如何在AJAX中重定向用户？

Question

我正在使用FacebookSDK4.0。我在代码点火器中有一个登录页面，使用Ajax发送和接收请求、登录用户。

我想让用户使用Facebook登录，但我没找到方法。我有一个控制器函数表单，名为facebook_login。我在递交这份表格时有一份javascript代码：

$('.facebook_login').submit(function() {       
    var errors = $(this).find('.errors');
    var success = $(this).find('.success');
    var overlay = $(this).find('.overlay');

    overlay.fadeIn(300);
    errors.fadeOut('fast');
    success.fadeOut('fast');

    var url = $(this).attr('action');
    var data = $(this).serialize();

    $.ajax({
        url: url, //url = path to which form should be submitted
        type: 'POST', //POST = form method
        dataType: 'json', //json - data type in which server is supposed to send response
        data: data,
        success: function(response) { //response = reply sent by server after processing our request
            if (response.status == true)
            {
                errors.fadeOut('fast');
                overlay.fadeOut('fast');
                success.html(response.message).fadeIn('fast').delay(300).fadeOut(function(){
                    window.location =response.redirect;
                });
            }
            else
            {
                success.fadeOut('fast');
                overlay.fadeOut();
                errors.html(response.message).fadeIn('fast');
            }
        },
        error: function() {
            overlay.fadeOut();
        }
    });
    return false;
});

函数facebook_login执行以下操作：

session_start();
$this->load->library('facebook');

$user_logged_in = $this->facebook->logged_in();

//check if the user is already logged in with facebook
if(!$user_logged_in){
    //if the user is not logged in
     $loginUrl = $this->facebook->login_url();   
}

我想重定向用户以登录到Facebook，然后重定向回网站，保存会话，并使用以下命令显示错误/成功警报：

header('Content-Type: application/json');
echo json_encode($response);

Simply use javascript redirect.

 location.href = "http://some.com/your path";
