JavaScriptでは構造関数を使って継承コードを実現します.

 
  
//       
  
function Person(name, age, address) { 
  
this.name = name; 
  
this.age = age; 
  
this.address = address; 
  
} 
  
//     
  
function Student(score) { 
  
this.score = score; 
  
//   call     apply            
  
//         ，  call    Person      。     student    Person  ，student    Person       
  
Person.call(this,"zhangsan",22,"    ！"); 
  
} 
  
 
  
var student = new Student(100); 
  
alert(student.address + student.score + " ");
