循环数组值

  • 772
let mass = {
    "a": {
        c1: "aaaa",
        c2: "bbbb",
        c7: "ffff"
    },

    "b": {
        c1: "ccc",
        c2: "dddd",
        c10: "tttt"
    },

    "c": {
        c1: "ffff",
        c2: "kkkk",
        c3: "mmmm"
    }
}

告诉我，如何在控制台中显示所有电子邮件 c1 和 c2？我可以显示一些特定的电子邮件，例如通过编写 console.log(mass.a.c1)。我怎么能在一个循环中做到这一点？

javascript

    let mass = {
    "a": {
        c1: "aaaa",
        c2: "bbbb",
        c7: "ffff"
    },
    "b": {
        c1: "ccc",
        c2: "dddd",
        c10: "tttt"
    },
    "c": {
        c1: "ffff",
        c2: "kkkk",
        c3: "mmmm"
    }
};

for(let k in mass)
  console.log(mass[k].c1);
