GlobalEventHandlers.onabort
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The onabort property of the
GlobalEventHandlers mixin is the event handler for
processing abort events sent to the window.
While the standard
for aborting a document load is defined, HTML issue #3525 suggests that
browsers should not currently fire the abort event on a Window
that would trigger onabort to be called.
TODO: define what "abort" is. Closing the window via window manager? Stopping the load
of the page? By which means and reasons (user, network/server)? At which stages would it
fire / be caught? For IE, onabort is only available with
<img> tags.
Syntax
window.onabort = functionRef;
Value
functionRef is a function name or a function
expression.
Example
window.onabort = function() {
alert('Load aborted.');
}
