To learn this series of tutorials, you need to have a certain basic knowledge of HTML and CSS, which means you have made web pages before and know how to use table layout. 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. <br /> Due to time constraints, this tutorial only explains some practical knowledge, allowing you to move from the original table layout to the web standard (div css) layout, and use web standards to create common pages, which also achieves the purpose of this tutorial. <br /> 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 you to study in depth later.​

This book is the crystallization of the experience of senior Web technology experts and is a must-have for front-end engineers.

<p> In literal mode, all the contents wrapped between // are metacharacters, some have special meanings, and most of them are ordinary metacharacters that represent their own meaning <br /> varname ='wo';<br /> varreg = /^\d " name "\d $/<br /> In order to solve the above-mentioned need to add a variable to the regular expression, we can only use the instance creation method<br /> varreg =newRegExp("^\\d " name "\\d $","g")<br /> What is the difference between literal method and instance creation method in regular expressions?<br /> 1. Everything that appears in the literal method is metacharacters, so variable values ​​cannot be spliced, but the instance creation method is possible. <br /> 2. Just write \d directly in the literal, but in the example it needs to be translated as \\d<br /> </p>

This book brings together the most useful CSS technologies, summarizes the best practices in CSS design, discusses techniques for solving various practical problems, and fills the gap in CSS books.

Regular expression is a regular expression. It seems that English is much easier to understand than Chinese. Just check the expression symbol <br /> did not qualified! ! Regular expressions have a very powerful and complex object RegExp. In JavaScript version 1.2, it starts with <br /> provided on. <br /> Let’s take a look at the introduction to regular expressions: <br /> Regular expression objects are used to standardize a standardized expression (that is, the expression does not meet specific requirements, such as whether it is Email<br /> address format, etc.), which has properties and methods for checking whether the given string conforms to the rules. <br /> In addition, the properties of individual regular expression objects you create using the RegExp constructor have already predefined regular expressions<br /> Static properties of objects, you can use them at any time.

<p> Regular expressions are a small, highly specialized programming language that is not unique to Python. It is a basic and important part of many programming languages. In python, it is mainly implemented through the re module. </p> <p> Regular expression patterns are compiled into a series of bytecodes and then executed by a matching engine written in C. So what are the common usage scenarios of regular expressions? </p> <p> For example, specify rules for the corresponding set of strings you want to match; </p> <p> The string set can include e-mail addresses, Internet addresses, phone numbers, or some string sets customized according to needs; </p> <p> Of course, you can also judge whether a string set conforms to the matching rules we defined; </p> <p> Find the part of the string that matches the rule; </p> <p> A series of text processing such as modification and cutting; </p>

A relatively new introductory tutorial on AJAX - ExtJS2.0. EXTJS is a front-end AJAX framework that has nothing to do with back-end technology. It can be used to develop WEB applications with gorgeous interfaces and good user experience. At the same time, AJAX technology is also very popular nowadays. A WEB technology, so this entry-level tutorial can let you first understand some basic knowledge of AJAX.

Among the 7 technologies involved in AJAX, I personally think Javascript, XMLHttpRequest, DOM, and XML are more useful. <br /> <a>A</a>、XMLHttpRequest object<br /> XMLHttpRequest is an object of the XMLHTTP component. Through this object, AJAX can only exchange data with the server like a desktop application, without having to refresh the interface every time, and there is no need to hand over the data processing work to the server every time. ; This not only reduces the load on the server, speeds up the response speed, and shortens the user's waiting time. <p> Starting from IE5.0, developers can use XMLHTTP ActiveX components inside Web pages to extend their own functions. They can directly transmit data to the server or receive data from the server without navigating from the current Web page. , Mozilla1.0 and NetScape7 create the proxy class XMLHttpRequest that inherits XML; for most cases, the XMLHttpRequest object is very similar to the XMLHTTP component, with similar methods and properties, but some properties are different. </p>

<p> The ajax() method loads remote data via HTTP requests. </p> <p> This method is the underlying AJAX implementation of jQuery. For simple and easy-to-use high-level implementations, see $.get, $.post, etc. $.ajax() returns the XMLHttpRequest object it created. In most cases you won't need to manipulate this function directly unless you need to manipulate less commonly used options for more flexibility. </p> <p> In the simplest case, $.ajax() can be used directly without any parameters. </p>

With the promotion and application of HTML5 technology in China, browsers gradually support richer HTML5 features, and various HTML5 platforms have emerged, rich in diversified market opportunities. <br /> In 2015, domestic HTML5 platforms mainly provided production and development tools, which were divided into three categories: light marketing templates (such as Yiqixiu), functional engines (such as Bailu) and basic tools (such as iH5). With the gradual development of these platforms, the HTML5 industry has begun to shift from technical application to the benign ecology of the entire industry. <br /> However, there is still huge room for growth in the application of HTML5. In the near future, it is likely to gradually transform from the advertising industry to the gaming industry, radio and television industry, and media industry, and it will also be able to extend its reach further in the near future. As a new generation of web development standards, HTML5 is bound to burn in the coming year. <br /> In the eyes of many people, HTML5 is closely related to Internet marketing, but in fact, from the starting point of its establishment, it is a web page standard that defines the writing specifications of browser languages. As the dust of the HTML5 standard has settled, its powerful web application development capabilities have forced people to change their inherent Internet thinking and find new web solutions.
