x = {
aInternal: 10,
aListener: function(val) {},
set a(val) {
this.aInternal = val;
this.aListener(val);
},
get a() {
return this.aInternal;
},
registerListener: function(listener) {
this.aListener = listener;
}
}
Then you can register a listener using the following:
x.registerListener(function(val) {
alert("Someone changed the value of x.a to " + val);
});
