Small js which handles facebook connect implementation for PhoneGap, JavaScript.

##Usage

• Login Prompt: Fist of all we need to call prompt login, which will use FB.login() to generate in app login screen. It takes scope as parameter. see official documentation.

function promptLogin() {
    FB.login(null, {
        scope: 'email'
    });
}

• Authenticate User After Login: Will handle different state changes.

function authUser() {
    FB.Event.subscribe('auth.statusChange', handleStatusChange);
}

• Getting User Data: After successful authentication call FB.api(path, method, params, callback) it will make Graph API call to get user details. Check response format to access data. see official documentation.

/* /me/ will get default information of user. 
change it /me/conversations/, '/me', {fields: 'last_name'} etc as per usage */
FB.api('/me/', function(response) {
  console.log(JSON.stringify(response));
}

• Get Profile Picture: We can get different size of image by specifying width and height during FB.api() call.

FB.api("/me/picture?width=180&height=180", function(response) {
  var imageurl=response.data.url;
}

• Update on User Feed/Status Update: This method is used to trigger different forms of Facebook created UI dialogs FB.ui(params, function(response)) see official documentation.

            method: 'feed',
            caption: 'Message From FB-Connect-JS',
            picture: 'http://www.freelargeimages.com/wp-content/uploads/2014/11/Facebook_logo-6.jpg',
