ASP.NET MVC 排球计分程序 （六）HomeController代码和一些解释
Index Action方法 （默认进入的主页）
public ActionResult Index() { return View(); }
AddPerson Action方法（单击主页提交 将交到AddPerson里来处理数据，并将队员 名字插入数据库）
public ActionResult AddPerson() { //获取填入的衣服编号和名字 并将其写入数据库 //编号idA1 nameA1 SqlHelper.ClearBiaoRen(); //插入B的idB1 nameB1.. int numsA = 1; //将十二个队员全部插入数据库 总共有十二个文本框 执行<=12次的循环 插入值 while (numsA <= 12) { //获取文本框名为idB1到idB12的值 int idA = int.Parse(Request["idA" + numsA]); //获取文本框名为nameB1到nameB12的值 string name = Request["nameA" + numsA]; //排除name为空的情况 if (string.IsNullOrEmpty(name)) { numsA++; continue; } else { //name不为空插入 idB1 nameA1等进数据库 string sql = "insert into PersonA values(" + idA + ",‘" + name + "‘)"; int a = SqlHelper.ExecuteNonQuery(sql, null); if (a > 0) { ViewBag.IsSuccessA = ""; } else { ViewBag.IsSuccessA = "A插入失败，未知错误"; } } numsA++; } //插入B的idB1 nameB1.. int numsB = 1; //将十二个队员全部插入数据库 总共有十二个文本框 执行<=12次的循环 插入值 while (numsB <= 12) { //获取文本框名为idB1到idB12的值 int idB = int.Parse(Request["idB" + numsB]); //获取文本框名为nameB1到nameB12的值 string name = Request["nameB" + numsB]; //排除name为空的情况 if (string.IsNullOrEmpty(name)) { numsB++; continue; } else { //name不为空插入 idB1 nameA1等进数据库 string sql = "insert into PersonB values(" + idB + ",‘" + name + "‘)"; int a = SqlHelper.ExecuteNonQuery(sql, null); if (a > 0) { ViewBag.IsSuccessB = ""; } else { ViewBag.IsSuccessB = "B插入失败，未知错误"; } } numsB++; } //string teamAName = Request["teamAName"]; //string teamBName = Request["teamBName"]; //获取teamA teamB文本框内的值 ViewBag.teamAName = Request["teamAName"]; ViewBag.teamBName = Request["teamBName"]; //显示当前比分 局分都是0 ViewBag.dangQianA = "0"; ViewBag.dangQianB = "0"; ViewBag.juA = "0"; ViewBag.juB = "0"; List<PersonA> personA = SqlHelper.GetAllPersonA(); //ViewData["PersonA"] = new SelectList(personA, "id","name"); //List<SelectListItem> items = new List<SelectListItem>(); //items.Add(new SelectListItem { Text = "Kirin", Value = "http://www.mamicode.com/29" }); //items.Add(new SelectListItem { Text = "Jade", Value = "http://www.mamicode.com/28" }); //items.Add(new SelectListItem { Text = "Yao", Value = "http://www.mamicode.com/24" }); //this.ViewData["list"] = personA; //this.ViewData["selected"] = 24; StringBuilder sb = new StringBuilder(); sb.Append("<select id=\"teamA\">"); for (int i = 0; i < personA.Count; i++) { sb.AppendFormat(" <option value =http://www.mamicode.com/teamA{0}>{1}", i, personA[i].id); } sb.Append("</select>"); ViewBag.DropDownListA = sb.ToString(); string[] jiQius = { "拦网", "发球", "扣球", "抹球", "一传" }; StringBuilder sb1 = new StringBuilder(); sb1.Append("<select id=\"teamAJiQiu\">"); for (int i = 0; i < jiQius.Length; i++) { sb1.AppendFormat(" <option value =http://www.mamicode.com/teamAJiQiu{0}>{1}", i, jiQius[i]); } sb1.Append("</select>"); ViewBag.DropDownListJiQiu = sb1.ToString(); StringBuilder sb2 = new StringBuilder(); sb2.Append("<select id=\"teamAIsFen\">"); sb2.AppendFormat(" <option value =http://www.mamicode.com/teamAIsFen{0}>{1}", 1, "是"); sb2.AppendFormat(" <option value =http://www.mamicode.com/teamAIsFen{0}>{1}", 2, "否"); sb2.Append("</select>"); ViewBag.DropDownListIsFen = sb2.ToString(); //A队结束 //B队开始 List<PersonB> personB = SqlHelper.GetAllPersonB(); //ViewData["PersonA"] = new