如何检查值是否在JSON返回中？

function checkValueInJSON(jsonObj, valueToFind) {
    for (let key in jsonObj) {
        if (jsonObj.hasOwnProperty(key)) {
            if (jsonObj[key] === valueToFind) {
                return true;
            }
            if (typeof jsonObj[key] === 'object') {
                if (checkValueInJSON(jsonObj[key], valueToFind)) {
                    return true;
                }
            }
        }
    }
    return false;
}

// 示例JSON数据
const jsonData = {
    "name": "John",
    "age": 30,
    "city": "New York",
    "skills": ["JavaScript", "Python", "Java"]
};

// 检查值是否存在
const valueToFind = "Python";
const result = checkValueInJSON(jsonData, valueToFind);
console.log(`Value "${valueToFind}" found in JSON: ${result}`); // 输出: Value "Python" found in JSON: true
