对象的构造函数或init函数

Question

我正在寻找以下情况的构造函数或init函数:

var Abc = function(aProperty,bProperty){
   this.aProperty = aProperty;
   this.bProperty = bProperty;
}; 
Abc.prototype.init = function(){
   // Perform some operation
};

//Creating a new Abc object using Constructor.

var currentAbc = new Abc(obj,obj);

//currently I write this statement:
currentAbc.init();

新对象初始化时有没有办法调用init函数？

Answer 1

你可以init()从构造函数调用

var Abc = function(aProperty,bProperty){
   this.aProperty = aProperty;
   this.bProperty = bProperty;
   this.init();
};

也许是这样的？

var Abc = function(aProperty,bProperty){
    this.aProperty = aProperty;
    this.bProperty = bProperty;
    this.init = function(){
        // Do things here.
    }
    this.init();
}; 
var currentAbc = new Abc(obj,obj);

如果你的init方法应该保密:

var Abc = function(aProperty,bProperty){
   function privateInit(){ console.log(this.aProperty);}   
   this.aProperty = aProperty;
   this.bProperty = bProperty;

   privateInit.apply(this);
};

我更喜欢这个.
