<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
尝试这样：
<%= Html.ActionLink(
"Delete","Account",new {
uname = item.UserName
},new {
onclick = "return confirm('Are you sure you want to delete this User?');"
}
) %>
<a href="/Account.aspx/DeleteUser/foo" onclick="return confirm('Are you sure you want to delete this User?');">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.
