IDBDatabase.version

The version property of the IDBDatabase interface is a 64-bit integer that contains the version of the connected database. When a database is first created, this attribute is an empty string.

Note: This feature is available in Web Workers.

Syntax

var myInteger = IDBDatabase.version;

Value

An integer containing the version of the connected database.

Example

// Let us open our database
var DBOpenRequest = window.indexedDB.open("toDoList", 4);

// these two event handlers act on the database
// being opened successfully, or not
DBOpenRequest.onerror = function(event) {
  note.innerHTML += '<li>Error loading database.</li>';
};
 
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;

  // This line will log the version of the connected database, which should be "4"
  console.log(db.version);
};
