列表到json转换的javascript [英] List to json conversion javascript

问题描述

假设我有两个列表

a= ['apple', 'orange', 'banana']
b= ['red', 'orange', 'yellow']

如何使用第二个列表作为属性名称的指南将其转换为JSON对象?

How can I convert it to a JSON object, using a second list as a guide for the attribute names?

例如，我将定义属性= ['fruit', 'color']

For example, I would define attributes = ['fruit', 'color']

为了获得

result = [
  {fruit: 'apple', color: 'red'}, 
  {fruit: 'orange', color: 'orange'}, 
  {fruit: 'banana', color: 'yellow'}]

推荐答案

如果您可以使用下划线或lodash之类的库(或重新创建此处使用的方法)，则可以这样做:

If you can use a library like underscore or lodash (or recreate the methods used here) it can be done like so:

var attributes = ['fruit', 'color'];
var fruits = ['apple', 'orange', 'banana'];
var colors = ['red', 'orange', 'yellow'];

//Combine arrays in to list of pairs 
//(this would be expanded with each new array of attribute values)
//ORDER IS IMPORTANT
var zipped = _.zip(fruits, colors);

//Map the zipped list, returning an object based on the keys. 
//Remember the order of the arrays in the zip operation 
//must match the order of the attributes in the attributes list
var result = _.map(zipped, function(item, index) {
    return _.object(attributes, item);
});

console.log(result);
