why do I have a error ?
My code:
var idb = window.indexedDB || // Use the standard DB API
window.mozIndexedDB || // Or Firefox's early version of it
window.webkitIndexedDB; // Or Chrome's early version
var IDBTransaction = window.IDBTransaction || window.webkitIDBTransaction;
var IDBKeyRange = window.IDBKeyRange || window.webkitIDBKeyRange;
var dbName='nameDb';
var idbRequest=idb.open(dbName,'4.67' /*,dbDescription */);
idbRequest.onsuccess=function (e) {
debugger
var db=e.target.result;
if (!db.objectStoreNames.contains('chat')){
co=db.createObjectStore('chat',{'id':100});
};
if (!db.objectStoreNames.contains('iam')){
co1=db.createObjectStore('iam');
};
};
idbRequest.onerror = function (e) {
debugger
};
Uncaught InvalidStateError: Failed to execute 'createObjectStore' on 'IDBDatabase': The database is not running a version change transaction. index.html:37 idbRequest.onsuccess
You can't create an objectStore
in an onsuccess
method. You can only do this in a upgradeneeded
event.
Quote from docs:
When you create a new database or increase the version number of an existing database (by specifying a higher version number than you did previously, when Opening a database), the
onupgradeneeded
event will be triggered. In the handler for this event, you should create the object stores needed for this version of the database
