Angular2矩，格式为小时和分钟

Question

我试图通过键解析对象，并将其中一个字段从秒修改为小时+分钟。

tableData[key].forEach(weekday => {
        mappedObject[weekday.day] = weekday.spent;
      });

我已经导入了时刻

import * as moment from 'moment';
import { Moment } from 'moment';

我尝试过

tableData[key].forEach(weekday => {
        mappedObject[weekday.day] = moment.duration(weekday.spent,"seconds").format("h [hrs], m [min]");
      });

但是我发现属性'format'在'Duration'类型上不存在。

我该怎么做才能使其正常工作？

忘了提及：我不允许安装其他外部依赖项。

Answer 1

尝试以下

let duration = moment.duration(500, "seconds");
alert(`${duration.hours()} hours ${duration.minutes()} minutes `);
