如何将类型分配给字符串输入作为要推送的对象

Question

我有一个 forEach 接受一个字符串并推送一个对象。我该如何正确输入？

const descriptionText: string = this.args.post.description || '';
const descriptionParts: string[] = descriptionText.split(/\s+/g);
let parsedDescriptionParts: object[] = [];

descriptionParts.forEach((text: string) => {
    let parts = {
       text,
       isLink: false
    }
    if (text.match('^(#|@)')) {
       parts = {
          text: `<span class=${this.boldClass}>${text}</span>`,
          isLink: true
       };
    }
    parsedDescriptionParts.pushObject(parts);
});

return parsedDescriptionParts;

Answer 1

在我看来，forEach 从来没有输出。

这是lib.es5.d.ts

中forEach的定义

forEach(callbackfn: (value: T, index: number, array: T[]) => void, thisArg?: any): void;

所以也许您的类型是：(string) => void

Answer 2

let descriptionParts: string[] = ['hello', '#goodbye']                                                                                     
let boldClass: string = 'abc'

let parsedDescriptionParts: object[] = descriptionParts
  .map(text => text.match('^(#|@)')
    ? { text: `<span class=${boldClass}>${text}</span>`, isLink: true }
    : { text, isLink: false }
  )

console.log(parsedDescriptionParts)
