想要在 php 会话变量中保存一个值，喜欢单击，并在用户再次不喜欢显示和隐藏开始按钮时更改会话值。当用户喜欢并刷新页面时，按钮消失了，应该避免这种情况。

var app_id = 'appid';
local = document.getElementById('loc').value;

window.onload = function(){
if (local=="") {
$('#after').css({"display":"none"});
console.log("1");
console.log("local1="+local);

} 
else{
 $('#after').css({"display":"block"});
 console.log("2");
 console.log("local2="+local);

 }
 }
(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
 js.src = "//connect.facebook.net/en_US/all.js#xfbml=1&appId="+app_id;
fjs.parentNode.insertBefore(js, fjs);
 }(document, 'script', 'facebook-jssdk'));


  window.fbAsyncInit = function() {
  FB.init({
  appId : app_id, // App ID
  status : true, // check login status
  cookie : true, // enable cookies to allow the server to access the session
   xfbml : true // parse XFBML
  });

 FB.Event.subscribe('edge.create',
 function(response) {$('#after').css({"display":"block"});
 //$('#local').val('assign');
 //<?php $_SESSION['quiz'] = "assign"; ?>
  local="assign";
  local = <?php $_SESSION['quiz']; ?>
   console.log("3");
   console.log("local3="+local);
  alert(local); 
  }
  );

  FB.Event.subscribe('edge.remove',
  function(response) {$('#after').css({"display":"none"});
  // $('#local').val('assign');
   // <?php $_SESSION['quiz'] = ""; ?>
    local="";
   local = <?php $_SESSION['quiz']; ?>
   console.log("4");
   console.log("local4="+local);
   alert(local);        
    }
   );

    FB.Event.subscribe('auth.login', function() {
    window.location.reload();
     });


    FB.getLoginStatus(function(response) {

    if (response.status === 'connected') {

     // user is logged in and has authenticated your app
    var uid = response.authResponse.userID;
    var accessToken = response.authResponse.accessToken;

    } else if (response.status === 'not_authorized') {

   // user is logged in but has not authenticated your app
    console.log('Logged in no auth');

  } else {


    $('#login').fadeIn();
    $('#login-mask').fadeIn();
    console.log('NOT Logged in');

    }
   });

 $('#login-mask').live('click',function() {
 $('#fb-login').effect('shake', { times:3 }, 300);
 });
 };

使用 Ajax 完成

FB.Event.subscribe('edge.create',
 function(response) {$('#after').css({"display":"block"});
 $.ajax({
   url:"ajax.php",
   type:"post",
   data:{"type":"change"},
   success:function(data){
       console.log("change="+data);
   }

  });
  }
 );

     FB.Event.subscribe('edge.remove',
    function(response) {$('#after').css({"display":"none"});
    $.ajax({
   url:"ajax.php",
   type:"post",
   data:{"type":"again"},
   success:function(data){
       console.log("again="+data);
   }
   });
 console.log("4");
  }
);

.php：- 

  @$type = $_REQUEST['type'];

  if($type == "change"){

$_SESSION['quiz'] = "assign";
echo $_SESSION['quiz'];
 }

 if($type == "again"){

 $_SESSION['quiz'] = "";
 echo $_SESSION['quiz'];
}

 ?>
