我已经实现了一个模块,该模块采用两个moment.js
时间戳和一个舍入规则,并返回这些时间戳之间的舍入moment.js
持续时间。
我的第一个直觉是使用moment.Moment
指定预期的输出类型,如下所示。
export default function roundDuration(
startTime: moment.Moment,
endTime: moment.Moment,
timeRoundingRule: number
): moment.Moment {
const duration = moment.duration(endTime.diff(startTime));
// calculate rounded duration based on rounding rule
return roundedDuration;
}
但是持续时间不同于瞬间。
在我的规格文件中,
import * as moment from 'moment';
import roundDuration from './rounding';
test('roundDuration rounds zero seconds to zero minutes duration using rule UpToNearestMinute', () => {
const startTime = moment('05-17-2018 23:40:00', 'MM-DD-YYYY hh:mm:ss');
const endTime = moment('05-17-2018 23:40:00', 'MM-DD-YYYY hh:mm:ss');
const timeRoundingRule = 0;
const roundedTime = roundDuration(startTime, endTime, timeRoundingRule);
expect(roundedTime.asMinutes()).toBe(0);
});
我收到以下棉绒错误:
[ts] Property 'asHours' does not exist on type 'Moment'. Did you mean 'hours'?
寻找或可以使该错误消失的特定类型定义,例如moment.Moment.duration
或moment.duration
:
export default function roundDuration(
startTime: moment.Moment,
endTime: moment.Moment,
timeRoundingRule: number
): moment.Moment.duration { ... }
收益
[ts] Namespace 'moment' has no exported member 'Moment'.
或
[ts] Namespace 'moment' has no exported member 'duration'.
哪种实现可以纠正这两个错误?
答案 0 :(得分:1)
根据您的导入为import * as moment from 'moment'
,Duration的类型为moment.Duration
,而不是moment.duration
。改变这个
export default function roundDuration(
startTime: moment.Moment,
endTime: moment.Moment,
timeRoundingRule: number
): moment.Moment.duration { ... }
到
export default function roundDuration(
startTime: moment.Moment,
endTime: moment.Moment,
timeRoundingRule: number
): moment.Duration{ ... }
