Using var for privates seems like a nice idea at first, but it's rather a "superprivate" since you only have the var in the scope of the concurrent function (like always in javascript) which makes it rather useless unless you declare the methods in the constructor otherwise none of your methods can use it:

function Registry()
{
var somestuff = '123abc';

this.get = function() {
return somestuff;
}
}

var reg = new Registry();
alert(reg.get()); ]]> http://www.phpdevblog.net/2009/09/oop-in-javascript-part-1-writing-classes.html#comment4731 http://www.phpdevblog.net/2009/09/oop-in-javascript-part-1-writing-classes.html#comment4731 Vlad Dumitrica Tue, 15 Sep 2009 10:54:10 +0000
I'd rather go with encapsulation, so I prefer something like this (a variant of Paul's "Three" version):
Test = function(){
var privateData = {
appVersion: '0.1 alpha'
};

var publicData = {
getVersion: function(){
return (privateData.appVersion);
}
};

return publicData;
}(); ]]> http://www.phpdevblog.net/2009/09/oop-in-javascript-part-1-writing-classes.html#comment4739 http://www.phpdevblog.net/2009/09/oop-in-javascript-part-1-writing-classes.html#comment4739 Marcus B Tue, 15 Sep 2009 14:09:05 +0000
The Bindows model does not use encapsulation, instead relying on conventions for property accessors and public/private members. ]]> http://www.phpdevblog.net/2009/09/oop-in-javascript-part-1-writing-classes.html#comment16784 http://www.phpdevblog.net/2009/09/oop-in-javascript-part-1-writing-classes.html#comment16784 shaffy Fri, 13 Aug 2010 05:20:35 +0000
