Question

我们希望在删除前显示警告用户的提示。目前我们正在尝试使用模态但我们无法访问项目ID，我们不知道如何将其传递给cshtml中的模态。

这就是我们如何显示我们想让用户删除的项目：

@foreach (var role in Model.AllRoles)
{
    <tr>
        <td>@role.Name</td>
        <td>
            <a asp-area="SysAdmin" asp-controller="Role" asp-action="EditRole" asp-route-id="@role.Id" class="btn btn-sm btn-success" style="width: 100%">Edit</a>
        </td>
        <td>
            <button type="submit" class="btn btn-sm btn-danger" data-toggle="modal" data-target="#deleteRoleModal" style="width: 100%">
                Delete
            </button>
        </td>
    </tr>
}

因此删除按钮会显示一个模态，目前看起来像这样：

<div class="modal fade" id="deleteRoleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <h5 class="modal-title" id="exampleModalLabel">Delete Role</h5>
                <button class="close" type="button" data-dismiss="modal" aria-label="Close">
                    <span aria-hidden="true">×</span>
                </button>
            </div>
            <div class="modal-body">Are you sure you want to delete this role?</div>
            <div class="modal-footer">
                <button class="btn btn-secondary" type="button" data-dismiss="modal">Cancel</button>
                <a class="btn btn-primary" asp-area="SysAdmin" asp-controller="Role" asp-action="DeleteRole">Delete Role</a>
            </div>
        </div>
    </div>
</div>

因此，当用户单击删除角色时，他们将在Controller角色上调用Action DeleteRole，后者将获取ID。但是，由于模式不知道要删除的对象的ID，我们无法将其传递给Action。

所以问题是我们如何将表中的ID发送到模态，以便在用户想要删除时将其传递给Action？

试试这个，

@foreach (var role in Model.AllRoles)
{
    <tr>
        <td>@role.Name </td>
        <td>
            <a asp-area="SysAdmin" asp-controller="Role" asp-action="EditRole" asp-route-id="@role.Id" class="btn btn-sm btn-success" style="width: 100%">Edit</a>
        </td>
        <td>
            <button onclick="SetId(@role.Id)" type="submit" class="btn btn-sm btn-danger" data-toggle="modal" data-target="#deleteRoleModal" style="width: 100%">
                Delete
            </button>
        </td>
    </tr>
}

模态

<div class="modal fade" id="deleteRoleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
    <div class="modal-dialog" role="document">
        <div class="modal-content">
            <div class="modal-header">
                <h5 class="modal-title" id="exampleModalLabel">Delete Role</h5>
                <button class="close" type="button" data-dismiss="modal" aria-label="Close">
                    <span aria-hidden="true">×</span>
                </button>
            </div>
            <div class="modal-body">Are you sure you want to delete this role?</div>
            <div class="modal-footer">
                <button class="btn btn-secondary" type="button" data-dismiss="modal">Cancel</button>
                <button onclick="DeleteRole" class="btn btn-primary">Delete Role</button>
            </div>
        </div>
    </div>
</div>

脚本标记

<script>

    var selectedId = 0;
    var deleteURL = '@Url.Action("DeleteRole", "Role", new { Area = "SysAdmin" })';
    SetId(id)
    {
        selectedId = id;
    }

    DeleteRole()
    { 

        if (selectedId !== 0)
        {
            deleteURL = deleteURL + "?id=" + selectedId;
            window.open(deleteURL,"_self")
        }
    }

</script>
