The newVersion
read-only property of the IDBVersionChangeEvent
interface returns the new version number of the database.
Note: This feature is available in Web Workers.
Syntax
var newVersion = IDBVersionChangeEvent.newVersion
Value
Example
In the following code snippet, we make a request to open a database, and include handlers for the success and error cases. These events are fired via the custom IDBVersionChangeEvent
interface. For a full working example, see our To-do Notifications app ([[../../../../../../../mdn.github.io/to-do-notifications/index|view example live]].)
var note = document.querySelector("ul"); // In the following line, you should include the prefixes of // implementations you want to test. window.indexedDB = window.indexedDB || window.mozIndexedDB || window.webkitIndexedDB || window.msIndexedDB; // DON'T use "var indexedDB = ..." if you're not in a function. // Moreover, you may need references to some window.IDB* objects: window.IDBTransaction = window.IDBTransaction || window.webkitIDBTransaction || window.msIDBTransaction; window.IDBKeyRange = window.IDBKeyRange || window.webkitIDBKeyRange || window.msIDBKeyRange; // (Mozilla has never prefixed these objects, // so we don't need window.mozIDB*) // Let us open version 4 of our database var DBOpenRequest = window.indexedDB.open("toDoList", 4); // these two event handlers act on the database being opened 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 later on, for opening transactions and suchlike. db = DBOpenRequest.result; };
