Question

Please look at my required JavaScript.

var someVariable = new SomeDataType();

// I can directly access value of its property.
someVariable.someProperty = "test";
alert(someVariable.someProperty); // <- this command must should "test"

// However, I have some methods in above property

// I want to validate all rule in this property.
someVariable.someProperty.isValid(); // <- this method will return true/false

Is it possible for doing this in current version of JavaScript?

UPDATE

Please look as my answer!

You can’t (and probably shouldn’t) treat objects like that in JavaScript. As someone else mentioned, you can override the toString() method to get half of the functionality (the read portion), but you cannot use the assignment operator on an object like that without overwriting the object.

You should choose a different approach, like using nested objects (as CMS suggested).
