单击浏览器的后退按钮时如何销毁会话

Question

我正在使用 laravel 中的 session->flash() 方法闪烁成功消息。 但是当用户单击后退按钮时，消息再次出现。 如何解决这个问题。 我显示消息的代码是 -

@if(Session::get('success') )
    <script>
        swal({
            text: "{{Session::get('success')}}",
            button: localMsg.ok,

        }).then((isConfirm) => {
        });
    </script>
    @elseif(Session::get('error'))
    <script>
        swal({
            text: "{{Session::get('error')}}",
            button: localMsg.ok,

        }).then((isConfirm) => {
        });

    </script>
@endif

Answer 1

您应该销毁会话值以获得成功和错误消息

@if(Session::get('success') )
    <script>
        swal({
            text: "{{Session::get('success')}}",
            button: localMsg.ok,

        }).then((isConfirm) => {
        });
     {{ Session::forget('success'); }} //Add this line to destroy value for 'success'
    </script>
    @elseif(Session::get('error'))
    <script>
        swal({
            text: "{{Session::get('error')}}",
            button: localMsg.ok,

        }).then((isConfirm) => {
        });
     {{ Session::forget('error'); }} //Add this line to destroy value for 'error'
    </script>
@endif

通过这种方式，您可以获得浏览器的返回按钮事件：

     if (window.history && window.history.pushState) {

        window.history.pushState('forward', null, './#forward');

        $(window).on('popstate', function() {
          alert('Back button was pressed.'); //here you know that the back button is pressed
        //write code to hide your success message when your clicks on browser back button

        });

      }
