Draft: This page is not complete.

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.');
}
