1.html檔案中引入另一個html檔案，用 #parse("../include/header.htm")，最好不要用<iframe  scrolling="no" marginwidth="0" marginheight="0" width="100%" height="50" src="/include/header.htm" frameborder="0"></iframe>這種形式的

2.需要連線資料庫和匯入sqlhelper(資料庫裡邊的一些方法)和引用Nvelocity(渲染html頁面)

連線資料庫需要在web.config中配置：

<connectionStrings>
    <add name="connstr" connectionString="Data Source=.;Initial Catalog=stuentsystem;User Id=sa;Password=136156a;"/>        --stuentsystem資料庫名稱
  </connectionStrings>

3.可以往Data存多個數據：

                    DataTable dt = SqlHelper.ExecuteDataTable("select * from class where [email protected]_ID", new SqlParameter("@CLASS_ID", id));
                    DataTable dts = SqlHelper.ExecuteDataTable("select * from teacher");
                    var Data = new { team = dt.Rows[0], teachers=dts.Rows};
                    string html = CommonHelper.RenderHtml("editteam.html", Data);
                    context.Response.Write(html);

相應的前臺可以通過$Data.team和$Data.teachers呼叫

4.比如班級（班級表中）裡邊得到所有的班主任老師名稱（在另一個數據表teacher中）  新增頁面

相當於遍歷老師表：

前臺：<td>
                <select name="teacher">    
                <option>請選擇</option>
                   #foreach($p in $Data.teachers)                 
                  <option value="$p.TEACHER_ID">$p.NAME</option>     
                  #end                        
                </select>
              </td>

後臺（需要得到teachers）：

              DataTable dt = SqlHelper.ExecuteDataTable("select * from teacher");
                var Data = new { teachers = dt.Rows };
                string html = CommonHelper.RenderHtml("addteam.html", Data);
                context.Response.Write(html);

5.編輯頁面    顯示已經選擇的老師名稱，並且遍歷

前臺：

           <tr>
              <td>班主任老師</td>
              <td>
                <select name="teacher">
                 #foreach($p in $Data.teachers)
                        #if($Data.team.TEACHER_ID == $p.TEACHER_ID)        --班級裡的老師ID和教師表裡的id一致的時候，顯示老師名稱；否則顯示所有的老師名稱
                        <option value="$p.TEACHER_ID" selected="selected">$p.NAME</option>
                        #else
                        <option value="$p.TEACHER_ID">$p.NAME</option>
                        #end
                 #end            
                </select>
              </td>
            </tr>

後臺：需要得到當前編輯的班級和教師列表

                  DataTable dt = SqlHelper.ExecuteDataTable("select * from class where [email protected]_ID", new SqlParameter("@CLASS_ID", id));
                    DataTable dts = SqlHelper.ExecuteDataTable("select * from teacher");
                    var Data = new { team = dt.Rows[0], teachers=dts.Rows};
                    string html = CommonHelper.RenderHtml("editteam.html", Data);
                    context.Response.Write(html);

6.模糊查詢：

 DataTable dt = SqlHelper.ExecuteDataTable("select * from class_teacher where C_NAME like @C_NAME", new SqlParameter("@C_NAME", "%" + searchText + "%"));                                                                                                                                                                                                     --searchText為輸入框的name

好了，現在就這麼多吧，別的問題暫時還沒怎麼遇到呢
