close
events are generated by several APIs:
- HTML DOM
- Sent to a target
<dialog>
to let it know that it has been closed. - IndexedDB API
- Sent to the
IDBDatabase
object representing a database connection when the database is unexpectedly closed. This happens after all transactions have been aborted. You can useIDBDatabase.onclose
to establish the event handler. - WebRTC API
- Sent to an
RTCDataChannel
to let it know that a data connection has been terminated. You can use theRTCDataConnection.onclose
property to establish an event handler for this, in addition to usingaddEventListener()
. - WebSocket API
- Sent when a WebSocket connection closes. More information needed here.
- Web Workers API
- Some browsers used a close event to indicate that a given
Worker
had shut down; this was at one point part of the specification, but has been removed from the spec, and browsers are in the process of removing support for this event in the Web Workers API.
