Question

我正在使用 jquery 对话框来显示我添加和修改问题的视图的详细信息

我能够显示表单，并且在更新按钮上，第一级验证工作正常，[Required]和[RegularExpression(...)]，但它不适用于模型验证级别（{{1 }}，模型返回错误，但表单没有显示它们。

这是我正在使用的IValidatableObject

模型

 [HttpPost]
        public ActionResult _Degree(TDegree degree)
        {
            if (ModelState.IsValid)
            {
                if (degree.Degree == 0)
                {
                    db.TDegrees.Add(degree);
                    db.SaveChanges();
                }
                else
                {
                    TryUpdateModel<TDegree>(degree);
                }
                return RedirectToAction("Index", "Profile");
            }
            // what should i return here to stay on the dialog form + returning the errors? i tried this way to show the errors but the errors not shown as html but string
            return Content(ShowAllErrors());
        }
        private String ShowAllErrors()
        {
            StringBuilder sb = new StringBuilder();
            TagBuilder ul = new TagBuilder("ul");
            foreach (var e in ModelState.Values.Where(t => t.Errors.Count > 0))
            {
                foreach (var d in e.Errors)

如何让对话框中显示所有级别的验证？提前谢谢

在浪费了差不多2天后，我偶然发现了解决问题的方法。我用于partial / jquery对话框的框架与您使用的相同（我从博客文章中获取）。我修改了我的Create方法，如下所示：

[HttpPost]
public JsonResult Create(EventObject evt)
{
    if(ModelState.IsValid)
    {
        //save the model and return success
        return new JsonResult{
                                 Data = new
                                        {
                                            Result="S",
                                            Message="successfully created event"
                                        }
                            };
    }
    else
    {
        return new JsonResult{
                                Data = new
                                        {
                                            Result="E",
                                            Message=CONVERT MODELSTATE TO STRING
                                        }
                            };
    }
}

现在在标记方面，我有以下div：

<div id="create-event-error"></div>

我的更新功能如下：

function updateSuccess(a) {
    if (a.Result=="S") {
        $("#update-message").html(a.Message).show().delay(3000).hide();
        $dlg.dialog('close');
    }
    else {
         var d=$("div#create-event-errors");
         d.html(a.Message).dialog({
           //VARIOUS DIALOG OPTIONS
         });
    }
}

取代对话，您可以随意显示错误。
