Hi, I'm just trying to use the Indexed Database Api, looking on web i found a simple code to test this api.
I've changed a lot of the original code to adapt it to my needs, and now i've a problem.
If i try to run the code on Chromium (v 23.0.1264.0 (156235)) it works really fine, but if i try the same code on Chrome (v 21.0.1180.89 m) it gives me a NotFoundError: DOM IDBDatabase Exception 8.
I'm using this script :
var indexedDB = window.indexedDB || window.webkitIndexedDB || window.mozIndexedDB || window.msIndexedDB;
var IDBTransaction = window.IDBTransaction || window.webkitIDBTransaction;
var db;
(function () {
function initDb() {
var request = indexedDB.open("UsersDB", 1);
request.onsuccess = function (evt) {
db = request.result;
};
request.onerror = function (evt) {
console.log("IndexedDB error: " + evt.target.errorCode);
};
request.onupgradeneeded = function (evt) {
var objectStore = evt.currentTarget.result.createObjectStore("users", { keyPath: "id", autoIncrement: true });
objectStore.createIndex("name", "name", { unique: false });
objectStore.createIndex("email", "email", { unique: true });
};
}
function contentLoaded() {
initDb();
var btnAdd = document.getElementById("btnAdd");
var btnDelete = document.getElementById("btnDelete");
var btnPrint = document.getElementById("btnPrint");
var btnClear = document.getElementById("btnClear");
btnAdd.addEventListener("click", function () {
var name = document.getElementById("txtName").value;
var email = document.getElementById("txtEmail").value;
var transaction = db.transaction(["users"], "readwrite");
var objectStore = transaction.objectStore("users");
var request = objectStore.add({ name: name, email: email });
request.onsuccess = function (evt) {
console.log("Record added!");
};
}, false);
btnDelete.addEventListener("click", function () {
var id = document.getElementById("txtID").value;
var transaction = db.transaction(["users"], "readwrite");
var objectStore = transaction.objectStore("users");
var request = objectStore.openCursor();
request.onsuccess = function(evt) {
var cursor = evt.target.result;
if (cursor) {
if(cursor.key == id){
var delReq = objectStore.delete(cursor.key);
delReq.onsuccess = function(evt){
console.log("Deleted!");
}
delReq.onerror = function(evt){
console.log("Not Deleted!");
}
}
cursor.continue();
}
};
request.onerror = function(evt){
console.log("Error!");
};
}, false);
btnPrint.addEventListener("click", function () {
var output = document.getElementById("printOutput");
output.textContent = "";
var transaction = db.transaction(["users"], "readonly");
var objectStore = transaction.objectStore("users");
var request = objectStore.openCursor();
request.onsuccess = function(evt) {
var cursor = evt.target.result;
if (cursor) {
output.textContent += "User: " + cursor.value.name + " email: " + cursor.value.email + " id: " + cursor.key + ".\n";
cursor.continue();
}else {
console.log("Records");
}
};
}, false);
btnClear.addEventListener("click", function () {
var transaction = db.transaction(["users"], "readwrite");
var objectStore = transaction.objectStore("users");
var request = objectStore.clear();
request.onsuccess = function (evt) {
console.log("All Records deleted!");
};
}, false);
}
window.addEventListener("DOMContentLoaded", contentLoaded, false);
})();//function()

I forgot. I get the error every time there is a
var transaction = db.transaction(["users"], "readwrite"); call.

From
NotFoundError = One of the names provided in the storeNames argument doesn't exist in this database.
Chrome didn't fire the upgradeneeded event until chrome 23 so the "users" objectstore isn't created.

Good, this is why it works in chromium and not in chrome.
How can i solve it? Moving the code
var objectStore = evt.currentTarget.result.createObjectStore("users", { keyPath: "id", autoIncrement: true });
objectStore.createIndex("name", "name", { unique: false });
objectStore.createIndex("email", "email", { unique: true });
from onupgradeneeded to onsuccess?

No - creating object stores and indexes can only be done in a "versionchange" transaction. When the "upgradeneeded" event is fired, a "versionchange" transaction has automatically been created for you.
With Chrome prior to 23 you need to create such a transaction manually by calling setVersion() - an API that has been removed from the spec. The older spec can be found at: http://www.w3.org/TR/2011/WD-IndexedDB-20110419/
IMHO, the easiest thing to do is to use a shim/polyfill to support the open(name, version) / "upgradeneeded" event versioning approach in older versions of Chrome, and drop the shim once 23 has gone stable. I posted such a shim at: https://gist.github.com/3361666 - but it is not rigorously tested.

Before version 23 we only used the obsolete setVersion mechanism. There's an informative blog post[1] that links to a shim you can use for older chrome versions[2]. There's a different shim you could use[3] that doesn't require you to call openReqShim instead of indexedDB.open. I haven't used either one so I can't vouch for them but others have had success.
