First, you create an instantiated object for the parent class, and then assign the object to the prototype property of the subclass.
In this way, all public instance members in the parent class inherit from the quilt class. And when judged with the instanceof operator, the instantiated object of the subclass belongs to

object creation methods.
1. Original Method
Because object attributes can be dynamically defined after an object is created, many developers write code similar to the following when JavaScript is first introduced:
Var Car = new Object (); Car. color = "blue"; Car. doors
The object model in JavaScript is not widely known. I once wrote a blog about them. JavaScript is the only language widely used to inherit from prototype. However, I think another reason is that this object model is very complex and difficult to explain. Why is it so complicated and confusing? That's because JavaScript tries to hide its traditional object-oriente
Use JavaScript to create new style sheets and new style rules, JavaScript style sheets
In this age, the popularity of Web pages using a lot of JavaScript, we need to find a variety of ways to optimize them, make them faster. We use event delegates to make event listeners more efficient, use frequency reduction techniques to limit the number of uses of certain me
parentheses, where the parentheses function is to correct the JS parser, and do not take the point at the back of the 1 as a decimal. The internal implementation, as described above, is to 1. Use the wrapper object to convert to an object and then call the method.

The object model in JavaScript is not widely known. I have written a blog about them. One reason why it is not well known is that JavaScript is the only one of these widely used languages that is inherited through a prototype (prototype).

There are many ways you can capture a style sheet and add new style rules to it.
Create a new style sheet
Most of the time, the best way is to create a new style element that dynamically adds rules to it. Very simple
While the object constructor or object literal can be used to create a single object, the disadvantage is obvious: creating many objects with the same interface produces a lot of duplicate code.Factory mode1 function Createperson (name,age,job) {2 var o=new
Create an Image object:var a=new image (); Defines the src: a.src= "Xxx.gif" of the image object; This is equivalent to caching a picture for the browser.Image object:Build Image object: Image Object name =new images ([width],[he

1. Question:
C ++ rtti lacks some runtime information and cannot directly create an object based on the object name. To achieve serialization, MFC constructs its own rtti information from the ground up and defines a set of macros. For details, refer to the implementation of the following classes and Macros in the MFC source generation:Cruntimeclass, cobject, decl
Object--function Special DescriptionIn JS, everything is an object.
Class (Prototype object) is actually an object, it is actually an instance of the function class, through which we can create our own object instances, which ca
, which is not conducive to the reuse of code, but also to the user's choice.
With this in mind, I detached the "Performance" section of window to create renderer,renderer responsible for rendering the content in window so that it could be developed using a series of renderer and a series of window combinations. Using combinations rather than inheritance is also an object oriented principle.
