Question

我有以下代码行，我需要该字段是强制性的，我已经把＃34;必需＆＃34;，但是在运行代码时，它不会使字段成为必填字段而只是允许该字段是空的，

@Html.AutocompleteFor(model => model.AgenteNaviero_Codigo, model => model.AgenteNaviero_Nombre, false, Url.Action("AutocompleteAgenteNavieroSearch", "AgenteNaviero", new { area = "Maestros", required = "required" }), "width: 80%")

我感谢你能帮助我或说我如何能让你把这个领域作为强制性的。

Answer 1

您是否尝试在模型上应用DataAnnotation？我认为你可以对你的模型属性做这样的事情

[Required]
AgenteNaviero_Codigo

然后在你的行动中，

public ActionResult AutocompleteAgenteNavieroSearch(YourModel model)
{
    if (ModelState.IsValid)
    {
         ...
    }

    return View(model);
}

例如，

 public class Movie
    {
        public int ID { get; set; }

        [Required(ErrorMessage = "Title is required")]
        public string Title { get; set; }

        public DateTime ReleaseDate { get; set; }

        [Required(ErrorMessage = "Genre must be specified")]
        public string Genre { get; set; }

        [Range(1, 100, ErrorMessage = "Price must be between $1 and $100")]
        public decimal Price { get; set; }

        [StringLength(5)]
        public string Rating { get; set; }
    }

<强>控制器

[HttpPost]
public ActionResult Create(Movie movie)
{
    if (ModelState.IsValid)
    {
        db.Movies.Add(movie);
        db.SaveChanges();
        return RedirectToAction("Index");
    }

    return View(movie);
}
