更改JSON结构响应

Question

I created the json response for the item using this code:

this.parts = this.getParts().filter((item) => {
  return item.manufactureId === Number(manufactureId)
  });

it's return the ID of part from my this json:

[{id: 02020013, manufactureId: 0202, name: cable}]

I also tried using this code but not working :(":

this.parts = this.getParts.filter(p => (p.id == manufactureId))[0].name;

What I want to achieved is, the response will parse the item name instead of part.id.

As pointed in comments you can change you last code bit to

this.parts = this.getParts().filter(p => (p.manufactureId == manufactureId))[0].name;

You were missing parenthesis to call a function. And you might need to filter by manufactureId , not id .

As well you can use map function after filtering data by manufactureId . map function applies function for each array element and return result, in this example it simple get name from object, because there might be more that one (or none) item by manufactureId .

this.parts = this.getParts().filter((item) => {
    return item.manufactureId === Number(manufactureId)
}).map((item) => item.name);
