Question

我有一个显示数据的主表格。然后，我在每行上都有一个“评论”链接，单击该链接会打开带有表的局部视图。部分视图用于查看/添加注释和其他数据。在此局部视图中，在表格后面，有一些文本框可以填充数据。添加数据后，我单击“添加”，完成后，我将单击“保存”，然后将在文本框中键入的内容输入数据库。所有这些都有效，并且使您对我正在使用的东西有所了解（另请参见随附的图片）。

我现在正在寻找的一种方法是用“号码”字段中的号码（在主窗体上）填充“票号”文本框（在局部视图上）。另外，不应在局部上编辑该编号。我该如何实现？

我一直找不到解决方案。请帮忙。谢谢。

这是控制器中的代码：

    //VIEW ALL COMMENTS AND DISPLAY IN PARTIAL
    [HttpPost]
    public ActionResult ViewComments(int ticketNum)
    {
        List<Comment> AllComments = new List<Comment>();
        using (DBModel db = new DBModel())
            AllComments = db.Comments.Where(x => x.TicketNumber == ticketNum).ToList();

        return PartialView("ViewComments", AllComments);
    }


    //INSERT COMMENT
    public JsonResult InsertComments(List<Comment> commentsArray)
    {
        using (DBModel db = new DBModel())
        {
            //Truncate Table to delete all comments. Previous comments are copied in javascript and re-populated
            db.Database.ExecuteSqlCommand("TRUNCATE TABLE [Comments]");

            //Check for NULL
            if (commentsArray == null)
            {
                commentsArray = new List<Comment>();
            }

            foreach (Comment comment in commentsArray)
            {
                db.Comments.Add(comment);
            }               
            int insertedRecords = db.SaveChanges();
            return Json(insertedRecords);
        }
    }

这是从主视图显示部分视图的方式：

    @section modalComments
{
<script type="text/javascript">
    function showComments() {
        $("#dialog").dialog({
            autoOpen: false,
            modal: true,
            title: "View Details"
        });
        $("#ticketTable .details").click(function () {
            var ticketNum = $(this).closest("tr").find("td").eq(0).html();
            $.ajax({
                type: "POST",
                url: "/Tickets/ViewComments",
                data: '{ticketNum: "' + ticketNum + '" }',
                contentType: "application/json; charset=utf-8",
                dataType: "html",
                success: function (response) {
                    $('#dialog').html(response);
                    $('#dialog').dialog('open');
                },
                failure: function (response) {
                    alert(response.responseText);
                },
                error: function (response) {
                    alert(response.responseText);
                }
            });
        });
    };

    $(function () {
        showComments();
    });
</script>

}

这是部分视图：

    @model IEnumerable<HelpDeskSupport.Models.Comment>

    <html>
    <body>
    <table class="table table-striped table-bordered" cellpadding="0" cellspacing="0" border="0" width="1500" id="tblComments">
    <thead>
        <tr>
            <th>
                @Html.DisplayNameFor(model => model.TicketNumber)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.Comment1)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.AssignedTo)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.CreatedBy)
            </th>
            <th>
                @Html.DisplayNameFor(model => model.Date)
            </th>
        </tr>
    </thead>
    <tbody>
        @foreach (var item in Model)
        {
            <tr>

                </td>
                <td>
                    @Html.DisplayFor(modelItem => item.AssignedTo)

这可以通过使用以下代码行解决：

    <td><input type="text" id="txtTicketNumber" value=@ViewData["NumberFromViewAll"] readonly /></td>

从表单元格获取值并在MVC的部分视图表单元格中显示
