如何使用 Ajax 将参数传递给模态表单

Question

我有一个显示所选报告的费用列表的剃须刀页面。 我在页面上有一个“添加费用”按钮，可以显示一个模式。 模态是表单的局部视图。 我需要做的是将 ExpenseId 传递给模态。 我可以像这样从 url 获取 Id

 @{ var expenseId = Request.Url.Segments[3]; }

该按钮目前看起来像这样

<button type="button" data-toggle="modal" data-target="#expenseModal_@expenseId" data-id="@expenseId" class="btn btn-primary" id="addExpenses">
                        Add Expense
                    </button>

这里面有一些东西我不知道我是否需要它们。 我在尝试不同的东西。

模态

<!-- MODAL -->
<div class="modal fade" id="expenseModal_@expenseId" tabindex="-1" role="dialog" aria-labelledby="expenseModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
    <div class="modal-content">
        <div class="modal-header">
            <h4 class="modal-title" id="expenseModalLabel"> Expences </h4>
            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
                <span aria-hidden="true">&times;</span>
            </button>
        </div> <!-- MODEL HEADER-->
        <div class="modal-body">
        </div> <!-- MODAL BODY-->
    </div>
</div>

Javascript

    <script type="text/javascript">
    $(document).ready(function () {
        $("#addExpenses").click(function () {

            $(".modal-body").html('');

            $.ajax({

                type: 'GET',
                url: '@Url.Action("_ExpenseForm", "Admin")',
                data: { type: $(this).attr("data-type") },
                success: function (response) {
                    $(".modal-body").html(response);
                    $("#expenseModal").modal('show');
                },
                error: function () {
                    alert("Something went wrong");
                }

            });

        });
    });
</script>

必须在表单中插入费用 ID，以便在保存时将其保存到正确的费用报告中。

控制器动作

    ExpensesDataAcessLayer objexpense = new ExpensesDataAcessLayer();
    public ActionResult ExpenseReports()
    {
        return View(db.ExpenseReports.ToList());
    }

    public ActionResult Expenses(int ExpenseId)
    {
        return View(db.Expenses.Where(x => x.ExpenseId == ExpenseId).ToList());
    }

    public ActionResult _ExpenseForm()
    {
        CustomerEntities customerEntities = new CustomerEntities();
        List<SelectListItem> categoryItem = new List<SelectListItem>();
        ExpensesViewModel casModel = new ExpensesViewModel();
        List<ExpenseTypes> expensetypes = customerEntities.ExpenseType.ToList();
        expensetypes.ForEach(x =>
        {
            categoryItem.Add(new SelectListItem { Text = x.CategoryItem, Value = x.ItemCategoryId.ToString() });
        });
        casModel.ExpenseTypes = categoryItem;

        return View(casModel);
    }

谢谢你的帮助！

Answer 1

您可以将expenseId存储到隐藏字段中，如下所示

<input id="expenseId" name="expenseId" type="hidden" value="@Request.Url.Segments[3]">

然后你可以像这样

 $("#addExpenses").click(function () {
var expenseId = $("#expenseId").val();
// after code here

更新

您可以像这样获得expenseId

var expenseId = $(this).attr("data-id")

然后你可以将它分配给隐藏字段或Model任何地方，像这样

<!-adding aditional input into HTML in MODEL-!>
<input id="expenseId" name="expenseId" type="hidden" value="">

<!- Javascript-!>
var expenseId = $(this).attr("data-id")
expenseId.val(expenseId );
