IDBDatabase.deleteObjectStore()

The deleteObjectStore() method of the IDBDatabase interface destroys the object store with the given name in the connected database, along with any indexes that reference it.

As with IDBDatabase.createObjectStore, this method can be called only within a versionchange transaction.

Note: This feature is available in Web Workers

Syntax

Parameters

The name of the object store you want to delete. Names are case sensitive.

Exceptions

TransactionInactiveError DOMException

Thrown if a request is made on a source database that doesn't exist (E.g. has been deleted or removed.)

NotFoundError DOMException

Example

var dbName = "sampleDB";
var dbVersion = 2;
var request = indexedDB.open(dbName, dbVersion);

  var db = request.result;
  if (e.oldVersion < 1) {
    db.createObjectStore("store1");
  }
