用确认对话框删除 ActionLink

我正在尝试实现一个简单的 ActionLink，它将使用 ASP.NET MVC 删除记录。以下是我目前掌握的情况:

<%= Html.ActionLink("Delete",
"Delete",
new { id = item.storyId,
onclick = "return confirm('Are you sure?');"
})%>

但是，它没有显示确认框。显然我遗漏了什么，或者我错误地建立了链接。有人能帮忙吗？

those are routes you're passing in

<%= Html.ActionLink("Delete", "Delete",
new { id = item.storyId },
new { onclick = "return confirm('Are you sure you wish to delete this article?');" })     %>

The overloaded method you're looking for is this one:

public static MvcHtmlString ActionLink(
this HtmlHelper htmlHelper,
string linkText,
string actionName,
Object routeValues,
Object htmlAttributes
)

最佳答案

Don't confuse routeValues with htmlAttributes. You probably want this overload:

<%= Html.ActionLink(
"Delete",
"Delete",
new { id = item.storyId },
new { onclick = "return confirm('Are you sure you wish to delete this article?');" })
%>
小开 
<%= Html.ActionLink("Delete", "Delete",
new { id = item.storyId },
new { onclick = "return confirm('Are you sure you wish to delete this article?');" })     %>

The above code only works for Html.ActionLink.

For

Ajax.ActionLink

use the following code:

<%= 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" })%>

The 'Confirm' option specifies javascript confirm box.

You can also try this for Html.ActionLink DeleteId

You can also customize the by passing the delete item along with the message. In my case using MVC and Razor, so I could do this:

@Html.ActionLink("Delete",
"DeleteTag", new { id = t.IDTag },
new { onclick = "return confirm('Do you really want to delete the tag " + @t.Tag + "?')" })

Try this :

<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>

With image and confirmation on delete, which works on mozilla firefox

<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>

Using webgrid you can found it here, the action links could look like the following.

enter image description here 

    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()
)

Any click event before for update /edit/delete records message box alerts the user and if "Ok" proceed for the action else "cancel" remain unchanged. For this code no need to right separate java script code. it works for me

<a asp-action="Delete" asp-route-ID="@Item.ArtistID" onclick = "return confirm('Are you sure you wish to remove this Artist?');">Delete</a>

enter image description here MVC5 with delete dialogue & glyphicon. May work previous versions.

@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()))

I wanted the same thing; a delete button on my Details view. I eventually realised I needed to post from that view:

@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?');" />
}

And, in the Controller:

 // 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
