I am trying to add events information to the facebook users profile from a 3rd party website using Javascript SDK provided by facebook. I just googled for few tutorials and I got this links

I tried with the combination of login logout and session handling

When I click on the add event page I am getting "undefined". Iam not able to add events to facebook profle. Kindly help me

I would try your code again, and maybe console.log(resp) in your callback method for the addevents function. I tested your code on fbrell.com and it seemed to work perfectly and as expected.

edit: after a little research (and your fixed code..) I found that the fb:login button doesn't ensure that your application has the correct permissions that the perms parameter requests. We find this out when we do a Graph request and it fails. So we catch the error, and then launch the Login modal via the FB.login method, and ask for the create_event permission. When the user accepts that dialog, we retry creating the event.

<fb:login-button
    autologoutlink="true" 
    perms="email,user_birthday,status_update,publish_stream,create_event">
</fb:login-button>
<a href="#" id="create_event" onclick="create_event();">create</a>

<script>
FB.XFBML.parse();
document.getElementById('create_event').onclick = function() { create_event(); }
function create_event()
{
    FB.api('/me/events', 'post', {
        name:          "JS-SDK Event",
        start_time:    1272718027,
        location:      "Anywhere USA",
        privacy_type:  "OPEN"
    }, function(resp) {

        if (typeof resp.error != 'undefined')
        { /*this failed. most likely because we don't have the extended permission
            for create_event. so lets check for it, ask for it, and try to create
            the event again.  but first, we'll make sure that the error message says
            something about 'create_event' so we don't launch an infinite loop
          */
            if (resp.error.message.match(/create_event/))
            {
                FB.login(function(response)
                {
                    if (response.session 
                        && response.status == 'connected' 
                        && response.perms.match(/create_event/))
                    {
                        //this user is connected & we have create event permission.
                        create_event();
                    }
                },
                {
                    perms: 'create_event'
                });
            }
        }    
    });
}
