怎么获得js获取复选框的选中的值 [

[litengfei0020]

这是我运行以后的效果 我点提交以后 希望可以把复选框所代表的具体的值写到数据库中

这是我的aspx 代码
<%@ Page Language="C#" MasterPageFile="~/manageCenter/Manage.master" AutoEventWireup="true"
CodeFile="joinVote.aspx.cs" Inherits="manageCenter_joinVote" Title="无标题页" %>

<asp:Content ID="Content1" ContentPlaceHolderID="CPH" runat="Server">

<script type="text/javascript" src="../js/base.js"></script>

<div class="mngTitle">
<asp:Label ID="lblTit" runat="server" Text=""></asp:Label></div>
<table>
<tr>
<td>
<aspataList ID="dlTitle" runat="server" OnItemDataBound="dlTitle_ItemDataBound">
<ItemTemplate>
<table>
<tr>
<td style="background-color: #CBDDDD;">
<asp:Label ID="labFileType" runat="server" Visible="False" Text='<%# Eval("id")%>'>
</asp:Label><%# Eval("title") %>
</td>
</tr>
<tr>
<td>
<aspataList ID="dlAn" runat="server" RepeatDirection="Horizontal">
<ItemTemplate>
<table>
<tr>
<td>
<input type="checkbox" name="answer" runat="server" />
</td>
<td>
<%#Eval("answer") %>
</td>
<td>
</td>
</tr>
</table>
</ItemTemplate>
</aspataList>
</td>
</tr>
</table>
</ItemTemplate>
</asp:DataList>
</td>
</tr>
<tr>
<td>
<input type="button" runat="server" value="提交" onclick="GetSelectValue()" />
</td>
</tr>
</table>
</asp:Content>
