Create/open IndexedDB database
// IndexedDB
window.indexedDB = window.indexedDB || window.webkitIndexedDB || window.mozIndexedDB || window.OIndexedDB || window.msIndexedDB,
IDBTransaction = window.IDBTransaction || window.webkitIDBTransaction || window.OIDBTransaction || window.msIDBTransaction,
dbVersion = 1;
Note: The recommended way to do this is assigning it to window.indexedDB,
to avoid potential issues in the global scope when web browsers start
removing prefixes in their implementations.
You can assign it to a varible, like var indexedDB… but then you have
to make sure that the code is contained within a function.
// Create/open database
var request ="elephantFiles", dbVersion);
request.onsuccess = function (event) {
console.log("Success creating/accessing IndexedDB database");
db = request.result;
db.onerror = function (event) {
console.log("Error creating/accessing IndexedDB database");
// Interim solution for Google Chrome to create an objectStore. Will be deprecated
if (db.setVersion) {
if (db.version != dbVersion) {
var setVersion = db.setVersion(dbVersion);
setVersion.onsuccess = function () {
else {
else {
// For future use. Currently only in latest Firefox versions
request.onupgradeneeded = function (event) {
