用js操作gridview的RadioButton值

前台：

  <asp:GridView ID="gridViewListNew" runat="server" AutoGenerateColumns="False" AllowSorting="True"
                OnSorting="GridViewListSorting" DataKeyNames="FamiliesID" Visible="false" OnRowDataBound="GridViewNew_RowDataBound"
                ClientIDMode="Static" CssClass="jqGrid">
                <Columns>
                    <asp:TemplateField HeaderText="选择">
                        <ItemTemplate>
                            <asp:HiddenField ID="hdfCountieID" runat="server" Value='<%#Eval("CountieID") %>' />
                            <asp:HiddenField ID="hdfTownShipID" runat="server" Value='<%#Eval("TownShipID") %>' />
                            <asp:HiddenField ID="hdfVillageID" runat="server" Value='<%#Eval("VillageID") %>' />
                            <asp:HiddenField ID="hdfGroupID" runat="server" Value='<%#Eval("GroupID") %>' />
                               <asp:HiddenField ID="primayKeyId" Value='<%#Eval("FamiliesID")%>' runat="server" />
                                <asp:HiddenField ID="hidLockStatus" Value='<%#Eval("FamilyLockStatus")%>' runat="server" />  
                            <asp:RadioButton ID="rbFamily" runat="server" GroupName="choose"/>
                        </ItemTemplate>
                        <HeaderStyle CssClass="alignCenter" Width="50px" />
                    </asp:TemplateField>

<Columns>

</asp:GridView>
    <asp:HiddenField ID="hfrbFamilyid" runat="server"/>

js

<script>

function onClientClick(selectedId, memberid) {
            //用隐藏控件记录下选中的行号
            var inputs = document.getElementById("<%=gridViewListNew.ClientID%>").getElementsByTagName("input");
            for (var i = 0; i < inputs.length; i++) {
                if (inputs[i].type == "radio") {
                    if (inputs[i].id == selectedId) {
                        inputs[i].checked = true;
                        document.getElementById("<%=hfrbFamilyid.ClientID %>").value = memberid;
                    }
                    else
                        inputs[i].checked = false;
                }
            }
        }
    </script>

gridview绑定事件中：

 private void GridViewNewRowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.Header)
            {
                InitControl.ShowSortedIcon(gridViewListNew, e.Row, ViewState["SortExpression"].ToString(), ViewState["SortDirection"].ToString());
            }
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                HiddenField hddf = e.Row.Cells[0].FindControl("primayKeyId") as HiddenField; //表主键ID
                RadioButton rb = (RadioButton)e.Row.FindControl("rbFamily");
                if (rb != null)
                    rb.Attributes.Add("onclick",
                                      "onClientClick('" + rb.ClientID + "','" + hddf.Value +
                                      "')");
                             
            }
        }

后台获取直接用 hfrbFamilyid.value就可以了
