Angular Js web应用程序数据绑定无法从Sql数据库捕获数据

问题描述 投票:1回答:1

我正在使用wcf rest服务到angular js application.I我试图通过Wcf Rest Service显示来自sql数据库的数据。我正在使用Union函数来连接多表记录。我想将帐户信息显示到网页中,当我将帐户输入到输入字段并单击提交按钮但问题是它不是所需的数据..

这是班级。

public class AccountTransaction
    {
        public int? Account_Number { get; set; }

        public decimal? Deposit { get; set; }

        public decimal? Withdrawal { get; set; }

        public decimal? Account_Balance { get; set; }
        public string  Account_Type { get; set; }
        public string Account_Holder_Tittle { get; set; }
        public string Account_Holder_FirstName { get; set; }
        public string Account_Holder_LastName { get; set; }
        public string Date { get; set; }

    }

这是方法实现。

 public string AccountDetails(string Account_Number)
        {
            var accountNumber = int.Parse(Account_Number);//It could be better to use TryParse
            using (HalifaxDatabaseEntities context = new HalifaxDatabaseEntities())
            {
                var inOut = context.Current_Account_Deposit.Where(x => x.Account_Number == accountNumber).Select(w => new AccountTransaction
                {
                    Account_Number = w.Account_Number,
                    Account_Balance = (decimal?)0M,
                    Deposit = (decimal?)w.Amount,
                    Withdrawal = (decimal?)null,
                    Date = w.Date,
                     Account_Type=null,  
                    Account_Holder_Tittle = null,
                    Account_Holder_FirstName =null,
                    Account_Holder_LastName = null
                }).Union(context.Current_Account_Withdraw.Where(x => x.Account_Number == accountNumber).Select(d => new AccountTransaction
                {
                    Account_Number = d.Account_Number,
                    Account_Balance = (decimal?)0M,
                    Deposit = (decimal?)null,
                    Withdrawal = (decimal?)d.Amount,
                    Date = d.Date,
                    Account_Type = null,
                    Account_Holder_Tittle = null,
                    Account_Holder_FirstName = null,
                    Account_Holder_LastName = null
                })).OrderBy(r => r.Date)
                .Union(context.Current_Account_Details.Where(x => x.Account_Number == accountNumber).Select(e => new AccountTransaction
                {
                    Account_Number = e.Account_Number,
                    Account_Balance = (decimal?)e.Account_Balance,
                    Deposit = (decimal?)0M,
                    Withdrawal = (decimal?)0M,
                    Date = e.Account_Creation_Date,
                    Account_Type=e.Account_Type,  
                    Account_Holder_Tittle = null,
                    Account_Holder_FirstName =null,
                    Account_Holder_LastName = null

                }))
                .Union(context.Current_Account_Holder_Details.Where(x=>x.Account_Number ==accountNumber).Select(d=> new AccountTransaction
                {
                    Account_Number = d.Account_Number,
                    Account_Balance = null,
                    Deposit =null,
                    Withdrawal = null,
                    Date = null,
                    Account_Type = null,
                    Account_Holder_Tittle =d.Tittle,
                    Account_Holder_FirstName=d.Account_Holder_First_Name,
                    Account_Holder_LastName=d.Account_Holder_Last_Name


                }));
                var js = new System.Web.Script.Serialization.JavaScriptSerializer();
                return js.Serialize(inOut);
            }
        }

这是Angularjs代码。

我无法看到您在哪里显示帐户标签?您只显示这些列

            <th> Account Number</th>
            <th> Money In</th>
            <th>Date</th>
            <th> Money Out</th>
            <th>Date</th>
