Sample code of Chain in Official Doc not working?

[Chris Jiang]

Hi guys, basically, I'm trying to implement an standalone chain controller to my project, but the official sample code seems not working, and I can't find why. How should I create a set of functions to be executed one after each? @@"

    var Todo = new Class({
        Implements: Chain,
        initialize: function(){
            this.chain.apply(this, arguments);
        }
    });
 
    var myTodoList = new Todo(
        function(){ alert('get groceries'); },
        function(){ alert('go workout'); },
        function(){ alert('code mootools documentation until eyes close involuntarily'); },
        function(){ alert('sleep'); }
    );

You could of course use .callChain()

I normally do something like this:

new Chain().chain(
    function(){ alert('get groceries'); this.callChain(); },
    function(){ alert('go workout'); this.callChain(); },
    function(){ alert('code mootools...'); this.callChain(); },
    function(){ alert('sleep'); this.callChain(); }
).callChain();

We still had this here:
it starts immediately.

var Todo = new Class({
Implements: Chain,
initialize: function() {
this.chain.apply(this, arguments);

this.callChain();

}
});

var myTodoList = new Todo(

function() {...
alert('get groceries');
this.callChain.delay(500, this);

}, function() {
alert('go workout');

this.callChain.delay(3000, this);

}, function() {
alert('code mootools...');

this.callChain.delay(500, this);

}, function() {
alert('sleep')
}
);

Thank you all for replying. I've solved this and found it's a logic problem I got confused with how it works. Cheers!
