Examples

This example opens a database (creating the database if it does not exist), then opens a transaction, adds a listener to the abort event, then aborts the transaction to trigger the event.

// Open the database
const dBOpenRequest = window.indexedDB.open('toDoList', 4);

dBOpenRequest.onupgradeneeded = (event) => {
  const db = event.target.result;

  // Create an objectStore for this database
  const 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;

  db.addEventListener('abort', () => {
    console.log('Transaction aborted');
  });

  // open a read/write db transaction, ready for adding the data
  const transaction = db.transaction(['toDoList'], 'readwrite');

  // abort the transaction
  transaction.abort();
};

The same example, but assigning the event handler to the onabort property:

// Open the database
const dBOpenRequest = window.indexedDB.open('toDoList', 4);

dBOpenRequest.onupgradeneeded = (event) => {
  const db = event.target.result;

  // Create an objectStore for this database
  const 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;

  db.onabort = () => {
    console.log('Transaction aborted');
  };

  // open a read/write db transaction, ready for adding the data
  const transaction = db.transaction(['toDoList'], 'readwrite');

  // abort the transaction
  transaction.abort();
};
