如何将子局部视图添加到父局部视图？

Question

我有一个添加父局部视图的按钮，父局部视图也有一个添加按钮，它在其中添加子局部视图。我的问题是，当我按主按钮添加 2 个父局部视图并在第二个父视图中按添加子局部按钮时局部视图，然后在第一个父局部视图中创建子局部视图。我想根据父局部视图添加子局部视图。 我怎样才能做到这一点？

编码

//父部分

<div id="individual-details" class="card">
    <div class="card-header">
        @(Model.SearchFirstName + Model.SearchLastName == "" ? "New Search Individual" : Model.SearchFirstName + Model.SearchLastName)
        @if (ViewData["hideRemove"] == null || (bool?)ViewData["hideRemove"] == false)
        {
            <a id="individual-remove" href="#" onclick="removeIndividual(this)" class="btn btn-danger pull-right">Remove</a>
        }
    </div>
    <div class="form-horizontal">
        <div class="card-block">
            <div class="form-group">
                @Html.LabelFor(m => m.SearchPostcode, "Search Post Code", new { @class = "form-control-label" })
                @Html.TextBoxFor(m => m.SearchPostcode, null, new { @class = "form-control" })
            </div>

        </div>
    </div>
    <div class="card-block">
        <div id="Characteristics" class="mb-3">
            @if (Model?.Characteristics != null)
            {
                for (var i = 0; i < Model?.Characteristics.Count; i++)
                {
            <div class="form-group">
                @{ Html.RenderPartial("IndividualSearchCharacterisiticPartial", Model.Characteristics[i], new ViewDataDictionary()); }
              @*  @Html.EditorFor(m => m.Characteristics);*@
            </div>
                }
            }
        </div>
        <button id="add-characteristics" onclick="add(this)" type="button" class="btn btn-success">Add Characteristics</button>

</div>

//Button 
function add(element){
               var action = ' @Url.Action("NewIndividualSearchCharacteristic", "Blended")';
               $.post(action)

                  $('#Characteristics').append(partialView);
              });

Answer 1

$('#Characteristics').append(partialView);

如果您使用 Id 选择器，它将始终选择具有 id Characteristics的第一个元素。

试试下面的代码：

function add(element){
        var action = ' @Url.Action("NewIndividualSearchCharacteristic", "Blended")';
        $.post(action)
        .done(function (partialView) {
            element.previousElementSibling.append(partialView);
        });
}
