Yes, it is. It is tied to the "class object", which is the constructor
function object in JavaScript:
function myWonderfullClass() {
this.countme = ++myWonderfullClass.countme;
}
myWonderfullClass.countme = myWonderfulClass.prototype.countme = 0
myWonderfulClass.alertCount = myWonderfulClass.prototype.alertCount =
function() {
window.alert(this.countme);
};
function callMyFunction(f) { f(); }
// this will alert '0'
myWonderfullClass.alertCount();
myObject = new myWonderfullClass();
// this will alert '1'
myWonderfullClass.alertCount();
// this will alert '1'
myObject.alertCount();
// this will alert '', or 'undefined'
'callMyFunction(myWonderfulClass.alertCount);
// this will alert '', or 'undefined'
'callMyFunction(myObject.alertCount);
this.countme = 42;
// this will alert '42'
'callMyFunction(myWonderfulClass.alertCount);
// this will alert '42'
'callMyFunction(myObject.alertCount);
