Post by thatsawan »

Code: Select all

<script>
        // This is called with the results from from FB.getLoginStatus().
        function statusChangeCallback(response) {
                console.log('statusChangeCallback');
                console.log(response);
                // The response object is returned with a status field that lets the
                // app know the current login status of the person.
                // Full docs on the response object can be found in the documentation
                // for FB.getLoginStatus().
                if (response.status === 'connected') {
                        // Logged into your app and Facebook.
                        Login_hompage();
                } else if (response.status === 'not_authorized') {
                        // The person is logged into Facebook, but not your app.
                        document.getElementById('status').innerHTML = 'Please log ' +
                                'into this app.';
                } else {
                        // The person is not logged into Facebook, so we're not sure if
                        // they are logged into this app or not.
                        document.getElementById('status').innerHTML = 'Please log ' +
                                'into Facebook.';
                }
        }

        // This function is called when someone finishes with the Login
        // Button.  See the onlogin handler attached to it in the sample
        // code below.
        function checkLoginState() {
                FB.getLoginStatus(function (response) {
                        statusChangeCallback(response);
                });
        }

        window.fbAsyncInit = function () {
                FB.init({
                        appId: '{APP_ID_FACEBOOK}',
                        cookie: true, // enable cookies to allow the server to access 
                        // the session
                        xfbml: true, // parse social plugins on this page
                        version: 'v2.2' // use version 2.2
                });

                // Now that we've initialized the JavaScript SDK, we call 
                // FB.getLoginStatus().  This function gets the state of the
                // person visiting this page and can return one of three states to
                // the callback you provide.  They can be:
                //
                // 1. Logged into your app ('connected')
                // 2. Logged into Facebook, but not your app ('not_authorized')
                // 3. Not logged into Facebook and can't tell if they are logged into
                //    your app or not.
                //
                // These three cases are handled in the callback function.

                FB.getLoginStatus(function (response) {
                        statusChangeCallback(response);
                });

        };

        // Load the SDK asynchronously
        (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'));

        // Here we run a very simple test of the Graph API after login is
        // successful.  See statusChangeCallback() for when this call is made.
        // ส่งค่าจาก facebook มา แสดงว่า login ได้
        function Login_hompage() {
                console.log('Welcome!  Fetching your information.... ');
                FB.api('/me', function (response) {

                        // appid < v.2.4
                        jQuery('#name').val(response.name);
                        jQuery('#email').val(response.email);
                        jQuery('#first_name').val(response.first_name);
                        jQuery('#gender').val(response.gender);
                        jQuery('#id').val(response.id);
                        jQuery('#last_name').val(response.last_name);

                        jQuery('#verified').val(response.verified);
                        jQuery('#updated_time').val(response.updated_time);
                        jQuery('#fbpost').submit();


                        console.log('Successful login for: ' + response.name);
                        document.getElementById('status').innerHTML =
                                'Thanks for logging in, ' + response.name + '!';
                });
        }
</script>

Code: Select all

<fb:login-button scope="public_profile,email" onlogin="checkLoginState();">
</fb:login-button>
อยากได้ตรงนี้ทำงานหลังจากที่คลิกปุ๋ม

Code: Select all

    function statusChangeCallback(response) {
                console.log('statusChangeCallback');
                console.log(response);
                // The response object is returned with a status field that lets the
                // app know the current login status of the person.
                // Full docs on the response object can be found in the documentation
                // for FB.getLoginStatus().
                if (response.status === 'connected') {
                        // Logged into your app and Facebook.
                        Login_hompage();
                } else if (response.status === 'not_authorized') {
                        // The person is logged into Facebook, but not your app.
                        document.getElementById('status').innerHTML = 'Please log ' +
                                'into this app.';
                } else {
                        // The person is not logged into Facebook, so we're not sure if
                        // they are logged into this app or not.
                        document.getElementById('status').innerHTML = 'Please log ' +
                                'into Facebook.';
                }
