我正在嘗試創建網頁，它使用來自 Breaking bad website 的 APi，并且從這個網站我收到了 JSON 格式的數據，我嘗試了很多，但不明白，我如何才能只訪問“作者”的對象" 是 "Walter White" 這是接收到的數據。[{"quote_id":1,"quote":"我沒有危險，Skyler。我就是危險！","author":"Walter White","series":"Breaking Bad"},{"quote_id ":2,"quote":"遠離我的領域。","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()用于不區分大小寫的結果。

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)
