The proposed getAllKeys() method of the IDBIndex interface would instantly retrieve the keys of all objects inside the index, setting them as the result of the request object.
Syntax
var allKeysRequest = IDBIndex.getAllKeys(); var allKeysRequest = IDBIndex.getAllKeys(query); var allKeysRequest = IDBIndex.getAllKeys(query, count);
Parameters
- query Optional
- A key or an
IDBKeyRangeidentifying the keys to retrieve. If this value is null or missing, the browser will use an unbound key range. - count Optional
- The number records to return. If this value exceeds the number of records in the query, the browser will only retrieve the first item. If it is lower than
0or greater than232-1aTypeErrorexception will be thrown.
Return value
An IDBRequest object on which subsequent events related to this operation are fired.

This method may raise a DOMException of the following types:
| Exception | Description |

A TypeError exception is thrown if the count parameter is not between 0 and 232-1 included.
