javascript - TS 中 "every"函数的 TypeError

Question

我正在开发一个项目，该项目根据工作计划和用户的个人可用性过滤工作。

const jobs: JobRecord[] = [
  {
    "storeName": "Highwire Coffee Company",
    "schedule":  [
      "Tuesday",
      "Thursday",
    ],
        ...
  },
  {
    "storeName": "Blue Bottle Coffee",
    "rid": "recNgeUMcYhWUxw8b",
    "schedule":  [
      "Thursday",
    ],
    ...
  },
] 

const availability: Availability = {
  "friday": false,
  "monday": false,
  "thursday": true,
  "tuesday": false,
  "wednesday": true,
}

例如，鉴于上面的这些输入，我应该创建一个函数，只返回商店名称为“Blue Bottle Coffee”的作业。
为此，我编写了这两个函数。

  findAvailableDays (availability: Availability){
    var availDays: string[];
    availDays = [];
    for (const [day, avail] of Object.entries(availability)){
      if (avail){
        availDays.push(day);
      }
    }
    return availDays;
  };

  filterJobs = (jobs: JobRecord[], availability: Availability): void => {
    // Step 0: Clone the jobs input
    const newJobs: JobRecord[] = cloneDeep(jobs);
    console.log(newJobs, availability);

    // Step 1: Remove jobs where the schedule doesn't align with the users' availability.
    for (const[store, schedule] of Object.entries(jobs)){
      var availDays: string[];
      availDays = this.findAvailableDays(availability);
      const checkIncludes = (currentValue) => availDays.includes(currentValue);
      let checker = (availDays, schedule) => schedule.every(checkIncludes(checkIncludes));
      if(!checker(availDays, schedule)){
        delete newJobs[store];
      }
    }
    // Step 2: Save into state
    this.setState({ jobs: newJobs });
  };

但是，我在 filterJobs 中的 every() 函数总是遇到错误(如下所示)。我已经检查了 every() 是否接受函数作为参数(我确定)，并且适用于数组(我相信 schedule 应该是一个数组，给出的例子)。我在这里做错了什么/错过了什么？我应该尝试找到另一种方法来解决这个问题吗？

schedule不是数组，而是 JobRecord .您可能是这个意思，schedule从 JobRecord 解构:

for (const [store, {schedule}] of Object.entries(jobs)) {

但是，编写整个内容的更好方法是不按索引删除 - 使用 filter反而:

filterJobs = (jobs: JobRecord[], availability: Availability): void => {
  const availDays = this.findAvailableDays(availability);

  const filteredJobs = jobs.filter(({schedule}) =>
    schedule.every(day => availDays.includes(day)));

  this.setState({ jobs: filteredJobs });
};

看起来您可能需要考虑 availability 的属性名称之间的大小写差异。和 schedule 的元素， 顺便一提。
