如何获取html控件的值？？？？
C# code我前台基本上判断好了，，前台代码 <script language="javascript" type="text/javascript"> var len; var sum; var maxnum = 100000;//最大投注金额 var issue ='8878' var ishave ='1' function chCI(idval) { if(issue=='3131') { if (document.getElementById("CI"+idval).checked == true) { document.getElementById(idval).value = 1; } else { document.getElementById(idval).value = 0; } } else { if (document.getElementById("CI"+idval).checked == true) { document.getElementById(idval).value = 10; } else { document.getElementById(idval).value = 0; } } fo(idval); } function fo(idval) { var regex=/^[1-9]\d{0,}$/; var val; len = document.getElementsByName("SMONEY").length; sum = 0; for (i=0;i<parseInt(len);i++) { val = document.getElementsByName("SMONEY")[i].value; if(regex.test(val)&&(document.getElementsByName("CI")[i].disabled==false)) { document.getElementsByName("CI")[i].checked = true; sum = parseInt(sum)+parseInt(val); } else if (document.getElementsByName("CI")[i].disabled==false) { document.getElementsByName("CI")[i].checked = false; document.getElementsByName("SMONEY")[i].value = ""; } } if (parseInt(sum)>parseInt()) { document.getElementById(idval).value = ""; fo(idval); alert("您的经验不足！"); } if(sum>maxnum) { alert("对不起，总投注金额不能超过投注上限！"); return false; } document.getElementById("SMONEYSUM").value = sum; } </script> <asp:Repeater ID="rpt310GuessAdd" runat="server" onitemdatabound="rpt310GuessAdd_ItemDataBound" > <HeaderTemplate> <table class="sanyaolingtables sanyaolingTable" style=" border-collapse:collapse;font-weight:bold; "><tr> <td class="syl_add_tdOne">预测结果</td> <td class="syl_add_tdTwo">结果解释</td> <td class="syl_add_tdThree">当前赔率</td> <td class="syl_add_tdThree">请选择</td> <td class="syl_add_tdOne">竞猜</td> </tr></table> </HeaderTemplate> <ItemTemplate> <table class="sanyaolingTable" style=" border-collapse:collapse; color:#515151; "><tr> <td class="syl_add_tdOne"> <asp:Label ID="lblresult" runat="server" Text='<%#Eval("Guess_310_Child_Result") %>'></asp:Label></td> <td class="syl_add_tdTwo"> <asp:Label ID="lblExplanation" runat="server" Text='<%#Eval("Guess_310_Child_Explanation") %>'></asp:Label></td> <td class="syl_add_tdThree"> <asp:Label ID="lblpeilv" runat="server" Text=""></asp:Label></td> <td class="syl_add_tdThree"> <input name="CI" id="CI<%#Eval("Guess_310_Child_Result") %>" type="checkbox" value='<%#Eval("Guess_310_Child_Result") %>' onclick="chCI('<%#Eval("Guess_310_Child_Result") %>');"/> <asp:Label ID="lblqishu" runat="server" Text='<%#Eval("Guess_310_Child_QiShu") %>' Visible="false"></asp:Label> </td> <td class="syl_add_tdOne"> <input id="<%#Eval("Guess_310_Child_Result") %>" name="SMONEY" type="text" size="15" value="0" onkeyup="if(event.keyCode !=37 && event.keyCode != 39) value=value.replace(/\D/g,'');fo('<%#Eval("Guess_310_Child_Result") %>');" onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/\D/g,''))" onclick="chCI('<%#Eval("Guess_310_Child_Result") %>');"/> </td> </tr></table> </ItemTemplate> </asp:Repeater> <table class="sanyaolingTable" style=" border-collapse:collapse; color:#515151;"><tr> <td colspan="5"> 我的总竞猜额：<input id="SMONEYSUM" name="SMONEYSUM" type="text" readonly="readonly" value="0" /></td> </tr> <tr> <td colspan="5"> <asp:Button ID="btnOK" runat="server" Text="确认" onclick="btnOK_Click" /></td> </tr> </table> 后台： protected void rpt310GuessAdd_ItemDataBound(object sender, RepeaterItemEventArgs e) {//这里如何获取ck和SMONEY的值} protected void btnOK_Click(object sender, EventArgs e) { HtmlInputCheckBox ck; //一个是ck for (int i = 0; i < rpt310GuessAdd.Items.Count; i++) { ck = (HtmlInputCheckBox)rpt310GuessAdd.Items[i].FindControl("CI"); if (ck.Checked) { //查找SMONEY的值 } } }注释：如果我加个runat="server"就报错了，，就说：服务器标记的格式不正确，，，求解啊
