以前學習ASP.NET MVC時，學習與應用，操作過數(shù)據(jù)顯示，添加，編輯，更新和刪除等功能。
很多方法是相通的，看自己是怎樣來進行方便，快捷，高效率。
今天Insus.NET寫的練習，是直接對綁定在Table的數(shù)據(jù)進行更新，刪除。
在項目中，創(chuàng)建一個實體，也就是說，對數(shù)據(jù)庫時行通信，對數(shù)據(jù)進行操作：

public IEnumerable<ToolLocation> GetAllToolLocations()
  {
   sp.ConnectionString = DB.ConnectionString;
   sp.Parameters = null;
   sp.ProcedureName = "usp_ToolLocation_GetAll";
   DataTable dt = sp.ExecuteDataSet().Tables[0];
   return dt.ToList<ToolLocation>();
  }

  public void Update(ToolLocation tl)
  {
   List<Parameter> param = new List<Parameter>() {
         new Parameter("@ToolLocation_nbr", SqlDbType.SmallInt, 2, tl.ToolLocation_nbr),
         new Parameter("@LocationName",SqlDbType.NVarChar,-1,tl.LocationName),
         new Parameter("@Description",SqlDbType.NVarChar,-1,tl.Description),
         new Parameter("@IsActive",SqlDbType.Bit,1,tl.IsActive)
   };
   sp.ConnectionString = DB.ConnectionString;
   sp.Parameters = param;
   sp.ProcedureName = "usp_ToolLocation_Update";
   sp.Execute();
  }

  public void Delete(ToolLocation tl)
  {
   List<Parameter> param = new List<Parameter>() {
         new Parameter("@ToolLocation_nbr", SqlDbType.SmallInt, 2, tl.ToolLocation_nbr)
   };
   sp.ConnectionString = DB.ConnectionString;
   sp.Parameters = param;
   sp.ProcedureName = "usp_ToolLocation_Delete";
   sp.Execute();
  }

在項目的控制器中：

創(chuàng)建視圖，并綁定數(shù)據(jù)：

@using Insus.NET.Models;
@model IEnumerable<ToolLocation>

<!DOCTYPE html>
<html>
<head>
 <meta name="viewport" content="width=device-width" />
 <title>Edit</title>
 <link href="~/Content/css/table.css" rel="stylesheet" />
 <script src="~/Scripts/jquery-2.2.1.js"></script>
 
</head>
<body>
 <div>
  <table>
   <tr>
    <td>ToolLocation_nbr</td>
    <td>LocationName</td>
    <td>Description</td>
    <td>IsActive</td>
    <td></td>
   </tr>
   @foreach (var tl in Model)
   {
    <tr>
     <td>@tl.ToolLocation_nbr<input id="Hidden1" type="hidden" value="@tl.ToolLocation_nbr" /></td>
     <td>@Html.TextBox("LocationName", tl.LocationName)</td>
     <td>@Html.TextBox("Description", tl.Description) </td>
     <td>@Html.CheckBox("IsActive", tl.IsActive)</td>
     <td>
      <input class="Update" type="button" title="Update" value="Update" />
     </td>
    </tr>
   }
  </table>
 </div>
</body>
</html>

上面步驟#4的jQuery代碼：

運行一下，看看效果：

上面是對數(shù)據(jù)進行更新的功能，下面的實現(xiàn)，是對Table內的數(shù)據(jù)刪除。

@using Insus.NET.Models;
@model IEnumerable<ToolLocation>

<!DOCTYPE html>

<html>
<head>
 <meta name="viewport" content="width=device-width" />
 <title>Delete</title>
 <link href="~/Content/css/table.css" rel="stylesheet" />
 <script src="~/Scripts/jquery-2.2.1.js"></script>

</head>
<body>
 <div>
  <table>
   <tr>
    <td>ToolLocation_nbr</td>
    <td>LocationName</td>
    <td>Description</td>
    <td>IsActive</td>
    <td></td>
   </tr>
   @foreach (var tl in Model)
   {
    <tr>
     <td>@tl.ToolLocation_nbr<input id="Hidden1" type="hidden" value="@tl.ToolLocation_nbr" /></td>
     <td>@tl.LocationName</td>
     <td>@tl.Description</td>
     <td>@Html.CheckBox("IsActive", tl.IsActive, new { disabled = "disabled" })</td>
     <td>
      <input class="Delete" type="button" title="Delete" value="Delete" />
     </td>
    </tr>
   }
  </table>
 </div>
</body>
</html>

上面標記#4的jQuery代碼，即是刪除的核心功能：
