从forEach推送对象后，数组保持为空 [英] Array keep empty after push object from forEach

问题描述

需要帮助，我遇到问题数组保持为空从forEach推入对象后，我会错过任何东西吗?这是代码:

Need Help, I have problem Array Keep Empty After pushing object from forEach, do I miss something ? here's the code :

const allStatus = [];
    result.forEach(async (element) => {
      const count = await BpCandidate.count({
        where: {
          applicationStatusId: element.id
        },
        raw: true,
      });
      })  
      record = {
        id: element.id,
        name: element.name,
        code: element.code,
        description: element.description,
        total: count
      };
      allStatus.push(record);
    });
    console.log(allStatus);

预先感谢

推荐答案

使用 for ... of 可以为您工作，但是如果您使用 Promise.all，可以在这里看到改进.

Using for...of is working for you, but can see an improvement here if you use Promise.all

const allStatus = await Promise.all(result.map(async (element) => {
  const count = await BpCandidate.count({
    where: {
      applicationStatusId: element.id
    },
    raw: true,
  });
  return  {
    id: element.id,
    name: element.name,
    code: element.code,
    description: element.description,
    total: count
  };
}))
