javascript - How to read the Clipboard text in google chrome extension

Question

I am trying to read clipboard text in Google chrome extension. As of now I have tried with tis code and it is returning me undefined. Please help me on this.

In background.html my code is

chrome.extension.onRequest.addListener(function(request, sender, sendResponse) {
 if (request.method == "getClipData")
   sendResponse({data: document.execCommand('paste')});
 else
   sendResponse({}); // snub them.
 });

In My content script my code is

chrome.extension.sendRequest({method: "getClipData"}, function(response) {
   alert(response.data);
});

Once upon a time there was an experimental API chrome.experimental.clipboard, but there is no more http://code.google.com/chrome/extensions/trunk/experimental.clipboard.html

Maybe you should try: How do I copy to the clipboard in JavaScript?

UPDATE: I was wrong - there is a possibility. As permissions page says there are "clipboardRead" and "clipboardWrite" permissions. So maybe they will work for you.
