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);
};
