ExtJs Message box sliding of message

Question

I came across this example in extJs. i find that they are using Ext.example.msg for the sliding to happen. So, I have decided to store the file example.js in app/ext/example/example.js

Ext.example = function(){
    var msgCt;

    function createBox(t, s){
        return ['<div class="msg">',
                '<div class="x-box-tl"><div class="x-box-tr"><div class="x-box-tc"></div></div></div>',
                '<div class="x-box-ml"><div class="x-box-mr"><div class="x-box-mc"><h3>', t, '</h3>', s, '</div></div></div>',
                '<div class="x-box-bl"><div class="x-box-br"><div class="x-box-bc"></div></div></div>',
                '</div>'].join('');
    }
    return {
        msg : function(title, format){
            if(!msgCt){
                msgCt = Ext.DomHelper.insertFirst(document.body, {id:'msg-div'}, true);
                debugger;
            }
            msgCt.alignTo(document, 't-t');
            var s = String.format.apply(String, Array.prototype.slice.call(arguments, 1));
            var m = Ext.DomHelper.append(msgCt, {html:createBox(title, s)}, true);
            m.slideIn('t').pause(1).ghost("t", {remove:true});
        },

        init : function(){
            var t = Ext.get('exttheme');
            if(!t){ // run locally?
                return;
            }
            var theme = Cookies.get('exttheme') || 'aero';
            if(theme){
                t.dom.value = theme;
                Ext.getBody().addClass('x-'+theme);
            }
            t.on('change', function(){
                Cookies.set('exttheme', t.getValue());
                setTimeout(function(){
                    window.location.reload();
                }, 250);
            });

            var lb = Ext.get('lib-bar');
            if(lb){
                lb.show();
            }
        }
    };
}();

In index.html I have added the path <script src="./example/example.js" type="text/javascript" ></script>. I keep a debugger inside example.js. It's failing at this ( var s = String.format.apply(String, Array.prototype.slice.call(arguments, 1));) line and displaying the message Uncaught TypeError: Cannot call method 'apply' of undefined. What is this about? I have a save button in my controller and

Ext.MessageBox.alert('Save', 'xxxx', showResult);

function showResult(btn){
    debugger;
    Ext.example.msg('Button Click', 'You clicked the {0} button', btn);
};

What is the new methodology now in ExtJs 4.2. Suggestions please.

It worked. Just need to include the appropriate .css file. The location for the .css file should be specified in index.html or what ever *.html page.
