Angular.js范围原始值 - 缩短功能？

Question

我的范围内有原始值，我想知道是否有更好的方法来处理这些值并缩短我看起来臃肿的功能。

angular.module('main.loadbalancer').controller('CreateNodeCtrl', function($scope, $modalInstance, LoadBalancerService, StatusTrackerService, NodeService) {
  $scope.createNode = function(node) {
    var TIME_CLOSE_MODAL;
    TIME_CLOSE_MODAL = 3000;
    $scope.disableButtonsForRun = false;
    $scope.statusBar = true;
    $scope.nodeStatus = 'Building';
    $scope.statusType = 'warning';
    return LoadBalancerService.getLoadBalancer().then(function(loadBalancer) {
      return NodeService.createNode({
        account_number: loadBalancer.customer,
        admin_state: 'enabled',
        label: node.label,
        ip: node.ip,
        port: node.port,
        comment: node.comment,
        health_strategy: {},
        vendor_extensions: {}
      }).then(function(eventId) {
        trackStatus = void 0;
        $scope.disableButtonsForRun = true;
        StatusTrackerService.runEventCheck(loadBalancer.customer, eventId)
        .then(function() {
          $scope.statusType = 'success';
          $scope.nodeStatus = 'Completed Successfully';
          setTimeout((function() {
            $modalInstance.close();
          }), TIME_CLOSE_MODAL);
        }, function() {
          $scope.nodeStatus = 'Failure!';
          $scope.statusType = 'danger';
        })['finally'](function() {
          $scope.disableButtonsForRun = false;
        });
      });
    });
  };
  $scope.node = {
    keepaliveType: 'TCP',
    keepaliveMethod: 'GET'
  };
  $scope.close = function() {
    $scope.nodeStatus = 'Building';
    $scope.statusType = 'warning';
    $modalInstance.close();
  };});
