javascript - 无法将多维数组重组为一维数组吗？

Question

我有 header field 数组和用户 info 数组，所以我需要重新排列新的一个多数组。我想设置 field 数组值到新键。将 0 的 info 索引移动到“姓名”下，1 移动到“年龄”，2 移动到“性别”...

var customer = [];

var field = ["Name","Age","Gender"];

var info = [
 ["David","32","Male"],
 ["John","35","Male"],
 ["Enna","28","Female"],
 ["Watson","22","Female"]
 ];

info.map(function(each,i){
each.map(function(data,index){
  customer[field[index]] = data;
});
});

console.log(customer);//[Name: "Watson", Age: "22", Gender: "Female"]

但是，我只是得到数组就像上面的 console.log

如何输出这样的，我不知道

// ["Name"] :["David","John","Enna","Watson"]
// ["Age"] :["32"],["35"],["28"],["22"]
// ["Gender"] :["Male"],["Male"],["Female"],["Female"]

Answer 1

这是您正在寻找的答案

    var customer = {};

var field = ["Name","Age","Gender"];

var info = [
 ["David","32","Male"],
 ["John","35","Male"],
 ["Enna","28","Female"],
 ["Watson","22","Female"]
 ];

info.map(function(each,i){
    each.map(function(data,index){
        if (!customer[field[index]])customer[field[index]] = []
        customer[field[index]].push(data);
    });
});
console.log(customer);

//sample output  
{ Name: [ 'David', 'John', 'Enna', 'Watson' ],
  Age: [ '32', '35', '28', '22' ],
  Gender: [ 'Male', 'Male', 'Female', 'Female' ] }
