Question

我想在我的网站上添加产品。当我点击创建产品时，我必须输入一些值。尝试在没有任何数据的情况下进行保存时，您需要检查验证是否有效。它工作，但当我点击提交表格不是在模态弹出窗口（图像2） - 它显示像其他网站

我想要这样（image1） - 以模态弹出显示

以红色突出显示的验证是波兰语，但这意味着这些字段是必需的。

我使用formData，因为我必须发送一个文件。

modalform.js

var formdata = new FormData($('form').get(0));
    $('form', dialog).submit(function () {
        $.ajax({
            url: this.action,
            type: this.method,
            data: formdata,
            success: function (result) {
                if (result.success) {
                    $('#myModal').modal('hide');
                } else {
                    $('#myModalContent').html(result);
                    bindForm();
                }
            }
        });
        return false;
    });

我正在使用AJAX发布来提交表单中的数据。当使用$（this）.serialize（）时，正在调用ajax成功，但由于内容类型不同，文件未返回。我怎么能改变这个？

模型

public partial class Produkty
    {
        public int PRO_Id { get; set; }
        public string PRO_Nazwa { get; set; }
        public string PRO_Jednostka { get; set; }
        public float PRO_Vat { get; set; }
        public string PRO_Rodzaj { get; set; }
        public string PRO_Opis { get; set; }
        public string PRO_Waluta { get; set; }
        public float PRO_CenaN { get; set; }
        public float PRO_CenaB { get; set; }
        public string PRO_ZdjecieN { get; set; }
        public byte[] PRO_ZdjecieF { get; set; }
    }

请帮助解决这个问题。

Answer 1

在模型类中添加验证

public partial class Produkty
    {
        [Required(ErrorMessage = "*")]

        public int PRO_Id { get; set; }
        [Required(ErrorMessage = "*")]

        public string PRO_Nazwa { get; set; }
        public string PRO_Jednostka { get; set; }
        public float PRO_Vat { get; set; }
        public string PRO_Rodzaj { get; set; }
        public string PRO_Opis { get; set; }
        public string PRO_Waluta { get; set; }
        public float PRO_CenaN { get; set; }
        public float PRO_CenaB { get; set; }
        public string PRO_ZdjecieN { get; set; }
        public byte[] PRO_ZdjecieF { get; set; }
    }

在您的视图页面中添加此代码

   $('#form1').removeData('validator');
   $('#form1').removeData('unobtrusiveValidation');
   $.validator.unobtrusive.parse('#form1');
