<h3> What is XmlHttp? </h3> <p> The most common definition is: XmlHttp is a set of APIs that can transmit or receive XML and other data through the http protocol in JavaScript, VbScript, Jscript and other scripting languages. The biggest use of XmlHttp is that it can update part of the content of a web page without refreshing the entire page. <br /> Explanation from MSDN: XmlHttp provides a protocol for the client to communicate with the http server. The client can send requests to the http server through the XmlHttp object (MSXML2.XMLHTTP.3.0) and use the Microsoft XML Document Object Model Microsoft® XML Document Object Model (DOM) handles responses. </p> <p> Most of the current browsers have added support for XmlHttp. IE uses ActiveXObject to create XmlHttp objects. Other browsers such as Firefox and Opera use window.XMLHttpRequest to create xmlhttp objects.​ </p>

JavaScript was once "the most misunderstood language in the world" because it was burdened with too many features, including poor interaction and failed design. But with the advent of Ajax, JavaScript "evolved from the most misunderstood programming language to the most popular." "Language", this is not only lucky, but also proves that it is actually an excellent language. In this book, Douglas Crockford peels off the tainted coat of JavaScript and extracts a subset of JavaScript with better reliability, readability, and maintainability, allowing you to see an elegant, lightweight language. and very expressive language. The author presents the real essence of this language from 9 aspects: syntax, objects, functions, inheritance, arrays, regular expressions, methods, styles and beautiful features, through which elegant and efficient code can be constructed. The author also lists the bad and useless parts of the language in the appendix and tells you how to avoid them. Finally, JSLint is introduced. Through its inspection, we can effectively protect the quality of our code.​

The book starts from the various components of JavaScript language implementation - language core, DOM, BOM, event model, and discusses object-oriented programming, Ajax and Comet server-side communication, HTML5 forms, media, Canvas (including WebGL) and WebWorkers in a simple and easy-to-understand manner. , geolocation, cross-document messaging, client-side storage (including IndexedDB) and other new APIs, it also introduces offline applications and best development practices related to maintenance, performance, and deployment.

If you have just started learning web page production and don't know what table layout, html and css are, it is recommended that you recharge your batteries first, otherwise you will have a hard time learning this tutorial or you will not understand it at all. Due to time constraints, this tutorial only explains some basic knowledge, allowing you to move from the original table layout to <br /> Web standard (div css) layout will use web standards to create common pages, which also achieves the purpose of this tutorial. This tutorial is mostly explained step by step in the form of examples. The key points or difficulties involved in the examples will be explained, and the concepts will be less explained. Because concepts are difficult to explain clearly, or even if you explain them clearly, you may not be able to understand them, and even if you understand them, you may not be able to understand them. So I leave the concept to everyone to study in depth later<br /> </p> </div> </div>

Bootstrap is one of the most popular and popular web front-end development frameworks in the world. Its power lies in its complete and complete encapsulation of common CSS layout widgets and JavaScript plug-ins, allowing inexperienced front-end engineers and back-end development engineers to quickly master and use it, greatly improving development efficiency. In addition, it can also standardize the writing of CSS and JavaScript by front-end teams to some extent. <br /> Bootstrap updates relatively quickly, and currently the only two books in China are out of date. This book is written based on the latest version of Bootstrap. It is aimed at two types of readers at the same time: junior front-end development engineers without Bootstrap experience. The detailed explanation of Bootstrap functional components and the display of a large number of cases in the book can help them quickly advance to the mid-to-high-end level; professional front-end development engineers with certain Bootstrap experience. The book's elaboration of Bootstrap architectural ideas, analysis of implementation principles, expansion and secondary development of plug-ins enable them to easily solve various difficult problems encountered during development.

First of all, we need to have basic knowledge of HTML/HTML5 and CSS/CSS3 (you can simply cut pictures). It would be better if you can understand some JS. <br /> Secondly, we need to understand some basic concepts. Otherwise, it will be embarrassing if we go out to brag and cannot understand what others are saying, or if we say it ourselves, it is a very obvious mistake. In order to brag confidently, let us understand the following basic concepts. Bar. <br /> Mobile web development <br /> Pages that perform well on the mobile terminal, such as Sina.com, Tencent News Network, and Phoenix Mobile, also perform well on the mobile terminal. <br /> Mobile web app development <br /> To put it simply, it means using some browser-private methods during development to make the web page have some native functions. Or there are more similar web apps such as mobile Taobao, mobile Meituan, mobile Weibo, etc. They do not obviously use some native functions, but interactive and designed web pages similar to apps must rely on browsers to view them. of. Of course, the industry has recently launched various forms of app/webapp-like application technologies, such as the well-known WeChat applet, PWA launched by Google (obtaining the same permissions as Android native applications), and streaming applications launched by DCloud (obtaining W3C and Supported by domestic mobile phone manufacturers), etc. <br /> hybrid app development <br /> Also called [shell development], simply speaking, it is to generate a cross-platform web app by writing specific code, similar to react native, phonegap, cocos2d, etc. You can use some front-end native development frameworks or package and generate apps based on mobile web pages. <br />
