ASP.NET MVC删除操作链接确认

<td>
  <%= Html.ActionLink("Delete","DeleteUser",new RouteValueDictionary(new {uname=item.UserName}),new { onclick = "return confirm('Are you sure you want to delete this User?');" }) %>
    </td>

在Global.asax.cs

routes.MapRoute(
               "DeleteUser","Account.aspx/DeleteUser/{uname}",new { controller = "Account",action = "DeleteUser",uname = "" }
           );

在ActionContorller.cs

public ActionResult DeleteUser(string uname)
{
   //delete user
}

控制器中uname的值正在传递为空字符串(“”).

解决方法

<%= Html.ActionLink(
    "Delete","Account",new { 
        uname = item.UserName 
    },new { 
        onclick = "return confirm('Are you sure you want to delete this User?');" 
    }
) %>

然后确保生成的链接正确：

<a href="/Account.aspx/DeleteUser/foo" onclick="return confirm(&#39;Are you sure you want to delete this User?&#39;);">Delete</a>

另请注意,不推荐使用纯GET动词来修改服务器上的状态.

这是我会推荐你的：

[HttpDelete]
public ActionResult DeleteUser(string uname)
{
   //delete user
}

并认为：

<% using (Html.BeginForm(
    "DeleteUser",new { uname = item.UserName },FormMethod.Post,new { id = "myform" })
) { %>
    <%= Html.HttpMethodOverride(HttpVerbs.Delete) %>
    <input type="submit" value="Delete" />
<% } %>

并在一个单独的javascript文件中：

$(function() {
    $('#myform').submit(function() {
        return confirm('Are you sure you want to delete this User?');
    });
});

您也可以考虑添加一个anti forgery token来保护此操作免于CSRF attacks.
