It’s a nice day for coding,isn’t it?Ha ha!
今天遇到一种服务端响应的参数，key是动态的
就像这样
我们一般静态key取值就是直接
data.data.id.username
但这种id是动态的
我们就只能用for in的方式取值了
var data = { "msg": "查询成功！", "code": 200, "data": { "2f793b1baf4b441c99a12d22af6678aa": { "username": "ruben2", "password": null, "userInfo": null, "genderEnum": null }, "59fa61fe88b64df58568a7046f17ab38": { "username": "ruben0", "password": null, "userInfo": null, "genderEnum": null }, "6996ac2dfefa42548111224e344052d6": { "username": "ruben1", "password": null, "userInfo": null, "genderEnum": null } }, "success": true }; console.log(data); for (const user in data.data) { if (data.data.hasOwnProperty(user)) { const element = data.data[user]; console.log(element.username); } }
输出结果
