twitter-bootstrap - 用于删除确认 mvc 的 Bootstrap 模式

Question

我正在开发一个 MVC 5 Web 应用程序。在我的一个 Razor View 中，我有一个表格，它吐出几行数据。每行数据旁边是一个删除按钮。当用户单击删除按钮时，我希望弹出 Bootstrap 模式并要求用户确认删除。

在 foreach 循环之前添加一行

@Html.Hidden("item-to-delete", "", new {@id = "item-to-delete"})
@foreach (var item in Model)
{
    <td>
        <button type="" class="btn btn-sm blue deleteLead" 
            data-target="#basic" data-toggle="modal" 
            data-id="@item.bookid">delete</button>
    </td>
}

2.和我的模态

<div class="modal fade" id="basic" tabindex="-1" role="basic" aria-hidden="true" style="display: none;">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true"></button>
                <h4 class="modal-title">book Delete Confirmation</h4>
            </div>
            <div class="modal-body">
                Are you Sure!!! You want to delete this Ad?
            </div>
            <div class="modal-footer">
                <button type="button" class="btn blue" id="btnContinueDelete">Continue</button>
                <button type="button" class="btn default" data-dismiss="modal">Cancel</button>
            </div>
        </div>
    </div>
</div>

脚本

<script>
    $(".deletebook").click(function(e) {
        e.preventDefault();
        var id = $(this).data('id');
        $('#item-to-delete').val(id);
    });
    $('#btnContinueDelete').click(function() {
        var id = $('#item-to-delete').val();
        $.post(@Url.Action("Deletebook", "book"), { id: id }, function(data) {
            alert("data deleted");
        });
    });
</script> 

在控制台中我得到 =>
传递给 getElementById() 的空字符串。

警告，通过 GET 请求删除项目是不安全的!
最后我找到了一种使用 Bootstrap 模式对话框来确认删除列表项的方法:

<tbody>
    @foreach (var item in Model)
    {
        <tr>
            <td>
                <a id="deleteItem" class="deleteItem" data-target="#basic" 
                    data-toggle="modal" 
                    data-path="@Url.Action("Delete", "MyController", new { id = @item.id })">Delete</a>
            </td>
            <td>@Html.DisplayFor(modelItem => item.name)</td>
        </tr>
    }
</tbody>

这是我的模态 html

<div class="modal fade" id="basic" tabindex="-1" role="basic" aria-hidden="true" style="display: none;">
<div class="modal-dialog">
    <div class="modal-content">
        <div class="modal-header">
            <button type="button" class="close" data-dismiss="modal" aria-hidden="true"></button>
            <h4 class="modal-title">Delete Confirmation</h4>
        </div>
        <div class="modal-body">
            Are you sure you want to delete this item?
        </div>
        <div class="modal-footer">
            <button data-dismiss="modal" type="button" class="btn btn-default">Cancel</button>
            <button id="btnContinueDelete" type="button" class="btn btn-primary">Delete</button>
        </div>
    </div>
</div>

和 javascript 部分

<script>
    var path_to_delete;

    $(".deleteItem").click(function(e) {
        path_to_delete = $(this).data('path');
    });

    $('#btnContinueDelete').click(function () {
        window.location = path_to_delete;
    });
</script>

这是 Controller Action

// GET: MyController/Delete
[HttpGet]
public ActionResult Delete(int id)
{
    var model = Context.my_models.Where(x => x.id == id).FirstOrDefault();
    if (model != null)
    {
        Context.my_models.DeleteOnSubmit(model);
        Context.SubmitChanges();

        return RedirectToAction("List");
    }

    return new HttpNotFoundResult();
}
