如何遍历Record< K，T> [英] How to loop though Record<K, T>

问题描述

我具有记录的 Records 类型:

export interface List {
  name: string;
  title: string;
}

export type RecordType
= 'recordOne'
| 'recordTwo'
| 'recordThree';

export const Records: Record<RecordType, List> = {
  recordOne: {
    name: 'Name1',
    title: 'Ausi bere ut erit adeo enim an suae'
  },
  recordTwo: {
    name: 'Name2',
    title: 'Petebat proprie suo methodo'
  },
  recordThree: {
    name: 'Name3',
    title: 'Petebat proprie suo methodo inscitiae'
  }
}

我想搜索带有特定文本的记录，但是要做到这一点，我需要遍历 Records ，那么您将如何做呢?我的意思是您会如何循环想到 Records ?

I want to search for record with specific text but in order to do that I need to loop through the Records so how would you do that? I mean how would you loop thought the Records ?

基本上就是我想要的:

findMatchingTitle(myString) {
   let title = '';
   this.Records.foreach(x => {

     if(myString.includes(x.title)) {
       title = x.title;
     }
   });

  return title;
}

有什么想法吗?

推荐答案

与TS并不真正相关，为了搜索标题，我首先将记录值作为数组，然后使用Array.find查找标题.

Not really related to TS, in order to search for the title, I would first get the records values as array, and use the Array.find to look for the title.

如果找到一个，我将获得它的标题

if I found one, I will get its title

const records = {
  recordOne: {
    name: 'Name1',
    title: 'Ausi bere ut erit adeo enim an suae'
  },
  recordTwo: {
    name: 'Name2',
    title: 'Petebat proprie suo methodo'
  },
  recordThree: {
    name: 'Name3',
    title: 'Petebat proprie suo methodo inscitiae'
  }
}

const findMatchingTitle = str => Object.values(records).find(record => record.title.includes(str))?.title

console.log(findMatchingTitle("inscitiae"))
