我正在使用MVC 4和Entity Framework来开发一个Web应用程序.我正在使用加载了javascript的部分视图.其中之一是包含验证的创建视图.这就是我的问题：验证.我有一个自定义验证逻辑,例如,如果用户在某个字段(如“名称”)中输入某些数字,则会显示错误.
在这里,使用部分视图,它将我的部分视图重定向到显示的错误,但我想要做的是保持在我的主视图(索引视图)并保留显示错误的部分视图.
编辑：
这是我的部分观点：
@model BuSIMaterial.Models.Person
@using (Html.BeginForm()) {
@Html.ValidationSummary(true)
BoxFor(model => model.FirstName,new { maxlength = 50 })
@Html.ValidationMessageFor(model => model.FirstName)
BoxFor(model => model.LastName,new { maxlength = 50 })
@Html.ValidationMessageFor(model => model.LastName)
BoxFor(model => model.NumNat,new { maxlength = 11 })
@Html.ValidationMessageFor(model => model.NumNat)
BoxFor(model => model.StartDate,new {@class = "datepicker",@placeholder="yyyy/mm/dd"})
@Html.ValidationMessageFor(model => model.StartDate)
BoxFor(model => model.EndDate,new { @class = "datepicker",@placeholder = "yyyy/mm/dd" })
@Html.ValidationMessageFor(model => model.EndDate)
在我看来,索引,我有这个：
以及我加载部分视图的方式：
$("#create").click(function () {
var form = $("#create_person").closest("form");
form.removeData('validator');
form.removeData('unobtrusiveValidation');
$.validator.unobtrusive.parse(form);
$.ajax({
url: "/Person/CreateOrUpdate",type: "POST",data: $("#create_person").serialize(),cache: false
});
// var url = '/Person/CreatePerson';
// $("#create_person").load(url);
});
行动 ：
[HttpGet]
public ActionResult CreateOrUpdate()
{
ViewBag.Id_ProductPackageCategory = new SelectList(db.ProductPackageCategories,"Id_ProductPackageCategory","Name");
return View();
}
[HttpPost]
public JsonResult CreateOrUpdate(Person person)
{
ViewBag.Id_ProductPackageCategory = new SelectList(db.ProductPackageCategories,"Name",person.Id_ProductPackageCategory);
try
{
if (!ModelState.IsValid)
{
string messages = string.Join("; ",ModelState.Values
.SelectMany(x => x.Errors)
.Select(x => x.ErrorMessage));
throw new Exception("Please correct the following errors: " + Environment.NewLine + messages);
}
db.Persons.AddObject(person);
db.SaveChanges();
return Json(new { Result = "OK" });
}
catch (Exception ex)
{
return Json(new { Result = "ERROR",Message = ex.Message });
}
}
最佳答案
如果您发布页面,它将不会返回到动态加载的局部视图.尝试对/ Person / CreatePerson进行ajax调用.您的CreatePerson看起来类似于
[HttpPost]
public JsonResult CreatePerson(Person person)
{
ViewBag.Id_ProductPackageCategory = new SelectList(db.ProductPackageCategories,person.Id_ProductPackageCategory);
try
{
if (!ModelState.IsValid)
{
string messages = string.Join("; ",ModelState.Values
.SelectMany(x => x.Errors)
.Select(x => x.ErrorMessage));
throw new Exception("Please correct the following errors: " + Environment.NewLine + messages);
}
db.Persons.AddObject(person);
db.SaveChanges();
return Json(new { Result = "OK" });
}
catch (Exception ex)
{
return Json(new { Result = "ERROR",Message = ex.Message });
}
} `
The ajax call to /Person/CreatePerson will look similar to
`
$.ajax({
url: '/Person/CreatePerson',data: $("#form").serialize(),success: function (responce) {
alert(responce.Message);
},error: function (xhr,textStatus) {
alert(xhr.status + " " + xhr.statusText);
}
});
除了不显眼的验证,动态内容也无法轻松完成.检查链接unobtrusive validation on dynamically added partial view (not working)
