在模态中加载模型只能工作一次

Question

我有这个烦人的问题，我一直在努力修复过去几晚。 到目前为止没有运气。 我有一个视图与模态和局部视图，呈现在模态中。 我在部分视图中填写了基于我在控制表中单击按钮时传递给控制器​​的参数的数据。 第一个很顺利，按钮调用控制器 - >控制器将模型传递给partialview - >模态打开，右侧数据在字段中。

当我单击另一条记录上的按钮时，将打开模态并显示旧数据。 未再次调用控制器，因此数据不会刷新。 问题是，如果我用shift + f5刷新页面，它会再次工作一次。 所以它似乎是一个缓存问题。

到目前为止我尝试过 - 在我的控制器和方法中禁用缓存 - 调用javascript方法从我的模态中删除数据 - 使用其他类型的模态

使用Javascript

<script>
$(function () {
    $('body').on('click', '.modal-link', function (e) {
        e.preventDefault();
        $(this).attr('data-target', '#modal-container');
        $(this).attr('data-toggle', 'modal');
    });

    $('body').on('click', '.modal-close-btn', function () {
        $('#modal-container').modal('hide');
    });

    debugger;
    $("#modal-container").on("hidden.bs.modal", function () {
        $(".modal-body").removeData();
    });
});

局部视图

        @using (Html.BeginForm("Create", "TripRegistration"))

                @Html.ValidationSummary(true)

控制器动作

        [NoCache]
    public PartialViewResult CopyTripRegistrationModal(int registrationId)
    {
        var tripRegistration = _tripRegistrationService.getTripRegistrationById(registrationId);
        var tripRegistrationVM = AutoMapper.Mapper.Map<tblTripRegistration, TripRegistrationViewModel>(tripRegistration);
        return PartialView("_CopyTripRegistration", tripRegistrationVM);        
    }

我已将“[OutputCache（Duration = 0）]”添加到控制器的顶部。

我希望有人可以帮助我！

您可以显式地进行ajax调用并将其响应设置为模态体。

$(function () {

     $('body').on('click', '.modal-link', function (e) {
         e.preventDefault();

         $("#modal-container").remove();
         $.get($(this).attr("href"), function (data) {
                 $('<div id="modal-container" class="modal fade">
                        <div class="modal-content" id="modalbody">' 
                                               + data + '</div></div>').modal();
         });
    });
});
