我有一个API数组，我正在练习使用。下面是数组中的一个对象，名为users。我知道要访问属性，比如firstName，我只需写 {users.firstName}
address属性。我以为应该是 {users.address.address}
{
"id": 1,
"firstName": "Terry",
"lastName": "Medhurst",
"maidenName": "Smitham",
"age": 50,
"gender": "male",
"email": "atuny0@sohu.com",
"phone": "+63 791 675 8914",

您很可能没有对数组进行循环。要获取用户的地址，您需要获取
users数组中的每个对象，然后可以在每个对象上运行.address.address。请参考下面的代码片段：const users = [{ "id": 1, "firstName": "Terry", "lastName": "Medhurst", "maidenName": "Smitham", "age": 50, "gender": "male", "email": "atuny0@sohu.com", "phone": "+63 791 675 8914", "username": "atuny0", "password": "9uQFF1Lh", "birthDate": "2000-12-25", "image": "https://robohash.org/hicveldicta.png", "bloodGroup": "A−", "height": 189, "weight": 75.4, "eyeColor": "Green", "hair": { "color": "Black", "type": "Strands" }, "domain": "slashdot.org", "ip": "117.29.86.254", "address": { "address": "1745 T Street Southeast", "city": "Washington", "coordinates": { "lat": 38.867033, "lng": -76.979235 }, "postalCode": "20020", "state": "DC" }, "macAddress": "13:69:BA:56:A3:74", "university": "Capitol University", "bank": { "cardExpire": "06/22", "cardNumber": "50380955204220685", "cardType": "maestro", "currency": "Peso", "iban": "NO17 0695 2754 967" }, "company": { "address": { "address": "629 Debbie Drive", "city": "Nashville", "coordinates": { "lat": 36.208114, "lng": -86.58621199999999 }, "postalCode": "37076", "state": "TN" }, "department": "Marketing", "name": "Blanda-O'Keefe", "title": "Help Desk Operator" }, "ein": "20-9487066", "ssn": "661-64-2976", "userAgent": "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/12.0.702.0 Safari/534.24" }]; function App() { return users.map(el => <h1>{el.address.address}</h1>); } // Render it ReactDOM.render(<App /> , document.getElementById("root"));
