asp.ent 弹出选择‘确定’‘取消’的提示框

在页面写javascript代码

               function isConf()

                             {
                               if(window.confirm("确认删除吗？"))

                               {
                                  return true;
                               }
                                 else{
                                      return false;
                                       }
                           }

这是控件的事件

<asp:Button ID="Button1" runat="server" Text="Button"  onclick="Button1_Click" OnClientClick="return isConf();" />

注意：return 返回false时不会执行onclick事件，只有返回ture时才会执行onclick事件。
