javascript倒计时器未在gridview中显示

I have implemented this javascript with a hard coded date and it is displaying properly, I have tried it in a griview but it is rather showing the enddate from my database without showing the countdown, but i want to be getting the enddate from the database: Also, when the countdown is over it should display a message: "Project over" Please friends help me out.

我已经实现了这个带有硬编码日期的javascript并且显示正常，我已经在griview中尝试了它但是它显示了我的数据库的enddate而没有显示倒计时，但我想从数据库中获取enddate：此外，当倒计时结束时，它应显示一条消息：“项目结束”请朋友帮助我。

<script type="text/javascript" src="../Scripts/jquery-3.1.1.min.js"></script>
    <script type="text/javascript" src="../Scripts/jquery.countdown.min.js"></script>
    <script type="text/javascript" src="../Scripts/jquery.countdown.js"></script>


                <asp:TemplateField HeaderText="CountDown" ItemStyle-Width="300px">
                    <ItemTemplate>
                        <div id="myCountdownClass"><%# !string.IsNullOrEmpty(Eval("EndDate").ToString()) ? Convert.ToDateTime(Eval("EndDate")).ToString("MM'/'dd'/'yyyy") : "" %></div>
                    </ItemTemplate>
                </asp:TemplateField>
            </Columns>

        </asp:GridView>

        <script type="text/javascript">
            $(document).ready(function () {
                $('.myCountdownClass').each(function () {
                    var date = $(this).text();
                    $(this).countdown(date, function (event) {
                        $(this).text(event.strftime('%D days %H:%M:%S'));
                    });
                });
            });

        </script>

You specified id in your template, but you're trying to select a class in your javascript ($('.myCountdownClass')). Change this:

您在模板中指定了ID，但是您尝试在javascript中选择一个类（$（'。myCountdownClass'））。改变这个：

<div id="myCountdownClass">

to this:

对此：

<div class="myCountdownClass">

Here's the working example (check script.js file):
