角度日期时间格式

Question

我有这个带有日期时间字符串的json数组。我在表格中填充这些数据。

[{"id":8,"startdate":"2018-02-01T00:00:00","enddate":"2018-02-28T23:59:59.9999999","created":"2018-02-15T12:58:43.3417189","filename":"data022018"},{"id":9,"startdate":"2019-03-01T00:00:00","enddate":"2019-03-31T23:59:59.9999999","created":"2019-03-15T12:59:45.1079351","filename":"data032019"},{"id":10,"startdate":"2019-04-01T00:00:00","enddate":"2019-04-30T23:59:59.9999999","created":"2019-04-08T12:58:43.3417189","filename":"data042019"}]

这是我表中的html代码

<td>{{ archive.startdate | date: 'short' }} - {{ archive.enddate | date: 'dd/MM/yyyy' }}</td>

结果是

2/1/18, 12:00 AM - 01/03/2018 (just want to show i format with different methods)
1/4/2018 - 1/5/2018

我真正想要达到的是该月最后一天的最后日期，而不是从下个月的第一天开始。

1/02/2018 - 28/02/2018

我做错了什么？我想结束日期，日期和月份。

感谢@Wandrille的回答

//model
export interface Archive {
    id?: string | number;
    startdate: string | Date; <-- use as string or date object
    enddate: string | Date;
    created: string | Date;
    filename: string;
}

 // component
 this.db.getFiles(
  this.currentPage,
  this.pageSize
  ).subscribe(result => {
    this.totalArchives = result.totalitems;
    this.archives = result.items.map(myitem => ({
      ...myitem,
      startdate: new Date(myitem.startdate), <-- after init as new date, date pipe work as expected
      enddate: new Date(myitem.enddate) <-- date pipe works
    }));
    if(this.totalArchives === '0' || this.totalArchives === 0) {
      this.toastr.info('No Files Yet', 'Waiting for files to generate');
    }

  });

Answer 1

您可以将日期字符串转换为日期。然后，它会工作（也更清洁）

this.archive = this.archive.map(item => (
   {
    ...item,
    startdate : new Date(item.startdate),
    endDate : new Date(item.endDate)
   }
))

Answer 2

这是:之后的价值

试试这样吧

{{ startdate.split(":")[0]| date: 'short'}} 
 <br>
{{ enddate.split(":")[0]| date: 'short'}}
