How to implement Facebook Graph API Logout function to logout from your web appliaction with your facebook session and remove all related cookies

On your js file :-

function logout(){

FB.getLoginStatus(handleFBSessionResponse);

location.href = '/user_sessions/new';

}

// handle a session response from any of the auth related calls

function handleFBSessionResponse(response) {

/*

//Check the facebook login status

alert("handleFBSessionResponse(), "

+ "\nresponse.status="+response.status

+" \nresponse.session="+response.session

+" \nresponse.perms="+response.perms);

*/

//if we do have a non-null response.session, call FB.logout(),

//the JS method will log the user out

//of Facebook and remove any authorization cookies

FB.logout(handleFBSessionResponse);

}

on your html file :-

< href="javascript:logout();">Logout< / a >
