[JS] Sencha Touch i zapisywanie danych do pliku - heavy1123 - 13-02-2012

Mam aplikację napisaną na bazie Sencha Touch, w której można tworzyć proste notatki (tytuł + opis), ale ona zapisuje dane do pamięci podręcznej, a chciałbym, żeby zapisywała je do jakiegoś pliku (np. txt czy php). Z góry dzięki za pomoc:

app.js
Kod:

                { name: 'id', type: 'int' },
                { name: 'date', type: 'date', dateFormat: 'c' },
                { name: 'title', type: 'string' },
                { name: 'narrative', type: 'string' }
            ],
            validations: [
                { type: 'presence', field: 'id' },
                { type: 'presence', field: 'title', message: 'Please enter a title for this note.' }
            ]
        });

        Ext.regStore('NotesStore', {
            model: 'Note',
            sorters: [{

            proxy: {
                type: 'localstorage',
                id: 'notes-app-store'
            },
            getGroupString: function (record) {
                if (record && record.data.date) {
                    return record.get('date').toDateString();
                } else {
                    return false;
