Typescript 基于另一个数组对嵌套数组进行数据过滤

Question

我是 TS 的新手，我有一组看起来像这样的数据

const AllJobs = [
      {
        title: Teller,
        salary: ["Hourly"],
        industries: [
          "Accounting",
          "Banking",
          "Data"
        ]
      },
      {
        title: Scientist,
        salary: ["Yearly"],
        industries: [
          "Biology",
          "Chemicals",
          "Science"
        ]
      },
        {
        title: Artist,
        salary: ["Hourly"],
        industries: [
          "Design",
          "Paint",
          "Color"
        ]
      },
    ];

let desiredSkills = ["Design","Accounting","Data"];

我想遍历 AllJobs 数组中“行业”中的数据，并检查这些值中的任何一个是否与所需技能中的任何值匹配。 如果没有匹配值，则过滤掉该 object。 我不知道我这样做是否正确。

期望的结果：

 const AllJobs = [
          {
            title: Teller,
            salary: ["Hourly"],
            industries: [
              "Accounting",
              "Banking",
              "Data"
            ]
          },
            {
            title: Artist,
            salary: ["Hourly"],
            industries: [
              "Design",
              "Paint",
              "Color"
            ]
          },
        ];

这是我以前的代码。 这目前不起作用。

const getSuggested = (item: string) => {
   const filterIndustry = this.allJobs.filter((x:any) => x['industries'].every((y: string | any[])=> y.includes(item)));
  };
this.desiredIndustries.forEach(getSuggested);

我也试过

 const getSuggested = (item: string) => {
 let k = item;

 const data = this.allJobs.filter((item: { industries: any }) => item.industries == k);
 console.log(data);
 };
 this.desiredIndustries.forEach(getSuggested);

您在这里并不需要 TypeScript，所以这里有一个适合您的 JS 解决方案：

 const AllJobs = [{ title: 'Teller', salary: ['Hourly'], industries: ['Accounting', 'Banking', 'Data'], }, { title: 'Scientist', salary: ['Yearly'], industries: ['Biology', 'Chemicals', 'Science'], }, { title: 'Artist', salary: ['Hourly'], industries: ['Design', 'Paint', 'Color'], }, ]; let desiredSkills = ['Design', 'Accounting', 'Data']; const result = AllJobs.filter(({ industries }) => industries.find((industry) => desiredSkills.includes(industry))); console.log(result);

应该很容易翻译成TS。 希望能帮助到你！
