我使用的是 Angular 4，我调用了一个返回对象数组的 api。
然后我尝试通过引用 res.name 来获取特定数据，但由于某种原因我未定义，所以我尝试了 res[0]name 和 res[ 'name'] 只返回名字，但我想要数组中的所有名称。
这是我的数组:
[{"name":"joey","surname":"jackson","email":"joey@gmail.com","phone":"0815342119"},
{"name":"Tim","surname":"Muller","email":"tim@gmail.com","phone":""},
{"name":"Kim","surname":"Van Dam","email":"kim@gmail.com","phone":""},
{"name":"Lyn","surname":"Davids","email":"lyn@gmail.com","phone":""}]
最佳答案
尝试使用 forEach 迭代数组的所有元素:
let res = [
{"name":"joey","surname":"jackson","email":"joey@gmail.com","phone":"0815342119"},{"name":"Tim","surname":"Muller","email":"tim@gmail.com","phone":""},{"name":"Kim","surname":"Van Dam","email":"kim@gmail.com","phone":""},{"name":"Lyn","surname":"Davids","email":"lyn@gmail.com","phone":"08343435"}
];
res.forEach( (el) => {
console.log(el.name);
