隐藏按钮和注释文本框... [英] Hide a button and Comments Text box...

问题描述

你好，

我是ASP.NET MVC框架的新手.

我正在创建一个像Facebook这样的小型网站.

我有注册表和登录功能.显示数据库中存在的所有朋友(用户)的功能.
我做了一个功能添加为朋友.哪个人可以用来与另一个指定的人成为朋友. IT工作正常..但我需要从正在登录的用户的用户中隐藏此添加人.

像.. 3个人在列表中.马丁，尤纳斯，米凯尔.如果martin登录到网站并且他只有Younas作为朋友，那么我希望Younas名称前面的添加"按钮是invisibel.

我该怎么做，希望你能理解??? (就像Facebook的禁友名单)

第二个我需要评论框，我们可以在其中添加赞或状态，例如facebook或twittter?

请帮助我.

Hello,

I''m new to ASP.NET MVC framework.

I''m creating a small webssite like Facebook.

I have registration form and login function. A function which shows all friends(users) who are exist in database.
I made a function Add as Friend. Which person can use to make the other specifik person as a friend. IT works fine.. but I need to hide this Add person from those person who are users of the person who are login.

How can I do that hope u understand ??? (Like facebook frined list)

2nd I need Comment box where we can add commens or status like facebook or twittter??

推荐答案

ASP.NET MVC，关键部分是 ASP.NET .如果要在页面(视图)上添加控件，请添加它.您到底有什么困难?

ASP.NET MVC, the key part is ASP.NET. If you want a control on the page (view) then add it. What part exactly are you having difficulty with?

如果有任何可能，我可以向您发送我的项目.它的make功能意味着我将visibel功能隐藏在什么地方以及我拥有什么编写功能.

Friendlist.cs
--------------
命名空间SocialNet.Domain.Entities
{
公共类FriendsList
{
私有列表< UserLine>行=新列表< UserLine>();
公共IList< UserLine>行{get {返回lines.AsReadOnly(); }}
公共无效AddItem(用户)

{
var line = lines
.FirstOrDefault(x => x.User.userID == user.userID);
如果(line == null)
lines.Add(new UserLine {User = user});
//else
//lines.Add(null);
}

}
公共类UserLine
{
公共用户用户{放; }
}
}

它的控制器:
................
公共类FriendsListController:控制器
{公共类FriendsListController:控制器
{
私有IUsersRepository usersRepository;
公共FriendsListController(IUsersRepository usersRepository)
{
this.usersRepository = usersRepository;
}
公共RedirectToRouteResult AddToFriendsList(FriendsList朋友列表，int userId，
字符串returnUrl)
{
用户用户= usersRepository.Users
.FirstOrDefault(p => p.userID == userId);
friendsList.AddItem(user);
return RedirectToAction("FriendsListPage"，new {returnUrl});
}
{
返回视图(新的FriendsListViewModel
{
FriendsList = friendsList，
ReturnUrl = returnUrl
});
}
}

好友列表视图

此视图以行显示朋友列表..并具有添加到列表中的按钮.

Friendlist.cs
--------------
namespace SocialNet.Domain.Entities
{
public class FriendsList
{
private List<UserLine> lines = new List<UserLine>();
public IList<UserLine> Lines { get { return lines.AsReadOnly(); } }
public void AddItem(User user)

{
var line = lines
.FirstOrDefault(x => x.User.userID == user.userID);
if (line == null)
lines.Add(new UserLine { User = user });
//else
//lines.Add(null);
}

}
public class UserLine
{
public User User { get; set; }
}
}

its controller:
................
public class FriendsListController : Controller
{public class FriendsListController : Controller
{
private IUsersRepository usersRepository;
public FriendsListController(IUsersRepository usersRepository)
{
this.usersRepository = usersRepository;
}
public RedirectToRouteResult AddToFriendsList (FriendsList friendsList, int userId,
string returnUrl)
{
User user = usersRepository.Users
.FirstOrDefault(p => p.userID == userId);
friendsList.AddItem(user);
return RedirectToAction("FriendsListPage", new { returnUrl });
}
{
return View(new FriendsListViewModel
{
FriendsList = friendsList,
ReturnUrl = returnUrl
});
}
}

friendlist view
---------------
]]>

using(Html.BeginForm("AddToFriendsList", "FriendsList")){ %>
<![CDATA[<%: Html.HiddenFor(x => x.userID) %>]]>

<![CDATA[<%: input type="submit"; value="Add as Friend" />
