function someClass(){
}
someClass.prototype.CONST = 'Some Constant.';
console.log( 'with Obj : '+(new someClass).CONST);
console.log( 'without Obj : '+someClass.CONST);
first one gives right answer, second returns undefined,
now, is there any way to access CONST without creating object instance,
I am looking for something similar to accessing static attributes of Java Class
Yeap, you can access it:
console.log(someClass.prototype.CONST);
You can access all prototypical members via an object's prototype member, not just variables:
// returns a value
someObject.prototype.someMember
// calls the function someFunct()
someObject.prototype.someFunct()
If you need to call a method from one object, using another object as the 'calling instance' you can use .call or .apply
// calls functMember using instanceObject as the instance
someObject.prototype.functMember.call(instanceObject, arg1, arg2, ... );
// calls functMember using isntanceObject as the instance, using an array as arguments
someObject.prototype.functMember.call(instanceObject, [arg1, arg2, ...] );
