我可以提前结束 Promise.each 吗?

Can I end a Promise.each early?

db.Question.findAll({
  where: {
    PassageId: dbPassage.id,
    active: true,
    level: {
      $lte: startLevel,
      $gte: endLevel
    }
  },
  order: [db.Sequelize.fn('RANDOM')]
}).each(function(dbQuestion) {
  // End early if some condition
});

我正在使用 bluebird,我想知道是否可以提前退出 .each

我会做那样的事情。 (未测试)

var searchPromise = Promise.resolve();

searchPromise = db.Question.findAll({
  where: {
    PassageId: dbPassage.id,
    active: true,
    level: {
      $lte: startLevel,
      $gte: endLevel
    }
  },
  order: [db.Sequelize.fn('RANDOM')]
}).each(function(dbQuestion) {
  if (condition === true) {
    searchPromise.cancel();
  }
}).cancellable();
