JavaScript class inheritance and instantiation methods_javascript skills

The examples in this article describe the methods of JavaScript class inheritance and instantiation. Share it with everyone for your reference. The details are as follows:

(function(){
  var Class = {
    //扩展类
    create: function(aBaseClass, aClassDefine){
      var $class = function(){
        for(var member in aClassDefine){
          this[member] = aClassDefine[member];
        }
        if('undefined'===typeof aClassDefine.initialize){
          this.initialize = function(){};
        }
      };
      if('function' ===typeof aBaseClass){        
        $class.prototype = new aBaseClass();        
      }else if('object' ===typeof aBaseClass){
        $class.prototype = aBaseClass;
      }    
      return $class;
    },
    //实例化类
    new: function(jclass,args){
      var jclass = new jclass();
      if(jclass.initialize){
        jclass.initialize.apply(jclass, args);
      }
      return jclass;
    }
  };
  //export
  window.Class = Class;
})();

Example:

//基类对象或函数
var obj = {
  name: 'BaseName',
  init: function(){
    //...  
  },
  //...
};
var fun = function(){
  this.name = '';
  var init = function(){
    //..  .
  };
  var getName = function(){
    return this.name;
  },
  var setName = function(name){
    this.name = name;
    return this;//链式操作支持
  },
  //...
};
//从Object继承
var class_frome_obj = Class.create(obj,{
  initialize: function(){
    //构造函数
  },
  getName: function(){
    return this.name;
  },
  setName: function(name){
    this.name = name;
    return this;//链式操作支持
  },
  //...
});
//从Function继承
var class_frome_fun = Class.create(fun,{
  initialize: function(){
    //构造函数
  },
  //...
});
//从空对生成基类
var class_frome_base = Class.create({},{
  initialize: function(){
    //构造函数
  },
  //...
});
//实例化
var get_class_frome_obj = Class.new(class_frome_obj,[arg1,arg2,...]);
var get_class_frome_fun = Class.new(class_frome_fun,[arg1,arg2,...]);
var name1 = get_class_frome_obj.getName();
//console.log(name1);//BaseName
var name2 = get_class_frome_obj.setName('NewName').getName();
//console.log(name2);//NewName

I hope this article will be helpful to everyone’s JavaScript programming design.
