Your definition of "static" is what confused me. Why are you calling
shared instance members (where member is property/method) "static"?
Wiki, btw, clearly states that "... a static method cannot refer to a
specific instance of the class (i.e. it cannot refer to this, self,
Me, etc.)..."
http://en.wikipedia.org/wiki/Method_(computer_science)#Static_methods
That's pretty much what I wrote earlier about "static" members as
understood by majority - it's a member of constructor, not
constructor's prototype (as you refer to).
// constructor
function Person(name) {
this.name = name;
Person.count++;
};
// static property (defined directly on a constructor)
Person.count = 0;
// shared instance method
Person.prototype.say = function(message) {
return this.name + ' says: ' + message;
}
Same goes for prototype.js
var Person = Class.create({
// constructor
initialize: function(name) {
this.name = name;
Person.count++;
},
// shared instance method
say: function(message) {
return this.name + ' says: ' + message;
}
});
// static property
Person.count = 0;
