Modal中的AddModelError

Question

我遇到了与这些人相同的问题，postback（AddModelError）出现在没有css的主屏幕中，而不是在模态弹出窗口中，这里有问题......

Twitter Bootstrap modal does not work properly when implementing in asp.net mvc

MVC 4: Return partial view inside of bootstrap modal upon failed validation

我已尝试按照与所述解决方案相同的步骤进行操作，但回发仍在主屏幕上（索引）

我没有看到什么是错的，我想知道我的代码有什么问题。

谢谢。

Answer 1

我按照解决方案提供给Stephen Muecke Remote验证

模特

[Required]
[DataType(DataType.EmailAddress)]
[Remote("isEmail_Available", "Agency")]
[StringLength(150)]
[Display(Name = "Correo Electronico")]
public string Email { get; set; }

控制器

public JsonResult isEmail_Available(string Email)
{
    var checkEmail = db.SystemUser.AsNoTracking().Where(u => u.Email == Email).FirstOrDefault();
    if (checkEmail == null)
        return Json(true, JsonRequestBehavior.AllowGet);

    string suggestedEmail = String.Format("{0} ya registrado.", Email);

    return Json(suggestedEmail, JsonRequestBehavior.AllowGet);
}
