Example
This example shows a database connection being opened, the resulting IDBDatabase
object being stored in a db variable, and the name property then being logged. For a full example, see our To-do Notifications app (view example live).
// 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 name of the database, which should be "toDoList"
console.log(db.name);
};
