CloseWatcher: close() method

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The close() method of the CloseWatcher interface lets you skip any logic in the cancel event handler and immediately fire the close event. It then deactivates the close watcher as if destroy() was called.

Syntax

js
close()

Parameters

None.

Return value

None (undefined).

Examples

Using the close() method

Use the close() method to deactivate the close watcher and destroy it.

js
watcher.close();
