基于bool动态添加TextBox

Question

Case是一个MVC 5应用程序

我有一个班级（运动队），看起来像这样：

public class Team
    {
        public int Id { get; set; }
        public string TeamName { get; set; }
        public string Badge { get; set; }
        public TeamColor? TeamColor { get; set; }
        public League? League { get; set; }
        public bool HasAlias { get; set; }
        public bool IsAlias { get; set; }
        public int? AliasId { get; set; }
        public virtual Team AliasTeam { get; set; }
        public virtual ICollection<Team> Aliases  { get; set; }
    }

AliasTeam是一个只有TeamName和AliasId的团队。

如果用户单击原始团队中的HasAlias复选框，如何添加用于归档AliasTeamName的文本框？如何在控制器中循环文本框以将其添加为具有AliasId的团队原来的团队？

控制器操作现在看起来像这样，我可以添加一个团队

 public ActionResult CreateTeam(CreateTeamViewModel model)
        {
            if (ModelState.IsValid)
            {
                var team = new Team
                {
                    TeamName = model.TeamName,
                    TeamColor = model.TeamColor,
                    League = model.League
                };
                db.Teams.Add(team);
                db.SaveChanges();
                return RedirectToAction("AddTeamImage", new {teamid = team.Id});
            }

            return View(model);
        }

编辑：

通过添加以下js来解决它：

$(document).ready(function() {
        $("#HasAlias").change(function () {
            if (this.checked) {
                $(".textboxes").append('<div><input class="form-control text-box single-line" placeholder="enter aliasname" type="text" name="teams"/><a href="#" class="add_field"> <span class=" glyphicon glyphicon-plus-sign"></span></a><a href="#" class="remove_field"> <span class=" glyphicon glyphicon-minus-sign"></span></a></div>');
            } else {
                $(".textboxes").empty();
            }
        });
            $('.textboxes').on("click", ".add_field", function(e) {
                e.preventDefault();
                $(".textboxes").append('<div><input class="form-control text-box single-line" placeholder="enter aliasname" type="text" name="teams"/><a href="#" class="add_field"> <span class=" glyphicon glyphicon-plus-sign"></span></a><a href="#" class="remove_field"> <span class=" glyphicon glyphicon-minus-sign"></span></a></div>');
            });
            $('.textboxes').on("click", ".remove_field", function (e) {
                e.preventDefault(); $(this).parent('div').remove();
            });
        });

然后在Action中循环遍历各个团队：

public ActionResult CreateTeam(CreateTeamViewModel model, string[] teams)
        {
            if (ModelState.IsValid)
            {
                var team = new Team
                {
                    TeamName = model.TeamName,
                    TeamColor = model.TeamColor,
                    League = model.League,
                    HasAlias = model.HasAlias
                };
                db.Teams.Add(team);
                db.SaveChanges();
                foreach (var s in teams)
                {
                    var t = new Team
                    {
                        TeamName = s,
                        AliasId = team.Id,
                        IsAlias = true
                    };
                    db.Teams.Add(t);
                    db.SaveChanges();
                }


                return RedirectToAction("Index");
            }

            return View(model);
        }

我可能误解了整个ViewModel范例。我认为你创建ViewModel的意义在于，只需要创建结果所需的信息。
