    <div id="dialog">   
            <table>
                <tr>
                    <td>User ID</td>
                    <td>@ViewBag.UserID</td>
                </tr>
                <tr>
                    <td>Comments</td>
                    <td>@Html.TextArea("CommentsTextBox")</td>
                </tr>
            </table>
            <div class="alignCenter"> 
                 <input type="submit" value="Add" /> 
                 <input type="button" value="Cancel" /> 
            </div>
    </div>

Answer 1:

您的代码应该有工作，但可能是jQuery的对话框的div改变DOM元素值<div id="dialog">

你可以试试下面的方法。

请用户ID的隐藏字段。

<input type="hidden" id="userId" value="@ViewBag.UserID" />

让里面的用户ID占位符<div id="dialog">

<div id="dialog">
    <table>
        <tr>
            <td>User ID</td>    
            <td><span id="dialogUserId"></span></td>
        </tr>
    </table>
</div>

获取用户名和上OpenDialog（）事件分配形式占位符。

<script>
function OpenDialog()
    {
        $("#dialogUserId").val($("#userId").val()); //if this won't work try adding this line after dialog("open")
        $('#dialog').dialog("open");
    }
</script>

Answer 2:

如果你只是想访问内部jQuery的模型变量或ViewBag，你可以试试下面的方法。

<script type="text/javascript">

    function set(value) {
        return value;
    }

    alert(set(@Html.Raw(Json.Encode(Model.Message)))); // Message set from controller
    alert(set(@Html.Raw(Json.Encode(ViewBag.UrMessage))));

</script>

谢谢
