web.storage.IDBTransaction — clojure-interop/cljs-web-api 1.0.10

Note that as of Firefox 40, IndexedDB transactions have relaxed guarantees to increase performance (see bug 1112702.) Previously a readwrite transaction IDBTransaction.oncomplete was fired when all data was guaranteed to have been flushed to disk. In 40+ the complete event is fired after the OS has been told to the data but potentially before that data has actually been flushed disk. The complete event may thus be delivered quicker than before, there exists a small chance that the entire transaction will lost if the OS crashes or there is a loss of system power before data is flushed to disk. Since such catastrophic events are rare consumers should not need to concern themselves further.

[Read Only]

A web.deprecated.DOMError containing the relevant error. In 48+/Firefox 58+ this property returns a web.DOMException because has been removed from the DOM standard.

onabort cljs

(onabort this)

Property.

In the following code snippet, we open a read/write transaction our database and add some data to an object store. Note also functions attached to transaction event handlers to report on outcome of the transaction opening in the event of success or Note the transaction.onabort = function(event) { }; block, reporting the transaction has been aborted. For a full working example, our To-do Notifications app (view example live.)

transaction.onabort = function(event) { ... };
