Question

当vimeo视频结束时，我试图将数据记录到数据库中，以跟踪学生/员工在课程中的时间，并确定他们何时完成课程。当我涉及到js和ajax时，我迷路了。以下是到目前为止我尝试过的。我正在使用laravel 5.6。

如果有人甚至可以将我指向正确的方向，那将会有很大的帮助。

@section('page-title', trans('app.dashboard'))

看来我的js错误，我重写了函数，现在可以正常工作了。

<script>
        $(function() {
            var iframe = $('#display')[0];
            var player = $f(iframe);
            var lesson_id='';
            var lesson_complate_id='';
            // When the player is ready, add listeners for pause, finish, and playProgress
            player.addEvent('ready', function() {
                player.addEvent('pause', onPause);
                player.addEvent('finish', onFinish);
                player.addEvent('playProgress', onPlayProgress);
            });
            $('button').bind('click', function() {
                lesson_id=$(this).data('id');
            });
            function onFinish() {
                console.log('finished');
                $.ajaxSetup({
                    headers: {
                      'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content'),
                      'X-Requested-With': 'XMLHttpRequest'
                    }
                });
                $.ajax({
                    url: '{{route('lesson.complete')}}',
                    method: 'POST',
                    data:  {
                        lesson: lesson_id,
                        user: {{Auth::user()->id}},
                        course: {{$course->id}},

                    },
                    success: function(res){
                        lesson_complate_id ="#lesson_complate_id"+lesson_id;
                        $(lesson_complate_id).attr('class', 'badge badge-success');
                        $(lesson_complate_id).text('Completed')
                    }
                });
            }
