使用 Bootstrap Modal Confirmation 删除列表项

Question

我正在尝试使用引导模式创建删除确认。除了模态总是显示和删除列表中的第一项而不是单击删除按钮的实际列表项之外，一切都运行良好。有人可以看到我哪里出错了吗？

<table class="table">

@foreach (var item in Model)
{
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.InvoiceID)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Description)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.InvoiceDate)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.DueDate)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.Paid)
        </td>
        <td style="white-space: nowrap;width: 1px;">               
            <button type="button" class="btn btn-primary btn-xs" onclick="location.href='@Url.Action("Edit", "Billing", new { id = item.InvoiceID })'"><span class="glyphicon glyphicon-edit" style="vertical-align:middle;margin-top: -5px"></span> Edit</button>
            <button type="button" class="btn btn-default btn-xs" onclick="location.href='@Url.Action("Index", "InvoiceItem", new { id = item.InvoiceID })'"><span class="glyphicon glyphicon-eye-open" style="vertical-align:middle;margin-top: -5px"></span> Details</button>
            <button type="button" class="btn btn-danger btn-xs" data-toggle="modal" data-target="#myModal" data-id=@item.InvoiceID><span class="glyphicon glyphicon-trash" style="vertical-align:middle;margin-top: -5px"></span> Delete</button>
            <div id="myModal" class="modal fade" role="dialog">
                <div class="modal-dialog">
                    <!-- Modal content-->
                    <div class="modal-content">
                        <div class="modal-header">
                            <button type="button" class="close" data-dismiss="modal">&times;</button>
                            <h4 class="modal-title">Confirm Delete</h4>
                        </div>
                        <div class="modal-body">
                            <!-- The problem seems to be here:--> 
                            <p>Are you sure you want to delete invoice number: <b>@item.InvoiceID</b></p>
                        </div>
                        <div class="modal-footer">
                            <form asp-controller="Billing" asp-action="Delete" asp-route-id=@item.InvoiceID method="post" class="form-inline" role="form">
                                <button type="submit" class="btn btn-danger"><span class="glyphicon glyphicon-trash" style="vertical-align:middle;margin-top: -5px"></span> Delete</button>
                                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                            </form>
                        </div>
                    </div>
                </div>
            </div>               
        </td>
    </tr>
}

上面的视图是通过脚本加载的，以避免在更改下拉列表时使用以下代码刷新页面：

<script type="text/javascript">     


    $(document).ready(function () {
        loadPartial();
        $("#ddlCategory").change(loadPartial);
    });

    function loadPartial() {
        var companyID = $("#ddlCategory").val();
        var displayPaid = $("#chkDisplayPaid").is(':checked');
        var url = '@(Url.Action("InvoiceList", "Billing",null, null ))?companyID=' + companyID + '&displayPaid=' + displayPaid;
        $("#InvoiceList").load(url);
    }
</script>

您在循环中使用相同的 id 重复相同的模态，这是错误的，html 页面不能有重复的 id，要么将您的模态更改id="myModal"为id="@(i + 1)"anddata-target="#(i +1 )"并foreach循环以for循环为@for(var i = 0; i > model.count() ; i++).

但是这种方法是错误的，因为您要为每一行重复模态。

取而代之的是，将模态保持在表格之外并按如下方式进行：

@foreach (var item in Model)
{      
  ......rest same code                     
   <button type="button" class="btn btn-danger btn-xs" data-toggle="modal" data-target="#myModal" data-id=@item.InvoiceID><span class="glyphicon glyphicon-trash" style="vertical-align:middle;margin-top: -5px"></span> Delete</button>
  ....... rest same code     
 }

将您的模态从表格中取出并在其表单中添加带有 id 的输入隐藏字段。

<div id="myModal" class="modal fade" role="dialog">
                <div class="modal-dialog">
                    <!-- Modal content-->
                    <div class="modal-content">
                        <div class="modal-header">
                            <button type="button" class="close" data-dismiss="modal">&times;</button>
                            <h4 class="modal-title">Confirm Delete</h4>
                        </div>
                        <div class="modal-body">
                            <!-- The problem seems to be here:--> 
                            <p>Are you sure you want to delete invoice number: <b id="InvoiceID"></b></p>
                        </div>
                        <div class="modal-footer">
                            <form asp-controller="Billing" asp-action="Delete" method="post" class="form-inline" role="form">
<input type="hidden" id="id">
                                <button type="submit" class="btn btn-danger"><span class="glyphicon glyphicon-trash" style="vertical-align:middle;margin-top: -5px"></span> Delete</button>
                                <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
                            </form>
                        </div>
                    </div>
                </div>
            </div> 

show.bs.modal 事件在打开模态时触发。

 $(document).ready(function () {
        $('#myModal').on('show.bs.modal', function (event) {
            var button = $(event.relatedTarget);//Button which is clicked
            var clickedButtonId= button.data('Id');//Get id of the button
// set id to the hidden input field in the form.
           $("#InvoiceID").text(clickedButtonId);
           $("input #id").val(clickedButtonId);
    });    

*如果您愿意，对于编辑和详细信息，您可以在同一页面中打开相同或不同的模式。
