<script src="../../Scripts/ValidDing.js" type="text/javascript"></script>

$(document).ready(function () {
    $("#ImgD").click(function () {

js代码直接放到html页面可以执行，单独放到js文件再引用却执行不了，？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？？

但是如果我这样却可以执行：

function   ImgDfunction（）{}

源代码：

  @foreach (var item in Model)
    { 
                <script type="text/javascript">
                    $(document).ready(function () {
                        $("#ImgD").click(function () {
                            var MeId = $("input").val();
                            $.ajax({
                                type: "Get",
                                url: "/Main/IsDingOrCai",
                                data: "q=ding&MeId=" + MeId,
                                success: function (msg) {
                                    if (msg == "Sorry") {
                                        alert("对不起，您已经对这段笑话表过态了！");
                                    }
                                    if (msg == "Ok") {
                                        alert("谢谢你的参与");
                                    }
                                }
                            })
                        });
                        $("#ImgC").click(function () {
                            $.ajax({
                                type: "Get",
                                url: "/Main/IsDingOrCai",
                                data: "q=cai",
                                success: function (msg) {
                                    if (msg == "Sorry") {
                                        alert("对不起，您已经对这段笑话表过态了！");
                                    }
                                    if (msg == "Ok") {
                                        alert("谢谢你的参与!");
                                    }
                                }
                            });
                        });
                    });
                </script>
                <div class="RoundedCorner" style="z-index: auto; width:500px; margin-bottom:20px; background-color:White; margin-left:50px; padding-left:20px">
                       <br /><br />
                       <h4> @Html.Raw(item.Title)</h4>
                       <br />
                       <br />
                             @Html.Raw(item.Message)
                       <br />
                       <div id="divSign"  style=" text-align:right; margin-right:30px">
                            <input type="hidden" id="@item.MeId" value="@item.MeId" />
                            <img id="ImgD" style="cursor:pointer" alt="" src="/Content/themes/base/images/85.gif"/>
                            @Html.Label(item.dingCount.ToString())
                            <img id="ImgC" style="cursor:pointer" alt="" src="/Content/themes/base/images/86.gif" />
                            @Html.Label(item.caiCount.ToString())
                       </div>
                </div>

这样可以执行......但是页面输出的三个DIV，只有第一个Div中的Img可以触发js函数，下面两个DIV中的IMG怎么点也触发不了
