  • Can you call FB.login inside a callback from other FB methods (like FB.getLoginStatus) without triggering popup blockers?

    - by Erik Kallevig
    I'm trying to set up a pretty basic authentication logic flow with the FB JavaScript SDK to check a user's logged-in status and permissions before performing an action (and prompting the user to login with permissions if they are not)... User types a message into a textarea on my site to post to their Facebook feed and click's a 'post to facebook' button on my site. In response to the click, I check user's logged in status with FB.getLoginStatus In the callback to FB.getLoginStatus, if user is not logged in, prompt them to login (FB.login). In the callback to FB.login I then need to make sure they have the right permissions so I make a call to FB.api('/me/permissions') -- if they don't , I again prompt them to login (FB.login) The problem I'm running into is that anytime I try to call FB.login inside a callback to other FB methods, the browser seems to lose track of the origin of execution (the click) and thus will block the popup. I'm wondering if I'm missing some way to prompt the user to login after checking their status without the browser mistakenly thinking that it's not a user-initiated popup? I've currently fallen back to just calling FB.login() first regardless. The undesired side effect of this approach, however, is that if the user is already logged-in with permissions and I'm still calling FB.login, the auth popup will open and close immediately before continuing, which looks rather buggy despite being functional. It seems like checking a user's login status and permissions before doing something would be a common flow so I feel like I'm missing something. Here's some example code. <div onclick="onClickPostBtn()">Post to Facebook</div> <script> // Callback to click on Post button. function onClickPostBtn() { // Check if logged in, prompt to do so if not. FB.getLoginStatus(function(response) { if (response.status === 'connected') { checkPermissions(response.authResponse.accessToken); } else { FB.login(function(){}, {scope: 'publish_stream'}) } }); } // Logged in, check permissions. function checkPermissions(accessToken) { FB.api('/me/permissions', {'access_token': accessToken}, function(response){ // Logged in and authorized for this site. if (response.data && response.data.length) { // Parse response object to check for permission here... if (hasPermission) { // Logged in with permission, perform some action. } else { // Logged in without proper permission, request login with permissions. FB.login(function(){}, {scope: 'publish_stream'}) } // Logged in to FB but not authorized for this site. } else { FB.login(function(){}, {scope: 'publish_stream'}) } } ); } </script>

  • iPhone Application failing to come back from sigkill

    - by overscore
    I have no idea if this is intended behaviour, but whenever the application exits (say, the user is double-clicking the home button and pressing on the red dash on the icon) I get the dreaded SIGKILL. Now, when I try to launch the app again all I get is the old screen state and a frozen (I presume ?) program. It could be because of clunky memory management, but NSZombieEnabled doesn't seem to agree. Any thoughts ?

    - by CShipley
    When you scroll down to the bottom of http://www.dzone.com/links/ it automatically loads more links. However, when you navigate away, then hit the back button, the contents of the modified div stay there. How do they get the browser to go back to a dynamically generated div?

  • Redirect on a SWFObject when Full Screen is clicked?

    - by maguidhir
    I am using JavaScript to display a swf video, and I want to override the Full Screen button if possible, so that it redirects to another url instead of making the video full screen. Is there a parameter that I can pass to the SWFObject that will allow me to do this? I would appreciate any help. Thanks.

  • Game doesn't Quit properly

    - by W.K.S
    I have an app that so far consists of two Activities: The Main Menu Activity. The Game Activity The Main Menu Activity contains a button that starts the Game Activity with the following code: public void onClick(View clickedButton) { switch(clickedButton.getId()) { case R.id.buttonPlay: Intent i = new Intent("apple.banana.BouncingBallActivity"); startActivity(i); break; } When the user is done with the Game Activity, he presses the back button. This calls the onPause() method first, which pauses the animation thread of the game. It then calls the onStop() which calls finish() on the activity altogether. The user is returned to the Main Menu activity. The code is outlined below: public class BouncingBallActivity extends Activity{ private BouncingBallView bouncingBallView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); bouncingBallView = new BouncingBallView(this); bouncingBallView.resume(); setContentView(bouncingBallView); } @Override protected void onPause() { super.onPause(); bouncingBallView.pause(); } @Override protected void onResume() { super.onResume(); bouncingBallView.resume(); } @Override protected void onStop() { super.onStop(); this.finish(); } } The problem is that this only works if I launch the application from Eclipse. When I click on the app icon, the game starts from the Game Activity. The main menu activity does not appear. I am not clear about why this happens. It could be something to do with the manifest. I've pasted the relevant portions below: <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <activity android:name=".BouncingBallActivity" android:label="@string/app_name" android:screenOrientation="landscape" > <intent-filter> <action android:name="apple.banana.BouncingBallActivity" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity> <activity android:name=".MainMenu" android:label="@string/app_name" android:screenOrientation="portrait" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> I'd really appreciate any help with this. Thanks.

  • How to implement a login page in a GWT app?

    - by Gatis
    My WebApp needs to authenticate user before allowing any sort of access. The scenario I'm trying to implement is a login page with username and password fields. Once user hits "send" button, a sign like "Verifing..." should be shown up while an RPC call verifies credentials. In case of success, load the main app screen. What is the best way to implement that?

  • Help with simple frame, and graphics in Java

    - by Crystal
    For hw, I'm trying to create a "CustomButton" that has a frame and in that frame, I draw two triangles, and a square over it. It's supposed to give the user the effect of a button press once it is depressed. So for starters, I am trying to set up the beginning graphics, drawing two triangles, and a square. The problem I have is although I set my frame to 200, 200, and the triangles I have drawn I think to the correct ends of my frame size, when I run the program, I have to extend my window to make the whole artwork, my "CustomButton," viewable. Is that normal? Thanks. Code: import java.awt.*; import java.awt.event.*; import javax.swing.*; public class CustomButton { public static void main(String[] args) { EventQueue.invokeLater(new Runnable() { public void run() { CustomButtonFrame frame = new CustomButtonFrame(); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setVisible(true); } }); } } class CustomButtonFrame extends JFrame { // constructor for CustomButtonFrame public CustomButtonFrame() { setTitle("Custom Button"); setSize(DEFAULT_WIDTH, DEFAULT_HEIGHT); CustomButtonSetup buttonSetup = new CustomButtonSetup(); this.add(buttonSetup); } private static final int DEFAULT_WIDTH = 200; private static final int DEFAULT_HEIGHT = 200; } class CustomButtonSetup extends JComponent { public void paintComponent(Graphics g) { Graphics2D g2 = (Graphics2D) g; // first triangle coords int x[] = new int[TRIANGLE_SIDES]; int y[] = new int[TRIANGLE_SIDES]; x[0] = 0; y[0] = 0; x[1] = 200; y[1] = 0; x[2] = 0; y[2] = 200; Polygon firstTriangle = new Polygon(x, y, TRIANGLE_SIDES); // second triangle coords x[0] = 0; y[0] = 200; x[1] = 200; y[1] = 200; x[2] = 200; y[2] = 0; Polygon secondTriangle = new Polygon(x, y, TRIANGLE_SIDES); g2.drawPolygon(firstTriangle); g2.setColor(Color.WHITE); g2.fillPolygon(firstTriangle); g2.drawPolygon(secondTriangle); g2.setColor(Color.GRAY); g2.fillPolygon(secondTriangle); // draw rectangle 10 pixels off border g2.drawRect(10, 10, 180, 180); } public static final int TRIANGLE_SIDES = 3; }
