Question

这是我的ASP代码，以HTML表格的形式显示数据库表

if (operation == "display"){
    MySqlDataAdapter da = new MySqlDataAdapter("select StudentId, StudentName from tblStudent where StudentStatus = 'a'", con);
    DataTable dt = new DataTable();
    da.Fill(dt);
    Response.Write("<Table cellpadding = 5>");
    Response.Write("<tr>");
    Response.Write("<th>");
    Response.Write("Student Id");
    Response.Write("</th>");
    Response.Write("<th>");
    Response.Write("Student Name");
    Response.Write("</th>");
    Response.Write("</tr>");
    foreach (DataRow dr in dt.Rows){
       Response.Write("<tr>");
       Response.Write("<td>");
       Response.Write(dr["StudentId"].ToString());
       Response.Write("</td>");
       Response.Write("<td>");
       Response.Write(dr["studentName"].ToString());
       Response.Write("</td>");
       Response.Write("</tr>");
   }
   Response.Write("</Table>");
}

这是我的插入代码：

if (operation == "insert"){
    string sid, sname;
    sid = Request.QueryString["StudentId"].ToString();
    sname = Request.QueryString["StudentName"].ToString();
    //MySqlDataAdapter da = new MySqlDataAdapter("insert into tblStudent (StudentId, StudentName) values (sid, sname)", con);
    con.Open();
    MySqlCommand cmd = con.CreateCommand();
    cmd.CommandType = CommandType.Text;
    cmd.CommandText = "insert into tblStudent (StudentId, StudentName) values('" + sid.ToString() + "', '" + sname.ToString() + "')";
    cmd.ExecuteNonQuery();
    con.Close();
}

它工作得很好。但是当我执行插入操作时，我不想再读取整个表格。我只想将行追加到HTML表中，当cmd.ExecuteNonQuery返回1时（在确保数据库表更新时），该表在display方法中定义。怎么样？

在你的ajax后续回调中将新行附加到表

succcess:function(data)
{
    var newRow= "";                   
    newRow= newRow+ "<tr>";
    newRow= newRow+ "<td>" + studentId + "</td>";
    newRow= newRow+ "<td>" + studentName + "</td>";      
    newRow= newRow+ "</tr>";                        
    $('.yourtable').append(newRow);
}

Answer 2

使用runat =＆＃39; server＆＃39;创建HTML表作为服务器端控件。因此，您的表创建部分将如下所示;

**Response.Write("<Table runat='server' id='tblStudents' cellpadding = 5>");**

保存后，您可以从后面的代码访问此控件并添加行。成功插入后添加以下代码;

var row= new System.Web.UI.HtmlControls.HtmlTableRow();
var cellSID = new System.Web.UI.HtmlControls.HtmlTableCell();
cellSID.InnerText = sid;
row.Cells.Add(cellSID);

 var cellSName = new System.Web.UI.HtmlControls.HtmlTableCell();
 cellSID.InnerText = sname;
 row.Cells.Add(cellSName);

 tblStudents.Rows.Insert(0, row);

Answer 3

我会建议使用jquery＆＃39; s append。它会在找到tbody的{{1}}中的最后一个孩子后追加行：

table

注意：表格至少应有一个$('#yourTableID > tbody:last-child').append('<tr><td>Some Data</td>...</tr>');，您可以通过使用jquery计算表格中的行来轻松完成此操作。
