我Ajax形式得到正确Id更新内容和replace选项。 提交是需要点击<input type="submit" value="submit!" />。
Problem：当我点击submit我没有看到任何更新。第二次审判给出了预期的结果。当我刷新页面时，失去的记录（第一次成功）就在现场。
模型
[Serializable]
public abstract class AbstractEntity {
public Guid Id { get; set; }
public DateTime LastModified { get; set; }
}
[Serializable]
public class Product : AbstractEntity {
public Product() {
this.Attachments = new HashSet<Attachment>();
}
public String Title { get; set; }
public String Commentary { get; set; }
public DateTime PlacedOn { get; set; }
public String User { get; set; }
public ICollection<Attachment> Attachments { get; set; }
}
[Serializable]
public class Attachment {
public String MimeType { get; set; }
public String Description { get; set; }
public String Filename { get; set; }
}
控制器
[HandleError]
public class ProductController : Controller {
private readonly IDocumentSession documentSession;
public ProductController(IDocumentSession documentSession) {
this.documentSession = documentSession;
}
public ActionResult ListRecent() {
return View(ListAll());
}
[Audit, HttpPost]
public ActionResult Delete(Guid id) {
documentSession.Delete<Product>(documentSession.Load<Product>(id));
documentSession.SaveChanges();
return PartialView("ProductsList", ListAll());
}
[Audit, HttpPost]
public ActionResult Create(Product product) {
if(ModelState.IsValid) {
documentSession.Store(product);
documentSession.SaveChanges();
}
return PartialView("ProductsList", ListAll());
}
private IEnumerable<Product> ListAll() {
return documentSession.Query<Product>().ToArray();
}
}

您是否包含了不显眼的ajax库？ – VJAI
你能展示你的视图代码吗？ –
你在哪里包含'jquery.unobtrusive-ajax.js'脚本？我无法在任何地方看到它。它是否在你的布局？ –
