问题 I’m trying to get the response of an api request made with ajax.ajax() and the response is stored into ['apiResponse'] in the HTML5 Local Storage (but the rest of the python function processes without waiting for it be put into localStorage). Because of this I need to wait for it before getting the response and I thought I could do what I did below for the program to wait before it proceed. Unfortunately the browser seems to freeze every time I put a while loop... If someone know how to make

How to reload Google Chrome tab from terminal?

由 ぃ、小莉子 提交于 2020-03-17 05:55:09
问题 Is there a way to reload a Google Chrome tab in Ubuntu using just the terminal. I don't want to just open a new window, but to actually refresh a tab! Extra question: Is this possible in other browsers as well such as Opera, Safari, Firefox. 回答1: Looks like user2974830's answer is using some incorrect (perhaps old) syntax for xdotool. --search is supposed to be just search (without the dashes) and --windowid is supposed to be --window That being said here's a more comprehensive solution that

Which browsers have a back-forward cache? (a bfcache keeps modifications to DOM)

由 喜欢而已 提交于 2020-03-16 10:38:51
问题 Which browsers nowadays support a back-forwards cache (bfcache)? A back-forwards cache is a browser's in-memory cache that is used when a user clicks the back button and the forward button. It stores the state of the page as it was when the user navigated away, so any changes made to the DOM should be loaded instantly. Note that this is different from the normal caching mechanisms that all browsers have. A bfcache applies specifically when a user clicks the back button, and can handle dynamic

问题 Is possible to access or acquire the files that are passed to the client from the server, the files displayed on the Network tab in the developer console? I came across this question that suggests obtaining the logs may be possible with browser extension technology, but it is a really old question and answer. I am also interested in obtaining the files, not the logs. Is it possible? 回答1: Yes. you can do it by using Service Workers. Service Worker is a script which runs on your browser

Nodejs 与 javascript 不可通用的原因

1. 三种规范： AMD / CMD / COMMONJS AMD 与 CMD 都属于 COMMONJS 规范，规范提出的目的是为 js 这门松散的语言提供 一致性，标准性 的模块化机制，为开发大型应用，桌面应用，服务后台提供前提。 三种规范分别具有不同的实现， AMD -> requirejs, CMD -> seajs, COMMONJS -> nodejs , 这里只列出比较常见的实现。*** 大体上三种规范重叠性比较大，具体不同请具体查看规范对比 任何上述标准的实现中需要提供 require(), module,module.exports,exports 四个全局对象。 ####2. 一切为了安全： 浏览器 浏览器的与众不同，在于它是一个开放平台式的软件，浏览器只是提供了一些运行环境，而实际的内容贡献者确不是浏览器厂商，为了保证网页发布者的安全，网页浏览者的安全，浏览器不得不限制很多权 限，防止对用户，网页发布者的危害，常见的有： 本地文件操作权限，可执行命令访问权限 等，与网页相关的有 跨域访问限制等。 ####3. 多语言集成 谈到web开发，Html Css Js 算是三个元老级的语言了，其实，从程序的角度来看，html ，css 并不算是一种编程语言，甚至在一定角度上，更像是一种协定好了的配置文件，或者协议栈。所以， 在浏览器中，Js 能够交互的多语言环境

在浏览器里启用混合内容

由 萝らか妹 提交于 2020-02-28 15:54:42
原文同步至 http://waylau.com/mixed-content-blocking-enabled-in-browser/ 本文介绍了在浏览器里什么是混合内容，为什么要禁用混合内容，以及在各种浏览器里面如何启用混合内容。 什么是混合内容 HTTP 是一种从网页服务器将信息传递到您的浏览器的系统。HTTP 并不是安全的，所以当您访问一个通过 HTTP 提供的页面时，您的连接正面临窃听和中间人攻击的风险。大多数网站都使用 HTTP 提供服务，因为它们不涉及敏感信息的传输，因而无需采取加密措施。 当您访问一个完全通过 HTTPS 提供的页面时（例如银行服务），您将看到地址栏中有绿色挂锁图标（详见站点标识按钮）。这表示您的连接经过身份验证和加密，从而防止窃听和中间人攻击。 但是，如果您访问的 HTTPS 页面中含有 HTTP 内容，即使页面主体内容以 HTTPS 提供，HTTP 的部分仍然可被攻击者读取和篡改。当某个 HTTPS 页面含有 HTTP 内容时，我们称它为“混合内容（Mixed Content）”。这种页面仅被部分加密，尽管有些人认为这样是安全的，但事实并非如此。 为啥要禁用混合内容 上面其实已经讲到了。由于混合内容中 HTTP 的部分会对安全造成威胁，所以各大浏览器厂商都会禁用混合内容。 比如，你有一个 HTTPS 的应用，恰巧应用里面调用了一个第三方的 HTTP

问题 In Vaadin Flow, such as version 14.1, how can I get the IP address of the user’s web browser through a Java call on the server-side? Like the Question, Get user’s IP address, and other client-side info in Vaadin 7 web app, but for Vaadin Flow instead of Vaadin 7 & 8. 回答1: WebBrowser::getAddress In Vaadin Flow, use the class WebBrowser::getAddress to get the user's IP address. To get a WebBrowser object, ask the current VaadinSession object. String ipAddress = VaadinSession.getCurrent()
