Getting cookies in a google chrome extension

Question

I am trying to get a cookie specifically from a domain using this code:

Answer 1

Almost all Chrome API calls are asynchronous, so you need to use callbacks to run code in order:

function getCookies(domain, name, callback) {
    chrome.cookies.get({"url": domain, "name": name}, function(cookie) {
        if(callback) {
            callback(cookie.value);
        }
    });
}

//usage:
getCookies("http://www.example.com", "id", function(id) {
    alert(id);
});
