Question

在我的项目中使用了ASP.NET MVC 5.我已经使用System.ComponentModel.DataAnnotations进行验证。我希望当我没有为必填字段输入值时，请阻止继续我的操作。但这种期望并不能令人满意。我该如何解决这个问题？

@model Jahan.Blog.ViewModel.ArticleViewModel

@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
<div class="form-horizontal">
    <h4>Article</h4>
    <hr />
    @Html.ValidationSummary(true)
    @Html.HiddenFor(model => model.UserId)

    @*There are some codes*@

    <div class="form-group">
        @Html.LabelFor(model => model.Title, htmlAttributes: new { @class = "control-label col-md-2" })
        <div class="col-md-10">
            @Html.EditorFor(model => model.Title)
            @Html.ValidationMessageFor(model => model.Title)
        </div>
    </div>

    @*There are some codes*@

   <div class="form-group">
        <div class="col-md-offset-2 col-md-10">
            <input type="submit" value="Save" class="btn btn-default" />
        </div>
    </div>
   </div>
}

视图模型：

[ModelBinder(typeof(ArticleViewModelBinder))]
public class ArticleViewModel : IArticleViewModel
{
    public ArticleViewModel()
    {

    }
    public virtual int Id { get; set; }
    [Required]
    [StringLength(256)]
    public virtual string Title { get; set; }
}

控制器：

    [AcceptVerbs(HttpVerbs.Post)]
    [ValidateAntiForgeryToken]
    public ActionResult Edit([Bind(Prefix = "")]ArticleViewModel articleViewModel, List<int> availableTags)
    {
        if (ModelState.IsValid)
        {
            // There are some codes.
        }
        return View(articleViewModel);
    }

Answer 1

打开 web.config ，在ClientValidationEnabled中找到appSettings，然后检查它是否设置为true：

<add key="ClientValidationEnabled" value="true" />

Answer 2

根据Fiskeboss的评论，jquery.validate.unobtrusive.js库已添加。然后才能正常使用。

客户端验证不起作用
