使用$timeout停止执行一系列事件

Question

我正在使用此解决方案来启动序列。但现在我想停止点击。点击事件如果发射OK，我已经在console.log上确认。我已经尝试了

$timeout.cancel($scope.StartChange);

但没有成功，阶级仍在改变。

这很有效，但我不知道这是否是最好的解决方案：http://plnkr.co/edit/xKBHdFhXy93NqtpVooXe?p=preview

  var savePromise = function(promiseObj) {
    //saves promise and returns it
    $scope.terminateEarly.push(promiseObj);
    return promiseObj;
  };
  $scope.startChange = function() {
    console.log('start');
    $scope.state = 'b';
    console.log($scope.state);
    return savePromise($timeout(angular.noop, 3 * 1000))
     .then(function() {
      $scope.state = 'c';
      console.log($scope.state);
      return savePromise($timeout(angular.noop, 6 * 1000))})
      .then(function() {
        $scope.state = 'd';
        console.log($scope.state);
        return savePromise($timeout(angular.noop, 12 * 1000))})
        .then(function() {
          $scope.state = 'e';
           console.log($scope.state);
    });
  };
  $scope.stopChange = function(tId) {
    console.log('stop');
    $scope.terminateEarly.forEach(function(t){
      $timeout.cancel(t);
    });
  };
