ajax event

[Pink-El]

Hello,

I need create facebook login in my app.

I added fblogin.js to the custom files

When I use the following  code <fb:login-button scope="public_profile,email" onlogin="checkLoginState();"></fb:login-button><div id="status"></div>

On click event back me with a result to the java function  on the page

function testAPI(userID) {
    console.log('Welcome!  Fetching your information.... ');
    FB.api('/me', function(response) {
          ajaxRequest(MainmForm, 'fblogin', []);
      document.getElementById('status').innerHTML =
        'Thanks for logging in, ' + response.name+' ID '+userID +'!';
    });
}

I tried to generate ajax event but I`ve got error message Event:fblogin Object not found in session list

How to fix it?

 

fblogin.js

// JavaScript Document

  // 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.
	  var uid = response.authResponse.userID;
	  //var uname = response.name;	  
	  // alert(uname);
	  // alert(uid);
      testAPI(uid);
    } 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      : '1558074717851346',
    cookie     : true,  // enable cookies to allow the server to access 
                        // the session
    xfbml      : true,  // parse social plugins on this page
    version    : 'v2.5' // 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.
  function testAPI(userID) {
    console.log('Welcome!  Fetching your information.... ');
    FB.api('/me', function(response) {
       // if (response.id) {
       //     var facebook_userid = response.id;
       // }
          ajaxRequest(MainmForm, 'fblogin', []);
 	  //var uid = response.authResponse.userID;
	  //console.log('Successful login for: ' + response.name);
      document.getElementById('status').innerHTML =
        'Thanks for logging in, ' + response.name+' ID '+userID +'!';
    });
  }

Hi,

Well, it`s good code but I can not to understand how implement third-party script with existing page. In my example some java script functions plugin to the page and I just need back some values. The simple way to generate ajax event with parameters and catch there on the server. As far as I can see the problem with first parameter of the ajax event. I need to get UserID and Username for the login.

Mainmform is unknow object. Window and document are ok but server part does not catch event. I am lost a little
