[ASP.net教程]JQuery对ASP.NET MVC数据进行更新删除


以前学习ASP.NET MVC时,学习与应用,操作过数据显示,添加,编辑,更新和删除等功能。

很多方法是相通的,看自己是怎样来进行方便,快捷,高效率。

今天Insus.NET写的练习,是直接对绑定在Table的数据进行更新,删除。


在项目中,创建一个实体,也就是说,对数据库时行通信,对数据进行操作:

 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();    }

在项目的控制器中:

 
创建视图,并绑定数据:

 

@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>

上面步骤#4的jQuery代码:

 
运行一下,看看效果:


上面是对数据进行更新的功能,下面的实现,是对Table内的数据删除。

@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>

上面标记#4的jQuery代码,即是删除的核心功能:
