                                  id:'day2',

                                    labelWidth: '90%',
                                 },

                                                   ]
                                    },      
                                    ]
                             },
                                                        },  

Answer 1

Ext.ComponentQuery.query("checkboxfield{isChecked()}"); should return all checkbox fields.

I think you should know what to do then.

Update: if you don't want to process each single checkbox field, it's easy to do it programmatically, like this:

for (var i=1;i<=3;i++){
    (function(index){
        var id = 'day' + index.toString();
        var component = Ext.getCmp(id);
        localStorage.setItem(id, component.getValue());
    }(i);
}

getting values from localstorage programmatically is similar.
