javascript - 将json多维转换为数组javascript

Question

我想将 Json 数据转换为数组 Javascript，我可以像使用数组 [0][0] 一样访问它，请有人帮助我。

[
    {
        "Login": "test1",
        "Nom": "test1",
        "Prenom": "test1p",
        "password": "124564",
        "Email": "test1@gmail.com"
    },
    {
        "Login": "test2",
        "Nom": "test2",
        "Prenom": "test2p",
        "password": "124564",
        "Email": "test2@gmail.com"
    }
]

我尝试了这段代码，但没有任何反应，我无法使用例如数组 [0][1] 访问数组中的特定(示例，我想拥有 Nom)数据。

代码.js

var data = [
    {
        "Login": "test1",
        "Nom": "test1",
        "Prenom": "test1p",
        "password": "1267846",
        "Email": "test1@gmail.com"
    },
    {
        "Login": "test2",
        "Nom": "test2",
        "Prenom": "test2p",
        "password": "124494",
        "Email": "test2@gmail.com"
    }
];

function data_to_array(data) {
    var array = [];
    for (var key in data) {
        var value = data[key];
        if (typeof value === 'string') {
            array[key] = value;
        } else {
            array[key] = data_to_array(value);
        }
    }
    return array;
}

var array = data_to_array(data);
for(var i in array)
    console.log(array[i]);   

解析后，如果我尝试使用 myArr[0][1] 访问它，它会显示为未定义。

var arr = [];

for (var i=0, len=data.length, tmp; i<len; i++) {
  tmp = [];
  for (var k in data[i]) {
    if (data[i].hasOwnProperty(k)) {
      tmp.push(data[i][k]);
    }
  }
  arr.push(tmp);
}

arr;
// [
//   ["test1","test1","test1p","124564","test1@gmail.com"],
//   ["test2","test2","test2p","124564","test2@gmail.com"]
// ]

如果可以依赖es5函数，可以使用Array.prototype.map和Object.keys

var arr = data.map(function(e) {
  return Object.keys(e).map(function(k) { return e[k]; });
});

arr;
// [
//   ["test1","test1","test1p","124564","test1@gmail.com"],
//   ["test2","test2","test2p","124564","test2@gmail.com"]
// ]
