Confirm()方法

一、此方法是 JavaScript 的原生方法,用于显示一个指定消息和带有确定和取消的对话框(显示方式与 alert() 效果类似),当点击确定(或点击回车键)按钮时,会返回 true ,点击取消(或ESC键)则会返回 false <button id="cfm">Confirm测试</button> <script> document.getElementById('cfm').onclick = () => { var test = confirm('测试'); console.log(test) } </script> 运行后效果 点击确定(或点击回车键)后返回true 点击取消(或ESC键)后返回false 二、当此方法执行时,会阻塞后面执行的代码,在未点击确定或取消之前,方法后面的代码不予以执行 <button id="cfm">Confirm测试</button> <script> document.getElementById('cfm').onclick = () => { var test = confirm('测试'); console.log(test); console.log("我在被点击确定或取消后才能打印") } </script> 三、注意:对话框里显示的内容可改变,按钮上的文字不可改变 来源: https://www.cnblogs.com

Can I stop a post back by using javascripts confirm?

问题 I have an aspx page with a asp.net button on the page: <asp:LinkButton ID="btn_Delete" runat="server" OnClick="btn_Delete_Click" OnClientClick="ConfirmDelete();" Text="Delete" /> Confirm delete looks like this: function ConfirmDelete() { var answer = confirm("Are you SURE you want to delete this item?"); if (!answer) { return false; } }; I had assumed that this would prevent the page from posting back if the user clicked cancel, but it still appears to be posting back. Is there some way I can

Best unobtrusive way to add JQuery confirm to an arbitrary element

痴心易碎 提交于 2019-12-01 13:10:12
I'm new to jquery, and am looking for a good unobtrusive way to add a jquery replacement for javascript "confirm" to a HTML elements. Specifically I want to be able to use it for ASP.NET Buttons, LinkButtons, ImageButtons, HyperLink etc, which client-side means any of: <input type="submit"... /> <a href="javascript:__doPostBack... /> <input type="image"... /> ... etc ... A solution I've come up with is to add a custom attribute to the ASP.NET server control (and hence to the client element), e.g.: <asp:ImageButton ... data-confirmPrompt="OK to delete customer 123?" ... /> which renders as:

Android Facebook SDK and URL Methods form successful Friends Dialog, but cannot commit

牧云@^-^@ 提交于 2019-12-01 12:08:59
问题 This is one that I'm beginning to think is a bug, please, Please prove me wrong: I want to programmatically friend a user on Facebook; they are only and most certainly someone the person knows IRL. The following three solutions all have the same result: a successful friends dialog--meaning the profile name, picture, statement indicating the action( to friend someone ), and refusal/confirm buttons; pressing 'confirm' is the problem: it leads to a Facebook error presented in the standard fb UI

分布式事务

在说分布式事务之前,先回顾下事务的相关知识点。 事务 概念 事务指的是一系列数据库操作,它是保证数据库正确性的基本逻辑单元,拥有ACID四个特性:原子性、一致性、隔离性与持久性。 举个例子,下面这两种组成情况都叫做事务: 1.由单个操作序列(一条SQL语句)组成的事务 select * from test; 2.由多个操作序列(SQL语句)组成的事务 select * from test where id = 1; update test(id, name) set name = 'john' where id = 1; 当然,如果我们没有显示声明事务的话,数据库则会给我们自动地划分事务,对于MySQL来说,没有显示声明事务,则一条SQL语句就是一个事务,执行完便会自动提交。 一个事务由开始标识(begin_transaction)、数据库操作和结束标识(commit或rollback)三部分组成。如下图所示: 关于上图的相关说明如下: 事务开始:begin_transaction,说明事务的开始; 数据库上的操作:表现为一条或多条SQL语句; 事务提交:commit_transaction,提交事务操作,操作生效; 事务回滚:rollback_transaction,事务取消,操作废弃。 特性 事务是对数据库的一系列操作,是保证数据库正确性的基本逻辑单元

I'm having an application with an interactive canvas and want to save changes on it, before the user exits the page. My approach function saveBeforeUnload(){ if (confirm('Do you want to save the current state to clipboard?')) { /*yes*/ if (canvas.getObjects("rect").length > 0){ localStorage.setItem("clipboard_unfinishedconfig", JSON.stringify(canvas.toJSON(customProperties))); return; /*no:*/ } else { localStorage.setItem("clipboard_unfinishedconfig", ""); return; } } I call it by window.onbeforeunload = saveBeforeUnload; What I need to accomplish is a yes/no confirmation, if the user wants to

Chrome dismisses confirm() promps immediately without any user interaction

Some users of our website report that confirm dialog boxes appear, but immediately disappear, as if they are being dismissed automatically. This appears to be affecting Chrome only, not other browsers (not even Chromium). Searching for similar issues finds many people complaining about confirm dialogs within onbeforeunload , but that is not my issue: this is not in that situation. The confirm dialog is shown when the page initially loads (triggered by jQuery $(document).ready() ). The Chrome documentation shows that confirm will not activate its tab and will be dismissed when the tab is
