Javascript Append JSON Objects
提问by nil
How can I append a JSON like structurewhile iterating through a for loop?
如何在迭代for 循环时附加类似JSON 的结构？
For Example (Pseudo Code):
例如（伪代码）：
var i;
for (i = 0; i < clients.length; i++) {
date = clients.date;
contact = clients.contact;
}
My main goal is to append as many groups of: dates and contacts as the clients.length data holds.
我的主要目标是附加尽可能多的组：日期和联系人作为 clients.length 数据保存。
I need each loop iteration to create something like below of multiple indexes of date and contact groups. My overall goal is to have a data structure like below created through my for loop.
我需要每次循环迭代来创建类似于以下日期和联系人组的多个索引的内容。我的总体目标是通过我的 for 循环创建如下所示的数据结构。
Assume im just using strings for: "Date" & "Contact"
假设我只使用字符串：“日期”和“联系人”
var data = [
{
"Date": "2015-02-03",
"Contact": 1
},
{
"Date": "2017-01-22",
"Contact": 2
}
];

var data = []
function Client(date, contact) {
this.date = date
this.contact = contact
}
clients = new Array();
for (i = 0; i < 4; i++) {
clients.push(new Client("2018-08-0" + i, i))
}
for (i = 0; i < clients.length; i++) {
var dict = {}
dict['Date'] = clients[i].date
dict['Contact'] = clients[i].contact
data[i] = dict
}
console.log(data)

It's a simple push object to array operation. Please try below
这是一个简单的将对象推送到数组的操作。请尝试以下
var data=[];
var i;
for (i = 0; i < clients.length; i++) {
data.push({
date:clients.date,
contact:clients.contact
});
}

(ES6)You can use map function to extract the data you wish, and then convert it to json.
(ES6)你可以使用map函数提取你想要的数据，然后将其转换为json。
let clients = [{date:"", contact:"", otherstuff:""}, {date:"", contact:"", otherstuff:""}]
let clientsMapped = clients.map(client => ({Date:client.date, Contact:client.contact}))
let yourJson = JSON.stringify(clientsMapped)
