$timeout

  1. - service in module ng

Angular's wrapper for window.setTimeout. The fn function is wrapped into a try/catch block and delegates any exceptions to $exceptionHandler service.

The return value of calling $timeout is a promise, which will be resolved when the delay has passed and the timeout function, if provided, is executed.

To cancel a timeout request, call $timeout.cancel(promise).

In tests you can use $timeout.flush() to synchronously flush the queue of deferred functions.

If you only want a promise that will be resolved after some specified delay then you can call $timeout without the fn function.

Usage

$timeout([fn], [delay], [invokeApply], [Pass]);
