    IDBDatabase.version

    This article is in need of a technical review.

    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.

    Syntax

    db.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);
    };
