我有以下观点：

@model GRCWebApp.ViewModels.NewClubInterestsViewModel

@{
ViewBag.Title = "Add Club Interests";
}
<div class="col-md-10 col-offset-md-1">
<h2 class ="text-success">Add Club Interests for @Html.DisplayFor(model => model.Name)</h2>
</div>

@using (Html.BeginForm("NewInterests", "Club", FormMethod.Post))
{
@Html.AntiForgeryToken()

<div class="form-horizontal">
    <hr />
    <div class="row">
        <div class="col-md-8">
            <div class="well bs-component">

                <div class="form-group">

                </div>
                <div class="col-md-offset-1">


                    @for (int i = 0; i < Model.ClubTypeInterests.Count();  i++)

                            @Html.CheckBoxFor(x => Model.ClubTypeInterests[i].selected)
                            @Html.LabelFor(x => Model.ClubTypeInterests[i].InterestName, Model.ClubTypeInterests[i].InterestName)
                        </div>

}

@using (Html.BeginForm("AddInterest", "Club"))
{
@Html.AntiForgeryToken()

                    </div>
                </div>
            </div>
        </div>
    </div>
</div>
}


@section Scripts {
@Scripts.Render("~/bundles/jqueryval")
}

超时页面加载第二种形式AddInterest中的InterestName的验证消息显示。

整个表单的Get方法是：

        [HttpGet]
    public ActionResult NewInterests(NewClubInterestsViewModel model, int id)
    {
        //Find the Club and then pass its id to the ViewModel
        var club = db.Clubs.Find(id);
        //model.ClubId = club.ClubId ;
        //Interests List         
        IEnumerable<Interest> allExistingInterests;
        //Generate a list of the interests that apply to that type of club
        using (ApplicationDbContext context = new ApplicationDbContext())
        {
            allExistingInterests = context.Interests
                .Where(s => s.ClubTypeId == club.ClubTypeId)
                .OrderBy(s => s.InterestName)
                .ToList();
        }
        IEnumerable<int> clubInterestIds = club.ClubInterests.Select(x => x.InterestId).ToList();
        //Generate the ViewModel with the appropriate Interests
        var viewModel = new NewClubInterestsViewModel
        {
            ClubId = club.ClubId,
            Name = club.Name,
            ClubTypeId = club.ClubTypeId,
            ClubTypeInterests =
                allExistingInterests.Select(
                    x => new ClubInterestsViewModel { InterestId = x.InterestId, InterestName = x.InterestName, selected = clubInterestIds.Contains(x.InterestId) }).ToArray()
        };
        return View(viewModel);
    }

如何停止在加载时显示验证消息，我需要做什么？

Answer 1

从GET方法中删除NewClubInterestsViewModel model参数。它应该只是

public ActionResult NewInterests(int id)

模型绑定过程的第一步是初始化参数的实例，然后根据表单值，路由值，查询字符串值等设置其属性。在您的情况下，没有要设置的值，因此模型的属性是它们的默认值，但由于您的属性上有验证属性，验证失败并且错误被添加到ModelState，然后显示在视图中。

JQuery验证消息显示在页面加载上
