How can I programmatically close the Facebook login popup window after the user successfully logs in and authorizes their account?

I’ve been diving into some Facebook API stuff lately, and I’m stuck on a specific issue with the login popup that I thought someone here might have a solution for. So, picture this: I’ve set up a Facebook login flow on my website, and everything’s working pretty smoothly. Users click the “Login with Facebook” button, the popup appears, and they can log in and authorize their accounts. But here’s where I hit a snag.

Once a user successfully logs in, I want to automatically close that popup window. I get that it’s a common usability feature; nobody likes having extra windows hanging around after they’ve completed a task. The problem is, I can’t find a reliable way to achieve this without running into issues. I’ve tried various approaches, but nothing seems to work consistently.

Using JavaScript, I thought I could make use of the `window.close()` method, but that only seems to work if the window was opened programmatically by my script. Since the Facebook login window is generated by their API, I wonder if it falls under a different category where I can’t just close it like that. I’ve also looked into event listeners, trying to catch when the login is successful to trigger the close action, but I’m not having much luck tracking that event effectively either.

I thought about listening for the status change from Facebook after a login attempt, but by the time I think I’ve detected the success, it’s already too late, and the popup is still sitting there waiting for the user to close it manually. That’s just not a great user experience!

So, I’m reaching out to see if anyone has tackled something similar. How can I programmatically close that Facebook login popup window after the user has logged in and authorized their account? Did any of you find a neat trick or workaround for this? Any little snippets or insights would be super helpful. Thanks in advance for your help!

    1. It sounds like you’re encountering a common challenge when integrating the Facebook Login API. The standard behavior for popups created by third-party APIs often prevents direct manipulation via methods like `window.close()` due to browser security restrictions. However, one effective approach is to leverage the Facebook SDK’s built-in event handling. You can monitor the Facebook Login response by utilizing the `FB.getLoginStatus()` method or the callback you provided when invoking `FB.login()`. By checking the response for any successful login status, you can set a function to trigger the closure of your popup window. Use a polling mechanism in your main window to listen for the change in login status, and subsequently alert the child window to close itself.

      Here is a simplified example of how you could implement this: when your main window opens the popup, keep a reference to the window object. Use the `FB.login()` method with a callback that checks for the user’s authentication status. When you detect a successful login, you can call `childWindow.close()` from the main window. Make sure that both the popup and the main window are on the same domain or respect cross-origin policies. Also, adding a slight delay before closing the popup can ensure that the login process completes smoothly and avoids abrupt closure, enhancing the user experience.




    2. Facebook Login Popup Issue

      Facebook Login Popup Question

      So, I totally feel your pain on this one! When I was working with the Facebook API, I bumped into the same issue with closing the login popup. From what I figured out, yeah, `window.close()` is a little tricky because, as you said, it only works for windows your script created.

      One thing you could try is using the Facebook SDK’s response events. When the user logs in, the SDK provides a way to listen for changes in the login status. Here’s a rough idea of how to set it up:

              FB.getLoginStatus(function(response) {
            if (response.status === 'connected') {
                // This means the user has logged in successfully
                // You can close the popup here!
                window.close();
            }
        });

      You’ll need to make sure that this code runs after the user has clicked the “Login with Facebook” button and the popup has opened. It might be in a way that triggers the SDK logins… Just make sure you’re initializing the SDK properly on your page!

      Another thing to watch out for is to ensure the popup isn’t blocked by any browser settings. Sometimes those popups get caught up in the browser’s pop-up blockers, and that can mess with things.

      Also, if you find that `window.close()` still doesn’t work reliably, you might consider just redirecting the user back to your main application page and letting them know success – which is not exactly closing the popup, but it could be a backup option!

      Hope this helps a bit, and good luck getting it sorted out!
