how to write the cookie value to a variable in the background page, went like this:
var ccc=chrome.cookies.get({"url": " vk.com ", "name": "1"}, function(cookies){
callback(cookies .value);
});
alert(ccc);
writes that he does not find

Answer 1

The call is asynchronous, because the ccc variable will not have a value (well, or it will obviously not be what you expect). Catch in the callback function and do what you need there.

Answer 2

I don’t understand what the background page means, but judging by the presence of vk.com, it probably means cross-domain cookie fencing. If so, then the answer is no.
