jQuery csscody confirm整合GridView的刪除提示

一般若要在GridView按下刪除鈕時出現提示訊息的話
 <asp:TemplateField ShowHeader="False">
                <ItemTemplate>
                    <asp:Button ID="btn_Delete" runat="server" CausesValidation="False" CommandArgument='<%# Eval("CategoryID") %>'
                        OnClientClick="return confirm('您確定要刪除？');" CommandName="Delete" Text="刪除" />
                </ItemTemplate>
 </asp:TemplateField>
