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()
.
