Management of this in javascript

[Thomas]

hello

I have a problem with the following code :

var Test = Class.create({
data:"Test",
initialize: function() {
this.t2 = new Test2(this.callt1);
},
callt1: function(){
alert(this.data);
}

});

var Test2 = Class.create({
data: "Test2",
initialize: function(callback) {
this.callback=callback;
},
callt2: function(){
this.callback();
}

});

var t = new Test();

t.t2.callt2();

I get "Test2" but I'm wait for "Test". I think it is not a bug but how
can I do to obtain "Test"

That's quite confusing : )

You obtain "Test" like so:
t.t2.callback.call(t)

Wow, is this a test?

You can also get "Test" by binding your callback to Test

var Test = Class.create({
data:"Test",
initialize: function() {

this.t2 = new Test2(this.callt1.bind(this));

},
callt1: function(){
alert(this.data);
}

});
