我想在局部视图中自动生成一个列表.

_Layout.cshtml

@ Html.Partial( “../交易/ _Transaction”)

TransactionController

public JsonResult transactionlist()
        {
            List<Transaction> TransactionList = new List<Transaction>().ToList();
            string Usercache = MemoryCache.Default[User.Identity.Name] as string;

            int UsercacheID = Convert.ToInt32(Usercache);
            if (Usercache == null)
            {
                int UserID = (from a in db.UserProfiles
                              where a.UserName == User.Identity.Name
                              select a.UserId).First();
                UsercacheID = UserID;
                MemoryCache.Default[User.Identity.Name] = UsercacheID.ToString();
            }
            var Account = (from a in db.UserAccount
                           where a.UserId == UsercacheID
                           select a).First();

            var DBTransaction = from a in db.Transaction
                                where a.AccountId == Account.AccountId
                                select a;

            var DBTransactionList = DBTransaction.ToList();
            for (int i = 0; i < DBTransactionList.Count; i++)
            {
                TransactionList.Add(DBTransactionList[i]);
            }
            ViewBag.acountsaldo = Account.Amount;

            return Json(TransactionList,JsonRequestBehavior.AllowGet);
        }`

如何编写_Transaction.cshtml来制作一个没有提交按钮等的简单列表？

解决方法

一种方法是让页面返回一个项目列表并将它们提供给您的部分.

function ActionResult GetMainTransactionView()
{
  List<Transaction> transactions=GetTransactions();
  return PartialView("TransactionIndex",transactions);
}

TransactionIndex.cshtml

@model List<Transaction>
@Html.Partial("../Transaction/_Transaction",model)

Main.chtml

<a id="transactionLink" href='@Url.Action("GetMainTransactionView","Transaction")'/>
