asp.net中实现CheckBoxList单选功能

定义函数

<script language="javascript" type="text/javascript">
        function CheckSelect() {
            var cbl = document.getElementById("CheckBoxList1");
            for (var i = 0; i < cbl.rows.length; i++)  {
                var chk = cbl.rows[i].firstChild.firstChild;
                if (chk != event.srcElement){
                    chk.checked = false;

                }
            }
        }
 </script>

给控件添加定义的函数

 <asp:CheckBoxList onclick="javascript:CheckSelect();"  ID="CheckBoxList1" runat="server">
                </asp:CheckBoxList>
