The maintenance of JavaScript code in front-end development is always a headache, especially in rich client applications, it is necessary to write a very large JavaScript code, although JavaScript claims to be an object-oriented language, however, the support for inheritance and strong types in Modern Languages is very

is just the time Oh! Oh! So here is also a lesson to you, buy JavaScript books, it is best not to buy 4 years ago, that is, 2005 ago published. It's best to buy books published nearly two years ago. Here, I want to talk about a phenomenon, with this people in recent years to the importance of JavaScript and research, mainly many traditional programmers began to learn and study

Use Modello to write JavaScript classes From: http://www.ajaxwing.com/index.php? Id = 2 I. background Looking back at the development of programming languages, it is not difficult to find that this is a process of continuous encapsulation: From the first assembly language, to the process-oriented language, and then to the object-oriented language, the scripting language with object-oriented features is fu

important aspect is the user experience. A good user experience not only requires the artist to do well, but also emphasizes the response speed and dynamic effect. Many famous web2.0 apps use a lot of JavaScript code, such as Flickr, Gmail, and so on. Even some people use Javasript to write browser-based GUIs, such as Backbase, Qooxdoo, and so on. So the development and maintenance of

You have to decide which of these two ways to write your JavaScript, and in order to help you make informed decisions about which is more appropriate for you, we will compare the pros and cons of these two methods. One disadvantage of using JavaScript libraries in the past is that libraries tend to be quite large, perhaps including a lot of code that isn't actua

So I wondered if I could write some simple code to perfect the template engine and work with other existing logic. The Absurdjs itself is primarily published as a Nodejs module, but it also publishes a client version. With that in mind, I can't use the existing engine directly, because most of them run on Nodejs, not in the browser. What I need is a small, purely JavaScript-written thing that can run direct

You must decide which of the two methods to write your JavaScript code. To help you make a wise decision which is more suitable for you, we will compare the advantages and disadvantages of the two methods.One disadvantage of using JavaScript libraries in the past is that libraries are often quite large, and may include a lot of code that is not actually used on y

are just the beginning. The new ignition and turbofan pipelines pave the way for further optimization, which will boost JavaScript performance over the next few years and reduce the share of V8 in chrome and node. js.Finally, here are some tips on how to write well-optimized, better JavaScript. Of course, it is not difficult to get these tips from the above, but

I have discussed writing methods in JavaScript before. Private implementations are not discussed. Read this article. We know that the implementation of private attributes in JS is essentially var + closure. As follows:Copy codeThe Code is as follows:Function Person (n, ){// PublicThis. name = n;// PrivateVar age =;This. getName = function (){Return this. name;}This. getAge = function (){Return age;}}The test is as follows. age is private and cannot be

, the integrity of these strings must be retained during separation. The string is separated into a small string and then spliced with the plus sign. But pay attention to the operator priority. Therefore, all separated strings must be enclosed in parentheses, so that the priority of this plus sign is always the highest.For more information about the algorithm, see splitDoubleQuot in the keep-line.js ). Conclusion Now, the entire application is complete, and the graphic code can be generated fro

JSON (JavaScript Object notation) is a simple data format that is lighter than XML. JSON is the native format of JavaScript, which means that processing JSON data in JavaScript does not require any special APIs or toolkits.The rule of JSON is simple: an object is an unordered set of ' name/value pairs '. An object begins with "{" (opening parenthesis), and "}" (c
