It's easy:
这很简单：
Ob.prototype.add = function(){
this.inc()
}
Ob.prototype.inc = function(){
alert(' Inc called ');
}
When you create the instance of Obproperties from prototype are copied to the object. If you want to access the methods of instance from within its another method you could use this.
当您Ob从原型创建属性实例时，将复制到对象中。如果您想从另一个方法中访问实例的方法，您可以使用this.
