客車網上售票系統（分解五）
阿新 • • 發佈：2020-08-09
1、今日完成任務:
(1)改簽分解功能1：點選改簽根據當前訂單的出發地和目的地查詢車票資訊並顯示（發車日期可以改動，出發地和目的地是固定不能變得）
(2)改簽分解功能2:選好需要改動的車票點選查詢頁面的改簽，跳轉到詳情頁面分別顯示需要改簽前的車票資訊和需要改簽後的車票資訊
(3)改簽分解功能3：點選提交訂單，顯示當前訂單的詳細資訊並提醒使用者抓緊時間支付
(4)改簽分解功能4：點選立即改簽即改簽成功並跳轉回我的訂單頁面
2、核心原始碼:

1.點選改簽按鈕跳轉頁面 /// <summary> /// 改簽 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e) { int oid = Convert.ToInt32(this.GridView1.DataKeys[e.RowIndex].Value); //跳轉到查詢車票頁面車票頁面 Response.Redirect("GQ.aspx?oid="+oid); } 2.根據傳遞的oid資訊查詢出出發地和目的地並顯示出所有滿足條件的車票資訊 public partial class GQ : System.Web.UI.Page { OrderinfoManager bll = new OrderinfoManager(); CarinfoManager carBll = new CarinfoManager(); protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { //繫結控制元件 int oid = Convert.ToInt32(Request.QueryString["oid"]); //根據oid查詢資訊並繫結在文字框中 DataSet ds = bll.SelectByOid(oid); this.txtCfd.Text = ds.Tables[0].Rows[0]["Begin_sta"].ToString(); this.txtMdd.Text= ds.Tables[0].Rows[0]["End_sta"].ToString(); Session["oid"] = oid; this.GridView1.DataSource = carBll.GetData(); this.GridView1.DataBind(); } } 3.根據使用者輸入的查詢日期進行查詢 /// <summary> /// 查詢 /// </summary> /// <param name="sender"></param> /// <param name="e"></param> protected void btnSelect_Click(object sender, EventArgs e) { //從前臺獲取資料 //出發地 string cfd = this.txtCfd.Text; //目的地 string mdd = this.txtMdd.Text; string date = DateTime.MinValue.ToString(); if (this.test1.Text != "") { //出發日期 date = this.test1.Text; } this.GridView1.DataSource = carBll.GetDataByInfo(cfd, mdd, date); this.GridView1.DataBind(); } } DAL層： public DataSet SelectByOid(int oid) { string sql = $"select *from Orderinfo inner join Carinfo on Orderinfo.Cid=Carinfo.Cid where Oid={oid}"; DataSet ds = dbHelper.GetData(sql); return ds; } public DataSet GetDataByInfo(string beginSta,string endSta,string date) { string sql = $"select * from Traininfo inner join Carinfo on Traininfo.Tid=Carinfo.Tid where Cmark=0 and 1=1 "; if (beginSta!="") { sql += $"and Begin_sta ='{beginSta}'"; } if (endSta!="") { sql += $"and End_sta='{endSta}'"; } if (date!=DateTime.MinValue.ToString()) { sql += $"and Start_date='{date}'"; } DataSet ds = dbHelper.GetData(sql); return ds; }

3、遇到的問題:
(1)改簽功能需要考慮的東西比較多，容易漏寫功能
(2)很多想實現的效果因為能力有限沒辦法實現，需要前端技術
4、解決的方法:
(1)網上搜索12306改簽流程實現
(2)技術能力方面需要利用這個暑假做提升
