JavaScript。从关联数组中提取值

Question

如何在 JavaScript 中从这个关联数组中获取值？

我只需要电子邮件地址而不是标签。

(
  {
    office = ("my@email.com");
    home = ("ahome@anotheremail.com");
    work = ("nothing@email.com");
  },
  {
    home = ("test@test.se");
  }
)

更新:JSON 格式的首选输出是:

{
    "data": [
        {
            "email": "my@email.com"
        },
        {
            "email": "ahome@anotheremail.com"
        },
        {
            "email": "nothing@email.com"
        },
        {
            "email": "test@test.se"
        }
    ]
}

感谢所有输入!

你可能打算做的是:

var x = [{
 office: ("my@email.com"),
 home: ("ahome@anotheremail.com"),
 work: ("nothing@email.com")
},
{
 home: ("test@test.se")
}]

和:

for(var j = 0; j < x.length; j++)
{
    for(var anItem in x[j])
    {
        console.log(x[j][anItem])
    }
}

//编辑:但是，it's not the best practice用于……在。

也许您可以将数据结构更改为:

var x = [[{
        value: "my@email.com",
        type: "office"
    },
    {
        value: "ahome@anotheremail.com",
        type: "home"
    },
    {
        value: "nothing@email.com",
        type: "work"
    }],
    [{
        value: "test@test.se",
        type: "home"
    }]];

并迭代使用:

for( var i = 0, xlength = x.length; i < xlength; i++ )
{
    for( var j=0, ylength = x[i].length; j < ylength; j++ )
    {
        console.log(x[i][j].value);
    }
}
