IDBTransaction class
The interface of the IndexedDB API provides a static,
asynchronous transaction on a database using event handler
attributes. All reading and writing of data is done within
transactions. You use IDBDatabase to start transactions, to set
the mode of the transaction (e.g. is it readonly or
readwrite), and you access an IDBObjectStore to make a
request. You can also use an object to abort transactions.
Note: This feature is available in Web Workers
EventTarget
IDBTransaction
Transactions are started when the transaction is created, not
when the first request is placed; for example consider this:
var trans1 = db.transaction("foo", "readwrite");
var trans2 = db.transaction("foo", "readwrite");
var objectStore2 = trans2.objectStore("foo")
var objectStore1 = trans1.objectStore("foo")
objectStore2.put("2", "key");
objectStore1.put("1", "key");
After the code is executed the object store should contain the
value "2", since trans2 should run after trans1.
