commit() 方法在 IDBTransaction interface commits the transaction if it is called on an active transaction.

注意， commit() doesn't normally have to be called — a transaction will automatically commit when all outstanding requests have been satisfied and no new requests have been made. commit() can be used to start the commit process without waiting for events from outstanding requests to be dispatched.

If it is called on a transaction that is not active, it throws an InvalidStateError DOMException .

注意： 此特征可用于 Web 工作者 .

句法

transaction.commit();

参数

None.

Void.

范例

// open a read/write db transaction, ready for adding the data
var transaction = db.transaction(["myDB"], "readwrite");
// report on the success of opening the transaction
transaction.oncomplete = function(event) {
  note.innerHTML += '<li>Transaction completed: database modification finished.</li>';
};
transaction.onerror = function(event) {
  note.innerHTML += '<li>Transaction not opened due to error. Duplicate items not allowed.</li>';
};
// create an object store on the transaction
var objectStore = transaction.objectStore("myObjStore");
// add our newItem object to the object store
var objectStoreRequest = objectStore.add(newItem[0]);
objectStoreRequest.onsuccess = function(event) {
  // report the success of the request (this does not mean the item
  // has been stored successfully in the DB - for that you need transaction.onsuccess)
  note.innerHTML += '<li>Request successful.</li>';
};
// Force the changes to be committed to the database asap
transaction.commit();
