AngularJS. Clear $timeout when invoking angular-ui modal

The $timeout service returns a Promise object which can be used to cancel the timeout.

// Start a timeout
var promise = $timeout(function() {}, 1000);

// Stop the pending timeout
$timeout.cancel(promise);

To cancel all pending timeouts, you need to maintain a list of promises and cancel the complete list when you open the modal.

You may also let them cancel themselves by doing this...

(function(){
  var timer = $timeout(function(){
    console.log(timer.$$timeoutId);
    $timeout.cancel(timer);
  }, 1000);
})();
