IDBFactory.deleteDatabase()

The deleteDatabase() method of the IDBFactory interface requests the deletion of a database. The method returns an IDBOpenDBRequest object immediately, and performs the deletion operation asynchronously.

If the database is successfully deleted, then a success event is fired on the request object returned from this method, with its result set to undefined. If an error occurs while the database is being deleted, then an error event is fired on the request object that is returned from this method.

Will trigger an upgradedneeded event and, if any other tabs have open connections to the database, a blocked event.

Note: This feature is available in Web Workers.

Syntax

For the current standard:

var request = window.indexedDB.deleteDatabase("toDoList");

For the experimental version with options (see below):

var request = window.indexedDB.deleteDatabase("toDoList", { storage: "temporary" });

Parameters

name
The name of the database.
options Non-standard
In Gecko, since version 26, you can include a non-standard optional storage parameter that specifies whether you want to delete a permanent (the default value) IndexedDB, or an indexedDB in temporary storage (aka shared pool.)

Return value

A IDBOpenDBRequest on which subsequent events related to this request are fired.

Example

var DBDeleteRequest = window.indexedDB.deleteDatabase("toDoList");

DBDeleteRequest.onerror = function(event) {
  console.log("Error deleting database.");
};
 
DBDeleteRequest.onsuccess = function(event) {
  console.log("Database deleted successfully");
    
  console.log(request.result); // should be null
};

Be careful in Chrome as it still implements the old specification along with the new one. Similarly it still has the prefixed webkitIndexedDB property even if the unprefixed indexedDB is present.
