按名称获取元素字符串

Question

我是JS的新人，所以我需要你的帮助。

我有这个JSON代码：

{
    "data": {
        "people": [

            "get_my_obj": [
                {
                    "yearcome": 2006,
                    "email": "email1@test.com",
                    "came": "1.12",
                    "name": "Alex "
                },
                {
                    "yearcome": 2010,
                    "email": "email2@test.com",
                    "came": "1.12",
                    "name": "John"
                },
                {
                    "yearcome": 2012,
                    "email": "email3@test.com",
                    "came": "1.12",
                    "name": "Max"
                }

            ]
                }
}

我如何通过电子邮件获取元素串？ 例如var a = email1@test.com; email2@test.com; email3@test.com;

这对我来说真的很难，因为如果我只有2个对象，那么如果3个对象显示3封电子邮件，则字符串必须显示2封电子邮件。

请帮我找到如何做的方法

Answer 1

var s = { data: ....};
var mails = s.data.people.get_my_obj.map(function (e) { return e.email; }).join(';');
console.log(mails);
