无法使用JQ在JSON中获取项目

// 假设我们有以下JSON数据
var jsonData = {
  "name": "John",
  "age": 30,
  "city": "New York",
  "nestedObject": {
    "property1": "value1",
    "property2": "value2"
  },
  "arrayProperty": ["item1", "item2", "item3"]
};

// 获取JSON中的项目
var name = jsonData.name;
var age = jsonData.age;
var city = jsonData.city;
var nestedObject = jsonData.nestedObject;
var property1 = nestedObject.property1;
var property2 = nestedObject.property2;
var arrayProperty = jsonData.arrayProperty;

// 打印获取的结果
console.log("name:", name);
console.log("age:", age);
console.log("city:", city);
console.log("property1:", property1);
console.log("property2:", property2);
console.log("arrayProperty:", arrayProperty);
