如何将嵌套数组对转换为数组中的对象 [英] How to convert nested array pairs to objects in an array

问题描述

我的任务是将以下数组转换为对象对数组:

var arr = [[['名字'，'乔']，['姓氏'，'吹']，['年龄', 42],['角色'，'职员']，[['名字'，'玛丽']，['姓氏'，'詹金斯']，['年龄', 36],['角色'，'经理']]]]

我需要将 arr 转换成如下所示的对象数组:

<预><代码>[{firstName:'Joe'，lastName:'Blow'，年龄:42，角色:'clerk'}，{名字:'玛丽'，姓氏:'詹金斯'，年龄:36，角色:'经理'}]

解决方案

程序化解决方案(也可在 https://jsfiddle.net/edorka/jnLxyzhb/):

var arr = [[ ['firstName', 'Joe'], ['lastName', 'Blow'], ['age', 42], ['role', 'clerk']],[['firstName', 'Mary'], ['lastName', 'Jenkins'], ['age', 36], ['role', 'manager'] ]];var 空 = {};var 结果 = arr.map(function(objectArray){var object = this;var 属性 = objectArray.map(function(attrArray){var name = attrArray[0], value = attrArray[1];对象[名称] = 值；返回对象；}， 目的);返回这个；}， 空的);控制台日志(结果)；

I have been tasked to convert the following array to an array of object pairs:

var arr = [
  [
    ['firstName', 'Joe'],
    ['lastName', 'Blow'],
    ['age', 42],
    ['role', 'clerk'],
    [
      ['firstName', 'Mary'],
      ['lastName', 'Jenkins'],
      ['age', 36],
      ['role', 'manager']
    ]
  ]
]

I need to transform arr into an array of objects that looks like this:

[
 {firstName: 'Joe', lastName: 'Blow', age: 42, role: 'clerk'},
 {firstName: 'Mary', lastName: 'Jenkins', age: 36, role: 'manager'}
]

解决方案

Programmatic solution (available too at https://jsfiddle.net/edorka/jnLxyzhb/):

var arr = [[ ['firstName', 'Joe'], ['lastName', 'Blow'], ['age', 42], ['role', 'clerk']], [['firstName', 'Mary'], ['lastName', 'Jenkins'], ['age', 36], ['role', 'manager'] ]];

var empty = {};
var result = arr.map(function(objectArray){
    var object = this;
    var attribute = objectArray.map(function(attrArray){
        var name = attrArray[0], value = attrArray[1];
        object[name] = value;
        return object;
    }, object);
    return this;
}, empty);

console.log(result);
