Object creationIt is very easy to create a class in javascript:var myObject = { , function() { alert (this . AVar);} }You do not have to create an object by defining a class and then instantiating the

This blog is reproduced in: http://devbean.javaeye.com/blog/406265 Class is one of the core concepts of object-oriented programming.

To set the style of an element by using the ClassName property: The id= "P1" element is added to the "class name one" style by classname.

But there is no class concept in JavaScript, the so-called class is also simulated, through the function of the closure to simulate the class members and private members (for closures can see crossing boundaries: Closures)。 Here we will look at the "class" in

In small projects for JavaScript use, just write a few function on the line. But in large projects, especially in the development of the pursuit of a good user experience of the site, such as SNS, will use a lot of javascrpt, sometimes JavaScript workload than C #, then write a bunch of function, it will appear very messy, disorganized, even a naming conflict, It's cumbersome to manage and maintain. In this

do is often incredible, and some functions can even be equivalent to the desktop program. Now we can start with a javascript development framework prototype_1.3.1 (prototype. I would like to introduce the advanced javascript applications first, but I am afraid that the level is not enough and that it is not organized. Therefore, combined with prototype, I will mention js syntax usage by the way. The follo

These years have focused on project management, with fewer codes. These days more idle, want to the original experience precipitation down, one is to do a good record, later if you forget to get back as soon as possible, the second is to write a blog, is to practice writing it.In this case, the JavaScript class library was written. As we all know, Javacript is a very interesting language. Although it is the

desktop program. Now we can start with a javascript development framework prototype_1.3.1 (prototype. I would like to introduce the advanced javascript applications first, but I am afraid that the level is not enough and that it is not organized. Therefore, combined with prototype, I will mention js syntax usage by the way.The following is the first two pieces of code in the framework: Var Prototype = {Ver

In daily website development and web application development, we often need to effectively call functions related to date and time formats for Javascript processing, javascript contains some of the most basic built-in processing methods. Of course, if you have time, you can develop and compile the required methods by yourself. However, it is certainly a better way to effectively use the

enrich your JavaScript class libraryEvery good developer will form its own class library, and as a Java developer, we will also write a bunch of tool classes to simplify our development efforts. But as a full station siege lion, not only to understand the formation of Java class Library,

comparable to desktop programs. Okay, no more nonsense, now start with a JavaScript development framework prototype_1.3.1 (hereinafter referred to as prototype). I originally wanted to introduce the advanced application of JavaScript, but afraid of the level is not enough, said the lack of organized, so on the combination of prototype, the way will mention the use of JS Grammar. Here is the first two para

This article takes the previous JavaScript object-oriented programming (1) Foundation. As mentioned in the previous article, JavaScript does not have a class concept and needs to implement the definition of classes through functions. Let's take an example to illustrate: Copy Code code as follows: function MyClass () { var id = 1; var name =

function is used in JavaScript to create functions or methods, but to implement object-oriented programming, classes are one of the indispensable roles and protagonists. But there is no class concept in JavaScript, and the so-called class is also simulated, and the class mem
