我正在尝试实现一个简单的ActionLink，用于使用ASP.NET MVC删除记录。目前为止，这是我的代码：
<%= Html.ActionLink("Delete",
"Delete",
new { id = item.storyId,
onclick = "return confirm('Are you sure?');"
})%>
然而，它没有显示确认框。显然我漏掉了一些东西或者链接构造不正确。有人能帮忙吗？
不要混淆routeValues和htmlAttributes。你可能需要使用这个重载：
<%= Html.ActionLink(
"Delete",
"Delete",
new { id = item.storyId },
new { onclick = "return confirm('Are you sure you wish to delete this article?');" })
%>
这些是你传递进去的路由
<%= Html.ActionLink("Delete", "Delete",
new { id = item.storyId },
new { onclick = "return confirm('Are you sure you wish to delete this article?');" }) %>
你所寻找的重载方法是这个：
public static MvcHtmlString ActionLink(
this HtmlHelper htmlHelper,
string linkText,
string actionName,
Object routeValues,
Object htmlAttributes
)
<%= Html.ActionLink("Delete", "Delete",
new { id = item.storyId },
new { onclick = "return confirm('Are you sure you wish to delete this article?');" }) %>
以上代码仅适用于 Html.ActionLink。
对于
Ajax.ActionLink
请使用以下代码：
<%= Ajax.ActionLink(" ", "deleteMeeting", new { id = Model.eventID, subid = subItem.ID, fordate = forDate, forslot = forslot }, new AjaxOptions
{
Confirm = "Are you sure you wish to delete?",
UpdateTargetId = "Appointments",
HttpMethod = "Get",
InsertionMode = InsertionMode.Replace,
LoadingElementId = "div_loading"
}, new { @class = "DeleteApointmentsforevent" })%>
'确认'选项指定JavaScript确认框。
@Html.ActionLink("Delete",
"DeleteTag", new { id = t.IDTag },
new { onclick = "return confirm('Do you really want to delete the tag " + @t.Tag + "?')" })
尝试这个：
<button> @Html.ActionLink(" ", "DeletePhoto", "PhotoAndVideo", new { id = item.Id }, new { @class = "modal-link1", @OnClick = "return confirm('Are you sure you to delete this Record?');" })</button>
grid.Column(header: "Action", format: (item) => new HtmlString(
Html.ActionLink(" ", "Details", new { Id = item.Id }, new { @class = "glyphicon glyphicon-info-sign" }).ToString() + " | " +
Html.ActionLink(" ", "Edit", new { Id = item.Id }, new { @class = "glyphicon glyphicon-edit" }).ToString() + " | " +
Html.ActionLink(" ", "Delete", new { Id = item.Id }, new { onclick = "return confirm('Are you sure you wish to delete this property?');", @class = "glyphicon glyphicon-trash" }).ToString()
)
带有图片和确认删除功能，在Mozilla Firefox上可用。
<button> @Html.ActionLink(" ", "action", "controller", new { id = item.Id }, new { @class = "modal-link1", @OnClick = "return confirm('Are you sure you to delete this Record?');" })</button>
<style>
a.modal-link{ background: URL(../../../../Content/Images/Delete.png) no-repeat center;
display: block;
height: 15px;
width: 15px;
}
</style>
我也希望能在我的详细视图上有一个删除按钮。最终我意识到需要从该视图中进行发布：
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
@Html.HiddenFor(model => model.Id)
@Html.ActionLink("Edit", "Edit", new { id = Model.Id }, new { @class = "btn btn-primary", @style="margin-right:30px" })
<input type="submit" value="Delete" class="btn btn-danger" onclick="return confirm('Are you sure you want to delete this record?');" />
}
而在控制器中：
// this action deletes record - called from the Delete button on Details view
[HttpPost]
public ActionResult Details(MainPlus mainPlus)
{
if (mainPlus != null)
{
try
{
using (IDbConnection db = new SqlConnection(PCALConn))
{
var result = db.Execute("DELETE PCAL.Main WHERE Id = @Id", new { Id = mainPlus.Id });
}
return RedirectToAction("Calls");
} etc
MVC5 带有删除对话框和 glyphicon。可能适用于早期版本。
@Html.Raw(HttpUtility.HtmlDecode(@Html.ActionLink(" ", "Action", "Controller", new { id = model.id }, new { @class = "glyphicon glyphicon-trash", @OnClick = "return confirm('Are you sure you to delete this Record?');" }).ToHtmlString()))
在更新/编辑/删除记录之前的任何单击事件都会向用户发出消息框警报，如果选择“确定”，则继续执行该操作，否则保持不变。对于这个代码，不需要编写单独的JavaScript代码，它适用于我。
<a asp-action="Delete" asp-route-ID="@Item.ArtistID" onclick = "return confirm('您确定要删除此艺术家吗？');">删除</a>
