Detailed JavaScript _javascript techniques based on object-oriented inheritance instances

A simple example of JavaScript object-oriented inheritance:
As an object-oriented language, inheriting nature is one of its great features, although JavaScript's object-oriented implementation mechanism is different from the typical object-oriented objects of C # and Java, but the basic feature of inheritance is to get the methods and properties of the parent, which is a simple example. We are interested to analyze:

Window.onload = function () { 
 function parent (age,name) { 
  this.age = age; 
  this.name = name; 
 Parent.prototype.show = function () { 
  alert (' parent method '); 
 } 
 function Child (age,name,job) { 
  parent.apply (this,arguments); 
  This.job = job; 
 } 
 (function () {for 
  (var i in Parent.prototype) { 
  child.prototype[i]=parent.prototype[i] 
 } 
 }) (); 
 var B = new Parent (14, ' Knight's Line '); 
 var a = new Child (15, ' Werewolf ', ' Knight '); 
 A.show (); 
}

The above is a simple example of JavaScript object-oriented inheritance, you can combine the previous "detailed JavaScript based on object-oriented inheritance" to study together, may be better results.
