从JSON中提取信息: P5.js

{
  "name": "John Doe",
  "age": 30,
  "isStudent": false,
  "courses": ["Math", "Science"]
}

// 假设jsonString是包含上述JSON的字符串
let jsonString = '{"name": "John Doe", "age": 30, "isStudent": false, "courses": ["Math", "Science"]}';

// 解析JSON字符串
let jsonObject = JSON.parse(jsonString);

// 提取信息
let name = jsonObject.name;
let age = jsonObject.age;
let isStudent = jsonObject.isStudent;
let courses = jsonObject.courses;

console.log(name); // 输出: John Doe
console.log(age); // 输出: 30
console.log(isStudent); // 输出: false
console.log(courses); // 输出: ["Math", "Science"]

let jsonString = '{"name": "John Doe", "age": 30, "isStudent": false, "courses": ["Math", "Science"]}';

try {
  let jsonObject = JSON.parse(jsonString);
  console.log(jsonObject);
} catch (error) {
  console.error("JSON解析错误:", error);