SelectList(personA, "id","name"); //List<SelectListItem> items = new List<SelectListItem>(); //items.Add(new SelectListItem { Text = "Kirin", Value = "http://www.mamicode.com/29" }); //items.Add(new SelectListItem { Text = "Jade", Value = "http://www.mamicode.com/28" }); //items.Add(new SelectListItem { Text = "Yao", Value = "http://www.mamicode.com/24" }); //this.ViewData["list"] = personA; //this.ViewData["selected"] = 24; StringBuilder sbB = new StringBuilder(); sbB.Append("<select id=\"teamB\">"); for (int i = 0; i < personB.Count; i++) { sbB.AppendFormat(" <option value =http://www.mamicode.com/teamB{0}>{1}", i, personB[i].id); } sbB.Append("</select>"); ViewBag.DropDownListB = sbB.ToString(); string[] jiQiusB = { "拦网", "发球", "扣球", "抹球", "一传" }; StringBuilder sb1B = new StringBuilder(); sb1B.Append("<select id=\"teamBJiQiu\">"); for (int i = 0; i < jiQiusB.Length; i++) { sb1B.AppendFormat(" <option value =http://www.mamicode.com/teamBJiQiu{0}>{1}", i, jiQiusB[i]); } sb1B.Append("</select>"); ViewBag.DropDownListJiQiuB = sb1B.ToString(); StringBuilder sb2B = new StringBuilder(); sb2B.Append("<select id=\"teamBIsFen\">"); sb2B.AppendFormat(" <option value =http://www.mamicode.com/teamBIsFen{0}>{1}", 1, "是"); sb2B.AppendFormat(" <option value =http://www.mamicode.com/teamBIsFen{0}>{1}", 2, "否"); sb2B.Append("</select>"); ViewBag.DropDownListIsFenB = sb2B.ToString(); return View("AddScore"); }
这个Action主要写了插入名字到对应的PersonA PersonB 数据库
弹出新的界面应显示的一些内容
如队名 根据自己在数据库中插入的内容而生成的下拉列表 队名的传递也可以使用Cookie 和session这里不做解释
ViewBag.名字 可以用来传递数据
在视图中用@VieWBag名字 可以获取到自己传递的值 详情可以了解一下Rezor语法等
Admin Action方法
public ActionResult Admin() { //获取文本框的值 //获取是A队得分还是B队得分 string teamMing = Request["teamMing"]; //获取A队的名字 string teamAName = Request["tA"]; //获取B队的名字 string teamBName = Request["tB"]; //重新将名称写入文本框 ViewBag.teamAName = teamAName; ViewBag.teamBName = teamBName; //获取是哪一个球员 string teamYuan = Request["teamYuan"]; //获取它是哪一种状态 string teamTai = Request["teamTai"]; //获取当前状态是否得分 string teamIsFen = Request["teamIsFen"]; //获取当前比分A队的值 //int dangQianA; //if (string.IsNullOrEmpty(Request["dangQiangA"])) //{ // dangQianA = 0; //} //else //{ // dangQianA = int.Parse(Request["dangQiangA"]); //} ////获取当前比分B队的值 //int dangQianB; //if (string.IsNullOrEmpty(Request["dangQiangB"])) //{ // dangQianB = 0; //} //else //{ // dangQianB = int.Parse(Request["dangQiangB"]); //} ////获取局比分A //int juA; //if (string.IsNullOrEmpty(Request["juA"])) //{ // juA = 0; //} //else //{ // juA = int.Parse(Request["juA"]);

AddScore Action
public ActionResult AddScore() { return View(); }
selectScore
public ActionResult selectScore() { ViewBag.AMaxFen = SqlHelper.getAMaxScore(); ViewBag.BMaxFen = SqlHelper.getBMaxScore(); ViewBag.AFaQiu = SqlHelper.getAFaQiuMax(jiQiu.发球); ViewBag.BFaQiu = SqlHelper.getBFaQiuMax(jiQiu.发球); ViewBag.AYiChuan = SqlHelper.getAFaQiuMax(jiQiu.一传); ViewBag.BYiChuan = SqlHelper.getBFaQiuMax(jiQiu.一传); ViewBag.AKouQiu = SqlHelper.getAFaQiuMax(jiQiu.扣球); ViewBag.BKouQiu = SqlHelper.getBFaQiuMax(jiQiu.扣球); ViewBag.AMoQiu = SqlHelper.getAFaQiuMax(jiQiu.抹球); ViewBag.BMoQIu = SqlHelper.getBFaQiuMax(jiQiu.抹球); ViewBag.ALanWang = SqlHelper.getAFaQiuMax(jiQiu.拦网); ViewBag.BLanWang = SqlHelper.getBFaQiuMax(jiQiu.拦网); return View(); }
