object oriented javascript examples

In object-oriented languages, overloading is an important feature, while JavaScript, a self-proclaimed object-oriented language, does not directly provide overload functions. Let me define it as follows: The Code is as follows: Function getDate (){.....}Function getDate

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 the workload of JavaScript than C #, then write a bunch of function, it will appear very messy, messy, even the naming conflict, Management and maintenance are all very troub

Javascript does not have the namespace concept, but to embody the object-oriented thinking, there should be a namespace, just like the package in java ,. the namespace in. net is used to prevent class name conflicts. The same class name does not conflict as long as it belongs to different namespaces. The simplest way to create a namespace is: The Code is as fol

This section describes the private and public members of JavaScript. Although JavaScript does not have private and public keywords, it is still the same sentence-as developers, we need to have an object-oriented idea! In fact, it is very simple. I believe you will be clear at a glance after reading the following code a

error, we can see that the above method for global variables did not establish a namespace, global variables for us to pose a danger. So the above wording is right, let's verify: Copy Code code as follows: var box = { Width:2, Height:2, Getarea:function () { The access to the object in return This.width*this.height;//js must be displayed, that is, this is not omitted }, Init:function (w,h) { This.width = W; This.height

There is no concept of namespaces in JavaScript, but to embody object-oriented thinking, There should be a namespace, just like the namespace in Package,.net in Java, The main function is to prevent class name conflicts, the same class name as long as the different namespaces, will not conflict.

Some time ago, after learning "ajax self-taught manual", I realized that javascript can still be written like this. I have learned the concepts of classes in java, c #, and vb, and classes have functions such as inheritance, encapsulation, and polymorphism.
