div没有在表内执行

Question

 <table class="table">
 @foreach (var item in Model)
{
        <tr>
 <td>
               <a href="#countdown" ></a>

                <div id="countdown" class="countdownHolder">
                    <span class="countDays">
                        <span class="position">
                            <span class="digit static"></span>
                        </span>
                        <span class="position">
                            <span class="digit static"></span>
                        </span>
                        <span class="countDiv countDiv3"></span>
                    </span>

                </div>
</td>
            </tr>

}
    </table>

这是我的代码。我需要执行Div以便执行我的jscript。但在运行时，Div被扯掉了。我该怎么办？
