私はデモサンプル "Skate Warehouse"（HTML5/JS DevExtreme）をテストしています。 アプリはProducts.jsのデータをどこから取得しますか？ テキストファイルから情報を読み込み、製品に表示することはできますか？"Skate Warehouse"（HTML5/JS DevExtreme）のデータ管理
Products.js：

window.DXSK8.Store = window.DXSK8.Store || {};
window.DXSK8.Store.db = window.DXSK8.Store.db || {};
(function() {

wheels: "3182DE2E-417D-4B1F-9E6D-1CB073DC5A04"
}
db.loadProduct = function(id, success, fail) {
return DXSK8.db.Products.load({
