我正在尝试在本机上进行即将发生的事件，我有这个对象
const calendatData = [
{
"data": [
{
"id": 25,
"title": "Spotify",
"name": "Family",
"service_id": 1,
"repetition": "Monthly",
"price": "79000",
"upcoming_date": [
"2020-08-07T13:35:44.606Z"
]
},
{
"id": 26,
"title": "Netflix",
"name": "Mobile",
"service_id": 2,
"repetition": "Monthly",
"price": "49000",
"upcoming_date": [
"2020-08-18T13:35:44.600Z",
"2020-08-07T13:35:44.606Z"
]
},
{
"id": 27,
"title": "iTunes",
"name": "Weekly Special",
"service_id": 3,
"repetition": "Weekly",
"price": "22000",
"upcoming_date": [
"2020-08-07T13:35:44.606Z",
"2020-08-14T13:35:44.606Z",
"2020-08-21T13:35:44.606Z",
"2020-08-28T13:35:44.606Z"
]
}
],
"status": "success"
}
]
我一直试图做的是基于提取对象upcoming_date。我需要的结果是这样的
upcomingData = [
{
date: '2020-08-07',
title: [
'Spotify',
'Netflix',
'iTunes'
]
},
{
date: '2020-08-18',
title: ['Netflix']
},
{
date: '2020-08-14',
title: ['iTuunes']
},
{
date: '2020-08-21',
title: ['iTuunes']
},
{
date: '2020-08-28',
title: ['iTuunes']
}
]
在同一日期，如果有多个标题，则应在对象中的同一日期下将其分组。
相反，我得到的是这个物体
upcomingData = [
{
title: [
"Spotify",
"Netflix",
"iTunes",
],
date : [
"2020-08-29",
"2020-08-07",
"2020-08-18",
"2020-08-07",
"2020-08-07",
"2020-08-14",
"2020-08-21",
"2020-08-28",
]
}
]
我对此并不陌生，并且我知道这主要是关于javascript的知识，我们将不胜感激。
谢谢
你可以
Array.prototype.reduce()建立Map日期字符串的修剪部分用作键，并将所需格式的对象用作值Map值，使用Map.prototype.values()到结果数组中以下是一个快速的实时演示：
const src = [{"data":[{"id":25,"title":"Spotify","name":"Family","service_id":1,"repetition":"Monthly","price":"79000","upcoming_date":["2020-08-07T13:35:44.606Z"]},{"id":26,"title":"Netflix","name":"Mobile","service_id":2,"repetition":"Monthly","price":"49000","upcoming_date":["2020-08-18T13:35:44.600Z","2020-08-07T13:35:44.606Z"]},{"id":27,"title":"iTunes","name":"Weekly Special","service_id":3,"repetition":"Weekly","price":"22000","upcoming_date":["2020-08-07T13:35:44.606Z","2020-08-14T13:35:44.606Z","2020-08-21T13:35:44.606Z","2020-08-28T13:35:44.606Z"]}],"status":"success"}],
result = [...src[0].data
.reduce((r,{upcoming_date, title}) => (
upcoming_date.forEach((s,_,__,date=s.slice(0,10)) =>
r.set(
date,
{date, title: [...(r.get(date)?.title||[]), title]}
)),r),
new Map())
.values()
]
console.log(result).as-console-wrapper{min-height:100%;}本文收集自互联网，转载请注明来源。
