JavaScript使用引入組合模式的方法

 var school=function (name) {
  this.name=name;
  var classes=new Array();
   this.addClasses=function (cla) {
   classes.push(classe);
   }
   this.getClass=function () {

 }

//班級類
 var classes=function (name) {
  this.name = name;
  var groups = new Array();
  this.addGroup = function (group) {
   groups.push(group);
   return this;
  };
  this.getGroups = function () {
   return groups;
  }
 };

 //組
 var group=function (name) {
  this.name=name;
  var students=new Array();
  var addStudents=function (student) {
   students.push(student);
   return this;
  }
   this.geStudent=function () {
    return students;
   }
 };

 //學(xué)生類
  var student=function (name) {
   this.name=name;
   this.gotoClass=function () {
    document.write(name+"：我是學(xué)生，我要去上課 ")
   };
   this.finishClass=function () {
    document.write(name+": 終于下課了");
   }
  };

 //學(xué)生實例

//班級實例(1)
  var class1=new classes("一班");
  //組1

 //學(xué)校實例
 var usSchool=new school("組合模式學(xué)校");

 var classes=usSchool.getClass();//班級
