How to created a nested array of objects using javascript Loop?
问题
我需要循环处理一个AJAX响应，然后创建一个像这样的数组：
"2023-03-30": {"number": '', "url": ""},"2023-03-30": {"number": '', "url": ""}
循环代码如下：
var columns = {};for (var i=0; i < parsed_data.tasks.length; i++) {var mydate = parsed_data.tasks[i].date;columns.push(mydate);}console.log(columns);
但这不会给我所需的结果。
我该如何实现这个？

I need to loop an AJAX response and then create an array like this:
"2023-03-30": {"number": '', "url": ""},"2023-03-30": {"number": '', "url": ""}
The loop looks like this:
var columns = {};for (var i=0; i < parsed_data.tasks.length; i++) {var mydate = parsed_data.tasks[i].date;columns.push(mydate);}console.log(columns);
But this doesn't give me the required result.
How do I achieve this?

以下是翻译好的代码部分：
// 声明一个空对象来存储结果var result = {};// 遍历 AJAX 响应数组for (i = 0; i < parsed_data.tasks.length; i++) {// 从每个对象中提取日期、编号和 URL 值var mydate = parsed_data.tasks[i].date;var number = parsed_data.tasks[i].number;var url = parsed_data.tasks[i].url;// 检查结果对象中是否已存在具有该日期的对象if (!result[mydate]) {// 如果不存在，创建一个新对象，以日期作为键和一个空对象作为值result[mydate] = {};}// 设置结果对象中相应对象的编号和 URL 值result[mydate]["number"] = number;result[mydate]["url"] = url;}// 输出最终结果console.log(result);
英文:
You said you aren't getting the required response. What results are you actually getting? Maybe try something like this.
// Declare an empty object to store the resultvar result = {};// Loop through the AJAX response arrayfor (i = 0; i < parsed_data.tasks.length; i++) {// Extract the date, number, and url values from each objectvar mydate = parsed_data.tasks[i].date;var number = parsed_data.tasks[i].number;var url = parsed_data.tasks[i].url;// Check if an object with the date already exists in the result objectif (!result[mydate]) {// If it doesn't exist, create a new object with the date as the key and an empty object as the valueresult[mydate] = {};}// Set the number and url values for the corresponding object in the result objectresult[mydate]["number"] = number;result[mydate]["url"] = url;}// Output the final resultconsole.log(result);

If you need date you can use Object.keys like:
const array = [{"2023-03-30": {"number": '', "url": ''}},{"2023-03-30": {"number": '', "url": ''}}];const result = array.map(el => Object.keys(el)).flat();console.log(result);
英文:
If you need date you can use Object.keys like:
<!-- begin snippet: js hide: false console: true babel: false -->
<!-- language: lang-js -->
const array = [{"2023-03-30": {"number": '', "url": ""}},{"2023-03-30": {"number": '', "url": ""}}];const result = array.map(el => Object.keys(el)).flat();console.log(result);
<!-- end snippet -->
