获取DataList控件中的值

Question

<form id="form1" runat="server">
<div id="container" style="width: 800px; height: 400px; margin: 0 auto"></div>
        <asp:DataList ID="DataList1" runat="server" Width="263px">
            <ItemTemplate>
                     <table id="datatable">
                        <tr>
                            <th style="width: 60px">
                                Apples</th>
                            <td id="c_homologyCount">
                                <%# Eval("c_homologyCount") %></td>
                            <td style="width: 35px">
                                <%# Eval("c_differCount") %></td>
                        </tr>
                </table>
            </ItemTemplate>
        </asp:DataList>
 </form>
DataList 控件中的数据只显示一条，怎样用JS获取ID为c_homologyCount的这一列。

Answer 1

document.getElementByID('c_homologyCount')

Answer 2

最好用一个控件来显示 找的时候好找。function test() {
            var dl = document.getElementById("DataList1").children[0];
            var n1 = dl.children.length; //行数即记录数
            var n2 = dl.children[0].getElementsByTagName("SPAN").length; //一行中的字段数
            for (var i = 0; i < n1; i++) {
                var s = "";
                for (var j = 0; j < n2; j++) {
                    s += dl.children[i].getElementsByTagName("SPAN").item(j).innerHTML + ",";
                }
                alert(s);
            }
        }

Answer 3

protected void DataList1_ItemCommand(object source, DataListCommandEventArgs e)
    {
        if (e.CommandSource.GetType() == typeof(LinkButton))
        {
            if (((LinkButton)e.CommandSource).CommandName == "accept")
            {
                Response.Write("<script language='javascript'>alert('"+((LinkButton)e.Item.FindControl("accept")).Text+"')</script>");
                Response.Write(((Label)e.Item.FindControl("blogName")).Text);           
 }
        }
    }

Answer 4

最好用服务器控件
document.getElementById("DataList1_ctl00_Label1").innerHTML;
