编程心得

1、用js判断checkbox是否选中 ，并隐藏控件

<asp:TextBox ID="TB_MessageName" Width="200px" MaxLength="50" runat="server"></asp:TextBox><span
                            style="color: Red;">*50字以内
                            <%--<asp:CheckBox ID="CB_IsRemark" AutoPostBack="false" runat="server" Text="若是类别说明，请打勾" οnclick="ChkClick();" /></span>--%>
                            <input type="checkbox" id="CB_IsRemark"  text="若是类别说明，请打勾" οnclick="ChkClick();"/> 若是类别说明，请打勾</span>

<script language="javascript" type="text/javascript">
        function ChkClick()
        {
            if(document.getElementById("CB_IsRemark").checked)
            {
                $get("<%=TB_MessageName.ClientID %>").style.visibility="hidden";
            }
            else
            {
                $get("<%=TB_MessageName.ClientID %>").Visible=true;
            }
        }
    </script>
