The objectStoreNames read-only property of the IDBDatabase interface is a DOMStringList containing a list of the names of the object stores currently in the connected database.
Note: This feature is available in Web Workers.
Syntax
var list[] = IDBDatabase.objectStoreNames;
Value
A DOMStringList containing a list of the names of the object stores currently in 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
// an object that looks like { ['my-store-name'] }
console.log(db.objectStoreNames);
};
