javascript - 如何更改 fromNow 调用的输出？

Question

我使用 moment.js 获取相对时间。例如，它返回“6 小时前”。但我想得到像“6h”这样的短版本。

我阅读了文档:http://momentjs.com/docs/#/customization/relative-time/

但是如果我改变:

moment.updateLocale('en', {
    relativeTime : {
        future: "in %s",
        past:   "%s ago",
        s  : 'a few seconds',
        ss : '%d seconds',
        m:  "a minute",
        mm: "%d minutes",
        h:  "an hour",
        hh: "%d hours",
        d:  "a day",
        dd: "%d days",
        M:  "a month",
        MM: "%d months",
        y:  "a year",
        yy: "%d years"
    }
});

到

moment.updateLocale('en', {
    relativeTime : {
        future: "in %s",
        past:   "%s",
        s  : 'a few seconds',
        ss : '%d h',
        m:  "a minute",
        mm: "%d m",
        h:  "an hour",
        hh: "%d h",
        d:  "a day",
        dd: "%d d",
        M:  "a month",
        MM: "%d m",
        y:  "a year",
        yy: "%d y"
    }
});

我得到错误:

Cannot read property 'humanize' of undefined at Moment.from (moment.js:3313)

当我打电话

moment(value).fromNow()

这里，value是Date类型的日期

是否可以使用 moment.js 获得短格式版本？

Answer 1

我假设您的问题是格式字符串。我用了'hh':

moment.updateLocale('en', {
    relativeTime : {
        future: "in %s",
        past:   "%s ago",
        s  : 'a few seconds',
        ss : '%d seconds',
        m:  "a minute",
        mm: "%d minutes",
        h:  "an hour",
        hh: "%dh",
        d:  "a day",
        dd: "%d days",
        M:  "a month",
        MM: "%d months",
        y:  "a year",
        yy: "%d years"
    }
});

//
// compute six hours ago...
//
 var value = new Date();
value.setHours(value.getHours() - 6);


console.log('With \'hh\' format string: ' + moment(value).fromNow('hh'));
console.log('With no format: ' + moment(value).fromNow());
