The getAll()
method of the IDBObjectStore
interface returns an IDBRequest
object containing all objects in the object store matching the specified parameter or all objects in the store if no parameters are given.
If a value is successfully found, then a structured clone of it is created and set as the result
of the request object.
Note: This method produces the same result for: a) a record that doesn't exist in the database and b) a record that has an undefined value. To tell these situations apart, call the
openCursor()
method with the same key. That method provides a cursor if the record exists, and no cursor if it does not.Syntax
var request = objectStore.getAll([query, count]);
Returns
An IDBRequest
object on which subsequent events related to this operation are fired.
Parameters
- query Optional
- A key or
IDBKeyRange
to be queried. If nothing is passed, this will default to a key range that selects all the records in this object store. - count Optional
- Specifies the number of values to return if more than one is found.
