javascript - SQL/C# DateTime 转换为 Javascript 变量

Question

我想要制作 JavaScript 倒计时，它以 SQL Server DateTime 作为结束时间，以 C# 日期时间作为时间，我将从 SQL Server Endtime 中减去这里是代码

            <script>

            var EndTime = @Context.Session.GetString("EndTime");

            var nowtime = @DateTime.Now.ToString();

            var difference = EndTime - nowtime;

            var initialTime = difference ;

            var seconds = initialTime;
            function timer() {
                var days = Math.floor(seconds / 24 / 60 / 60);
                var hoursLeft = Math.floor((seconds) - (days * 86400));
                var hours = Math.floor(hoursLeft / 3600);
                var minutesLeft = Math.floor((hoursLeft) - (hours * 3600));
                var minutes = Math.floor(minutesLeft / 60);
                var remainingSeconds = seconds % 60;
                if (remainingSeconds < 10) {
                    remainingSeconds = "0" + remainingSeconds;
                }
                document.getElementById('countdown').innerHTML = days + "dias " + hours + "horas " + minutes + "minutos " + remainingSeconds + "segundos";
                if (seconds == 0) {
                    clearInterval(countdownTimer);
                    document.getElementById('countdown').innerHTML = "Completed";
                } else {
                    seconds--;
                }
            }
            var countdownTimer = setInterval('timer()', 1000);

        </script>


<span id="countdown" class="timer"></span>

@Context.Session.GetString("EndTime") 这是来自 SQL Server 的日期时间

以这种方式向 Javascript 添加日期时间不起作用，需要一些帮助，谢谢。

<span id="countdown" class="timer"></span>

<script>


            var t1 = "@Context.Session.GetString("EndTime")";
            var endTime = new Date(t1);

            var t2 = "@DateTime.Now.ToString()";
            var nowTime = new Date(t2);

            var initialTime = (endTime - nowTime)/1000;

            var seconds = initialTime;
            function timer() {
                var days = Math.floor(seconds / 24 / 60 / 60);
                var hoursLeft = Math.floor((seconds) - (days * 86400));
                var hours = Math.floor(hoursLeft / 3600);
                var minutesLeft = Math.floor((hoursLeft) - (hours * 3600));
                var minutes = Math.floor(minutesLeft / 60);
                var remainingSeconds = seconds % 60;
                if (remainingSeconds < 10) {
                    remainingSeconds = "0" + remainingSeconds;
                }
                document.getElementById('countdown').innerHTML = days + "dias " + hours + "horas " + minutes + "minutos " + remainingSeconds + "segundos";
                if (seconds == 0) {
                    clearInterval(countdownTimer);
                    document.getElementById('countdown').innerHTML = "Completed";
                } else {
                    seconds--;
                }
            }
            var countdownTimer = setInterval('timer()', 1000);

        </script>

我记得我是如何做到这一点的，谢谢大家。
