In previous post I explained how to integrate facebook login to asp.net website and get user details from facebook in asp.net. During working with these concepts I got problem to refresh webpage after facebook login or logout to get updated details of user.
In facebook we have two functions FB.Login() and FB.logout()
FB.Login():
This function is used to allow users
login with facebook account and this function will refresh our webpage after
login with facebook account then we have a chance to display updated user
details in our webpage.
FB.Logout():
This function is used to logout the
current user session from facebook but it won’t refresh the page because of
that we don’t have a chance to show updated userdetails on webpage.
To solve this problem we need to write FB.Logout function like this
FB.logout(function()
{
window.location.reload();
});
|
Or
FB.logout(function()
{
window.location=’path/url here’;
});

FB.Event.subscribe('auth.statusChange',
function(response) {
if (response.authResponse) {
// user has auth'd your app and
is logged into Facebook
FB.api('/me',
function(me) {
if (me.name) {
document.getElementById('auth-displayname').innerHTML = me.name;
}
})
document.getElementById('auth-loggedout').style.display = 'none';
document.getElementById('auth-loggedin').style.display = 'block';
} else {
// user has not auth'd your app,
or is not logged into Facebook
document.getElementById('auth-loggedout').style.display = 'block';
document.getElementById('auth-loggedin').style.display = 'none';

$("#auth-loginlink").click(function() { FB.login(); });
$("#auth-logoutlink").click(function() { FB.logout(function()

If you observe above code I written
$("#auth-loginlink").click(function() { FB.login(); });
$("#auth-logoutlink").click(function() { FB.logout(function()
{ window.location.reload(); });
|
I am using FB.login and FB.logout
functions in click events to handle signin and signout options for our
application.
Now run your application and check the
output that would be like this
