从Typescript角度的json对象中获取数组

Question

我有一个json对象，它由字符串元素以及一个array类型的元素组成。我不知道如何获取object的json对象。以下是我的代码段。

getData(){
    this.productService.getliveData().subscribe(resp => {
      this.catDta = resp['categories'];
      const products: any = [];
      const jsonobject = resp['categories'];
      this.newestItems=jsonobject['cat_products'];
      console.log('newwest items2',jsonobject['cat_products']);

    });
  }

我只想知道如何从类别对象中获取类型为数组的cat_products。

任何帮助将不胜感激。

下面是json

{
            "id": "3",
            "title": "Suspension",
            "parent_id": "1",

我需要访问cat_products。请帮助我

Answer 1

如果resp是json结构中的对象，那么您可以通过以下方式访问其产品：

const products = resp['cat_products'];
