如何訪問 json 對(duì)象

如何訪問 json 對(duì)象

慕娘9325324 2022-07-08 18:20:22
我正在嘗試創(chuàng)建網(wǎng)頁，它使用來自 Breaking bad website 的 APi，并且從這個(gè)網(wǎng)站我收到了 JSON 格式的數(shù)據(jù)，我嘗試了很多，但不明白，我如何才能只訪問“作者”的對(duì)象" 是 "Walter White" 這是接收到的數(shù)據(jù)。[{"quote_id":1,"quote":"我沒有危險(xiǎn)，Skyler。我就是危險(xiǎn)！","author":"Walter White","series":"Breaking Bad"},{"quote_id ":2,"quote":"遠(yuǎn)離我的領(lǐng)域。","author":"Walter White","series":"Breaking Bad"},{"quote_id":3,"quote":"IFT" ,"author":"Skyler White","series":"Breaking Bad"},{"quote_id":4,"quote":"我看著簡(jiǎn)死去。我在那兒。我看著她死去。我看著她過量并窒息而死。我本可以救她。但我沒有。","author":"Walter White","series":"Breaking Bad"},{"quote_id":5,"quote": “說我的名字?！?，”author":"Walter White","series":"Breaking Bad"}]

您可以在此處使用數(shù)組.filter()方法，例如：


var data = [{quote_id:1,quote:"I am not in danger, Skyler. I am the danger!",author:"Walter White",series:"Breaking Bad"},{quote_id:2,quote:"Stay out of my territory.",author:"Walter White",series:"Breaking Bad"},{quote_id:3,quote:"IFT",author:"Skyler White",series:"Breaking Bad"},{quote_id:4,quote:"I watched Jane die. I was there. And I watched her die. I watched her overdose and choke to death. I could have saved her. But I didn’t.",author:"Walter White",series:"Breaking Bad"},{quote_id:5,quote:"Say my name.",author:"Walter White",series:"Breaking Bad"}];


var res = data.filter(d => d.author === 'Walter White')

console.log( res )

.as-console-wrapper { max-height: 100% !important; top: 0; }

您可以使用filter. 注意toLowerCase()用于不區(qū)分大小寫的結(jié)果。


const filterKey = 'walter white';

let data = [{

  "quote_id": 1,

  "quote": "I am not in danger, Skyler. I am the danger!",

  "author": "Walter White",

  "series": "Breaking Bad"

}, {

  "quote_id": 2,

  "quote": "Stay out of my territory.",

  "author": "Walter White",

  "series": "Breaking Bad"

}, {

  "quote_id": 3,

  "quote": "IFT",

  "author": "Skyler White",

  "series": "Breaking Bad"

}, {

  "quote_id": 4,

  "quote": "I watched Jane die. I was there. And I watched her die. I watched her overdose and choke to death. I could have saved her. But I didn’t.",

  "author": "Walter White",

  "series": "Breaking Bad"

}, {

  "quote_id": 5,

  "quote": "Say my name.",

  "author": "Walter White",

  "series": "Breaking Bad"

}].filter(item => item.author.trim().toLowerCase() === filterKey);


console.log(data)
