How to get a JSON value using Javascript into a variable-CodePudding

So I have this JSON:

{
    "success": {
        "total": 1
    },
    "contents": {
        "quotes": [
            {
                "quote": "When you win, say nothing. When you lose, say less.",
                "length": "51",
                "author": "Paul Brown",
                "tags": {
                    "0": "inspire",
                    "1": "losing",
                    "2": "running",
                    "4": "winning"
                },
                "category": "inspire",
                "language": "en",
                "date": "2022-03-05",
                "permalink": "https://theysaidso.com/quote/paul-brown-when-you-win-say-nothing-when-you-lose-say-less",
                "id": "3dlKxoNAOZsB__Nb61H95weF",
                "background": "https://theysaidso.com/img/qod/qod-inspire.jpg",
                "title": "Inspiring Quote of the day"
            }
        ]
    },
    "baseurl": "https://theysaidso.com",
    "copyright": {
        "year": 2024,
        "url": "https://theysaidso.com"
    }
}

I am trying to grab the text in the author and quote fields into two respective variables. I've already assigned the variable JSON to the json contents. What I have right now is the following below that doesn't work.

QUOTE = JSON.contents.quotes[0].quote;
AUTHOR = JSON.contents.quotes[0].author;

What am I doing wrong? And what would be the correct approach?

CodePudding user response：

did you require the json file? it works fine for me. also add let or var before the variable

var json = require('./2.json')

let QUOTE = json.contents.quotes[0].quote;
let AUTHOR = json.contents.quotes[0].author;

console.log(QUOTE, AUTHOR);

this output is When you win, say nothing. When you lose, say less. Paul Brown

I've already assigned the variable JSON to the json contents.

From your explanation, I assume that you did assign the contents object to the variable JSON. In that case, you needed to access the properties using JSON.quotes[0].quote and JSON.quotes[0].author. Please refer the snippet below.

var yourObject = {
  "success": {
    "total": 1
  },
  "contents": {
    "quotes": [{
      "quote": "When you win, say nothing. When you lose, say less.",
      "length": "51",
      "author": "Paul Brown",
      "tags": {
        "0": "inspire",
        "1": "losing",
        "2": "running",
        "4": "winning"
      },
      "category": "inspire",
      "language": "en",
      "date": "2022-03-05",
      "permalink": "https://theysaidso.com/quote/paul-brown-when-you-win-say-nothing-when-you-lose-say-less",
      "id": "3dlKxoNAOZsB__Nb61H95weF",
      "background": "https://theysaidso.com/img/qod/qod-inspire.jpg",
      "title": "Inspiring Quote of the day"
    }]
  },
  "baseurl": "https://theysaidso.com",
  "copyright": {
    "year": 2024,
    "url": "https://theysaidso.com"
  }
}

let JSON = yourObject.contents

let yourQuote = JSON.quotes[0].quote
let yourAuthor = JSON.quotes[0].author

console.log(yourQuote)
console.log(yourAuthor)
