Question

我重复了项目模板:

<asp:Repeater ID="queryParametersRepeater" runat="server" 
  DataSourceID="queryParametersObjectDataSource">
  <ItemTemplate>
    <tr class="itemTemplate">
      <td class="labelTd" style="width: 300px;">
        <asp:HiddenField runat="server" Value= <%# Eval("ParameterType") %>  />
        Define <%# Eval("ParameterName") %> (type <%# Eval("ParameterType") %>)
      </td>                        
      <td class="valueTd">                            
        <asp:TextBox runat="server" Width="300px" Text= <%# Eval("ParameterName") %>  />
        <asp:CheckBox runat="server" Width="300px" />
      </td>
    </tr>
  </ItemTemplate>                
</asp:Repeater>

在j Query I的改动中,显示文本Box和chekBox的财产。我如何能够从这些控制中获得数据?

I can t use FindControls() function, because I don t know id of my controls.

你们可以使用国际发展法,并设法控制这些价值观。这方面的一个例子是:

<%@ Page Language="C#" %>
<%@ Import Namespace="System.Collections.Generic" %>

<script runat="server">

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            //bind the data source
            RepeaterExample.DataSource = new List<KeyValuePair<int, string>>{
                new KeyValuePair<int,  string>(1, "Test1"), 
                new KeyValuePair<int,  string>(2, "Test2"), 
                new KeyValuePair<int,  string>(3, "Test3")
            };
            RepeaterExample.DataBind();
        }

    }

    protected void cmdSubmit_Click(object sender, EventArgs e)
    {
            //read the values and output them
            litResults.Text = "";
            foreach (RepeaterItem i in RepeaterExample.Items)
            {

                TextBox txtExample = (TextBox)i.FindControl("txtExample");
                if (txtExample != null)
                {
                    litResults.Text += txtExample.Text + "<br />";
                }
            }
    }
</script>

<html xmlns="http://www.w3.org/1999/xhtml">
    <head runat="server">
    </head>
    <body>
        <form id="form1" runat="server">
            <div>
                <asp:Repeater ID="RepeaterExample" runat="server">
                    <HeaderTemplate>
                        test</HeaderTemplate>
                    <ItemTemplate>
                        <asp:TextBox ID="txtExample" runat="server" Text= <%#Eval("Value") %> ></asp:TextBox>
                    </ItemTemplate>
                </asp:Repeater><br />
                <asp:Button ID="cmdSubmit" runat="server" Text="Submit" OnClick="cmdSubmit_Click" />
                <br />
                <asp:Literal ID="litResults" runat="server"></asp:Literal>
            </div>
        </form>
    </body>
</html>

Answer 2

Can you add a class to your controls? If so you could try with $(".givenClass").
