问题 I am displaying a JavaScript confirm box when the user clicks on the "Delete Data" button. I am displaying it as shown in this image: In the image, the "OK" button is selected by default. I want to select the "Cancel" button by default, so that if the user accidentally presses the enter key, the records will be safe and will not be deleted. Is there any way in JavaScript to select the "Cancel" button by default? 回答1: If you can use jQuery plugin then here is a nice one jQuery Impromptu To

问题 My script clicks an image on a site. The image has an anchor href and an onclick href , but the onclick href has a confirm box that pops up once it's clicked. The onclick HTML is: onClick="this.href='link2';if (!confirm('Are you sure?')) { return false; } How do I get the script to click OK in that confirm box, once it pops up? I'm using this function to click the picture link: function click(elm) { var evt = document.createEvent('MouseEvents'); evt.initMouseEvent('click', true, true, window,

分布式事务原理解析

1. 分布式事务原理解析 1.1. TCC分布式事务 了解过TCC分布式事务的都知道它有三个阶段:try,confirm,cancel,但很多文章就只有原理图,和对原理图的解释,看一遍也留不下印象,这里用实际场景举个例子,说明TCC分布式事务原理 try阶段:假设我们又订单系统,它需要调用库存和积分系统,try阶段我们进行的是 预处理 ,比如下单1个商品,在try操作中,我们在库存表设置个冻结字段,表示冻结1个商品,商品的存量先不扣除,而积分表同样添加个预增加积分字段,添加个预积分比如10 confirm阶段: 我们为什么要经历try阶段? ,为了尽可能的保证各个系统都是正常工作的,数据库,服务都没有挂掉,资源没有不足,则可以最大程度上保证confirm阶段能正确执行, confirm阶段也就是正式的扣除库存和增加积分 cancel阶段: 若try阶段执行错误 ,则会对前面已经执行的try阶段的系统执行cancel操作,也就是反向SQL回滚,冻结的商品-1,预积分-10。到这里有没有疑问?我首先想到的是 若confirm或cancel操作再执行失败怎么办 ?这里就要由TCC分布式事务框架保证了,它会 记录事务活动日志 ,再confirm或cancel失败后不断尝试调用confirm和cancel的逻辑,所以这里需要开发者自己保证,你的SQL是正确的 TCC分布式框架推荐

onbeforeunload confirmation screen customization

Is it possible to create a custom confirmation box for the onbeforeunload event in a browser? I tried but then I get 2 confirmation boxes (one from me which is nothing more than return confirm... and then the standard one from the browser). At the moment my code looks like: var inputChanged = false; $(window).load(function() { window.onbeforeunload = navigateAway; $(':input').bind('change', function() { inputChanged = true; }); }); function navigateAway(){ if(inputChanged){ return 'Are you sure you want to navigate away?'; } } I'm using jQuery for this. window.onbeforeunload = function (e) {

bootbox.js官方文档

简介 Bootbox.js 是一个小型的JavaScript库,基于Bootstrap模态框开发,用于创建可编程的对话框。 不像原生的alert等对话框,所有的Bootstrap模态框生成的都是非阻塞事件。所以 在使用 confirm() 对话框时,请记住这一点,因为它不是本地确认对话框的替代。 任何取决于用户选择的代码都必须放在回调函数中。 alert alert是只有单个按钮的对话框,按ESC键或单击关闭按钮可关闭对话框。 bootbox.alert("Your message here…") message中可以放html语言,比如: bootbox.alert("Your message <b>here…</b>") 回调函数: bootbox.alert("Your message here…", function(){ /* your callback code */ }) options选项自定义对话框: bootbox.alert({ size: "small", title: "Your Title", message: "Your message here…", callback: function(){ /* your callback code */ } }) Confirm Confirm是具有确定和取消按钮的对话框,

RabbitMQ事务以及confirm机制

本文是参考下面这篇博客然后进行复现浓缩后的总结 https://www.cnblogs.com/vipstone/p/9350075.html 正常情况下,如果消息经过交换器进入队列就可以完成消息的持久化,但如果消息在没有到达broker之前出现意外,那就造成消息丢失,有没有办法可以解决这个问题?RabbitMQ有两种方式来解决这个问题: 通过AMQP提供的事务机制实现; 使用发送者确认模式实现; 事务使用 事物的实现主要是对于信道(Channel)的设置,其中主要的方法有三个: channel.txSelect()声明启动事务模式; channel.txComment()提交事务; channel.txRollback()回滚事务; 尝试代码实现: public static void main ( String [ ] args ) throws IOException , TimeoutException { ConnectionFactory factory = new ConnectionFactory ( ) ; factory . setUsername ( "guest" ) ; factory . setPassword ( "guest" ) ; factory . setHost ( "localhost" ) ; factory . setPort (

I'm trying to use the jQuery alerts dialog library from http://abeautifulsite.net/notebook/87 instead of the default alerts (which look pretty awful in my opinion). This seems to be a great library, but there is not an example of how to use the jConfirm library. I need to do something like this: function confirm() { var result = false; var response = false; jConfirm('are you sure?', 'Confirmation Dialog', function(r) { result = r; response = true; return r; }); if (response == true) { alert(result); return result; } else { //wait for response alert('hi'); } } and my call from my .net button: I
