Facebook oauth弹出窗口被浏览器阻止

Question

请帮助，我的代码中有什么问题，因为浏览器阻止会弹出Facebook窗口。我不知道。在某些浏览器中它被阻止，有时候还可以。我应该找出解决方法。

/*facebook oauth*/
$('#oauth_facebook').on('click', function (event) {
    event.preventDefault();
    window.fbAsyncInit = function () {

        FB.init({
            appId: 'ххххххххххх',
            cookie: true,
            xfbml: true,
            oauth: true
        });

        FB.getLoginStatus(function (response) {
            console.log('sucsess');
            if (response.status === 'connected') {
                var accessToken = response.authResponse.accessToken;
                var userID = response.authResponse.userID;
                var userName, userEmail;
                var url = '/me?fields=name,email,picture.width(300).height(300)';
                var avatar;
                FB.api(url, function (response) {
                    userName = response.name;
                    userEmail = response.email;
                    avatar = response.picture.data.url;
