会话过期后的Jquery警报框

Question

我有代码

if(isIdleTimeExceeded())
{
    logout();
    header("Location:".$baseurl."index.php");
    exit();
}

在IdleTimeExceeded中我正在检查时间。

我想在会话到期后获得jQuery警告框。

Answer 1

您发布的代码是PHP代码。但是在页面被发送到客户端之后，您将无法再访问php函数。如果空闲时间意味着用户没有在几秒钟内切换页面，那么您只需要javascript。

<script>
//the function IdleToLong will be called after 30seconds. 
//This means if the page reloads, it starts over.
setTimeout(IdleToLong, 30 * 1000); // 30 seconds

function IdleToLong() {
  alert('Move your ass');

  //If you also need to logout in PHP then you must notify the server that a user has been idle to long.
  $.get('logout.php?reason=idle').complete(function() { 
     window.location.href = '/';
  });
}
</script>

使用javascript创建警报 echo '<script type="text/javascript">alert("Logged out!!");</script>';
