clipboard API has been removed and chrome doesn't support document.execCommand("Copy") and how can I use a flash in ContextMenus. – user1309417 Commented Apr 3, 2012 at 3:45
• May be the experimental API is no longer experimental? code.google./chrome/extensions/manifest.html#permissions – Alejandro Silvestri Commented Apr 3, 2012 at 3:47

Add this permission into your manifest.json:

"permissions": [ "clipboardWrite" ]

And to copy to clipboard:

document.execCommand('copy', false, null);

May be this helps. A recent addition to manifest's permissions are clipboardRead and clipboardWrite. Theese let your extension to use the method document.execCommand('copy'), for example.
