用Facebook登錄后如何重定向

Question

我在登錄頁面即具有url參數。 login.php?id=223我想使用Facebook登錄名登錄，我的代碼是

// initialize and setup facebook js sdk
        window.fbAsyncInit = function() {
            FB.init({
              appId      : 'myappid',
              xfbml      : true,
              version    : 'v2.5'
            });
            FB.getLoginStatus(function(response) {
                if (response.status === 'connected') {

                    document.getElementById('login').style.visibility = 'hidden';
                    var id = getUrlParameter('id');
                    alert(id);

                } else if (response.status === 'not_authorized') {
                    document.getElementById('status').innerHTML = 'We are not logged in.'
                } else {
                    document.getElementById('status').innerHTML = 'You are not logged into Facebook.';
                }
            });
        };
        (function(d, s, id){
            var js, fjs = d.getElementsByTagName(s)[0];
            if (d.getElementById(id)) {return;}
            js = d.createElement(s); js.id = id;
            js.src = "//connect.facebook.net/en_US/sdk.js";
            fjs.parentNode.insertBefore(js, fjs);
        }(document, 'script', 'facebook-jssdk'));

        // login with facebook with extra permissions
        function login() {
            FB.login(function(response) {
                if (response.status === 'connected') {





                    document.getElementById('status').innerHTML = 'We are connected.';



                    document.getElementById('login').style.visibility = 'hidden';
                } else if (response.status === 'not_authorized') {
                    document.getElementById('status').innerHTML = 'We are not logged in.'
                } else {
                    document.getElementById('status').innerHTML = 'You are not logged into Facebook.';
                }
            }, {scope: 'email'});
        }

        // getting basic user info
        function getInfo() {
            FB.api('/me', 'GET', {fields: 'first_name,last_name,name,id,email'}, function(response) {
                document.getElementById('status').innerHTML = response.email;
            });
        }
        </script>


    <div id="status"></div>
    <button onclick="getInfo()">Get Info</button>
    <button onclick="login()" id="login">Login</button>

通過單擊登錄按鈕，我成功登錄，並且還將電子郵件提取到狀態字段中，我想知道如何通過url參數和Facebook收到的電子郵件或名稱將頁面重定向到user.php，我認為是用ajax方法實現的我達到了預期的重定向結果
