Examples
Using addEventListener()
:
// Open the database const DBOpenRequest = window.indexedDB.open('toDoList', 4); DBOpenRequest.onupgradeneeded = event => { const db = event.target.result; db.onerror = () => { console.log('Error creating database'); }; // Create an objectStore for this database var objectStore = db.createObjectStore('toDoList', { keyPath: 'taskTitle' }); // define what data items the objectStore will contain objectStore.createIndex('hours', 'hours', { unique: false }); objectStore.createIndex('minutes', 'minutes', { unique: false }); objectStore.createIndex('day', 'day', { unique: false }); objectStore.createIndex('month', 'month', { unique: false }); objectStore.createIndex('year', 'year', { unique: false }); }; DBOpenRequest.onsuccess = event => { const db = DBOpenRequest.result; // open a read/write db transaction, ready for adding the data const transaction = db.transaction(['toDoList'], 'readwrite'); // add a listener for `complete` transaction.addEventListener('complete', event => { console.log('Transaction was completed'); }); const objectStore = transaction.objectStore('toDoList'); const newItem = { taskTitle: 'my task', hours: 10, minutes: 10, day: 10, month: 'January', year: 2019 }; const objectStoreRequest = objectStore.add(newItem); };
Using the oncomplete
property:
// Open the database const DBOpenRequest = window.indexedDB.open('toDoList', 4); DBOpenRequest.onupgradeneeded = event => { const db = event.target.result; db.onerror = () => { console.log('Error creating database'); }; // Create an objectStore for this database var objectStore = db.createObjectStore('toDoList', { keyPath: 'taskTitle' }); // define what data items the objectStore will contain objectStore.createIndex('hours', 'hours', { unique: false }); objectStore.createIndex('minutes', 'minutes', { unique: false }); objectStore.createIndex('day', 'day', { unique: false }); objectStore.createIndex('month', 'month', { unique: false }); objectStore.createIndex('year', 'year', { unique: false }); }; DBOpenRequest.onsuccess = event => { const db = DBOpenRequest.result; // open a read/write db transaction, ready for adding the data const transaction = db.transaction(['toDoList'], 'readwrite'); // add a listener for `complete` transaction.oncomplete = event => { console.log('Transaction was completed'); }; const objectStore = transaction.objectStore('toDoList'); const newItem = { taskTitle: 'my task', hours: 10, minutes: 10, day: 10, month: 'January', year: 2019 }; const objectStoreRequest = objectStore.add(newItem); };
