Extjs4의 toast 효과

Ext.toast = function(){
    var msgCt;
    function createBox(t, s){
       return '
' + t + '
' + s + '
';
    }
    return {
        msg : function(title, format){
            if(!msgCt){
                msgCt = Ext.DomHelper.insertFirst(document.body, {id:'msg-div'}, true);
            }
            var s = Ext.String.format.apply(String, Array.prototype.slice.call(arguments, 1));
            var m = Ext.DomHelper.append(msgCt, createBox(title, s), true);
            m.hide();
            m.slideIn('t').ghost("t", { delay: 1000, remove: true});
        },
              
        init : function(){
            if(!msgCt){
                // It's better to create the msg-div here in order to avoid re-layouts
                // later that could interfere with the HtmlEditor and reset its iFrame.
                msgCt = Ext.DomHelper.insertFirst(document.body, {id:'msg-div'}, true);
            }
        }
