The getAll() method of the IDBIndex interface retrieves all objects that are inside the index.
There is a performance cost associated with looking at the value property of a cursor, because the object is created lazily. To use a feature like getAll(), the browser has to create all the objects at once. If you are just interested in looking at each of the keys, for instance, it is more efficient to use a cursor. If you are trying to get an array of all the objects in an object store, though, you should use getAll().
getAll()
getAll(query)
getAll(query, count)
An IDBRequest object on which subsequent events related to this operation are fired.
If the operation is successful, the value of the request's result property is an Array of the values of all records matching the given query, up to the value of count, if count was supplied.
This method may raise a DOMException of the following types:
-
TransactionInactiveError DOMException
-
Thrown if this IDBIndex's transaction is inactive.
-
InvalidStateError DOMException
-
Thrown if the IDBIndex has been deleted or removed.
A TypeError exception is thrown if the count parameter is not between 0 and 2^32 - 1 included.
const myIndex = objectStore.index("index");
const getAllRequest = myIndex.getAll();
getAllRequest.onsuccess = () => {
console.log(getAllRequest.result);
};
