transaction 只读特性在 IDBObjectStore interface returns the transaction object to which this object store belongs.

注意： 此特征可用于 Web 工作者 .

句法

var myTransaction = objectStore.transaction;
					

值

IDBTransaction 对象。

范例

In the following code snippet, we open a read/write transaction on our database and add some data to an object store using add() . After the object store has been created, we log objectStore.transaction to the console. For a full working example, see our 待办通知 app ( 实时查看范例 )。

// Let us open our database
var DBOpenRequest = window.indexedDB.open("toDoList", 4);
DBOpenRequest.onsuccess = function(event) {
  note.innerHTML += '<li>Database initialised.</li>';
  // store the result of opening the database in the db variable.
  // This is used a lot below
  db = DBOpenRequest.result;
  // Run the addData() function to add the data to the database
  addData();
};
function addData() {
  // Create a new object ready to insert into the IDB
  var newItem = [ { taskTitle: "Walk dog", hours: 19, minutes: 30, day: 24, month: "December", year: 2013, notified: "no" } ];
  // open a read/write db transaction, ready for adding the data
  var transaction = db.transaction(["toDoList"], "readwrite");
  // report on the success of the transaction completing, when everything is done
  transaction.oncomplete = function(event) {
    note.innerHTML += '<li>Transaction completed.</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("toDoList");
  console.log(objectStore.transaction);
  // Make a request to add our newItem object to the object store
  var objectStoreRequest = objectStore.add(newItem[0]);
  objectStoreRequest.onsuccess = function(event) {
    // report the success of our request
    note.innerHTML += '<li>Request successful.</li>';
  };
};
