如何只显示“今天"而没有其他内容? [英] How to display just 'Today' with nothing else?
问题描述
如果日期时间在今天之内,我只想今天".
I just want 'Today' if the datetime is within today.
moment().calendar() // 'Today at 5:08PM'
推荐答案
使用自定义语言环境.
moment.locale('en-cust', {
calendar: { /*replace calendar format strings*/
lastDay: '[Yesterday at] LT',
sameDay: '[Today]', // <---
nextDay: '[Tomorrow at] LT',
lastWeek: '[last] dddd [at] LT',
nextWeek: 'dddd [at] LT',
sameElse: 'L'
}
});
运行该命令后,moment().calendar();
将返回"Today"
.
After running that, moment().calendar();
will return "Today"
.
所有非日历行为都会保留默认的locale: 'en'
行为.
All non-calendar behaviour will maintain the default locale: 'en'
behaviour.
请注意,您需要替换整个日历对象,而不仅仅是sameDay
属性.
Note that you need to replace the whole calendar object and not just the sameDay
property.
我非常喜欢此解决方案,但它确实依赖于非公开的momentjs api,localeData._calendar
,因为该数据没有吸气剂.它还为extend
使用了jquery,如果您不使用jquery,请告诉我.
I like this solution a lot but it does rely on a non-public momentjs api, localeData._calendar
since there isn't a getter for this data. It also uses jquery for extend
, let me know if you aren't using jquery.
function correctToday(locale,strf){
// copy and extend the locale's calendar data
var localeCal = $.extend({}, moment.localeData(locale)._calendar, {'sameDay':strf});
// Replace the locale's calendar data with the modified one (uses public setter)
moment.locale(locale,{calendar:localeCal});
}
// Usage
correctToday('en',"[today]");
correctToday('fr',"[aujourd'hui]");
和一些测试用例:
moment.locale();
moment().calendar(); //test changes
moment().subtract(22,'hours').calendar(); //test other cal functionality
moment().format(); //test non-cal functionality
moment().fromNow();
// Produces
// ["en", "today", "Yesterday at 12:09 PM", "2015-03-26T10:09:05-04:00", "a few seconds ago"]
// ["fr", "aujourd'hui", "Hier à 12:09", "2015-03-26T10:09:05-04:00", "il y a quelques secondes"]
切换
您可以使用函数代替字符串进行区域设置.因此,上面的correctToday
函数保持不变,但是如果我们想要切换,我们将其命名为:
Toggle
You can use functions in place of strings for locale settings. So, the correctToday
function above remains the same but if we want a toggle, we call it like:
moment.timeOff = true; // this is the toggle, declare it somewhere globally accessible (I'm adding it to moment)
correctToday('en',function(){
return moment.timeOff ? "[today]" : "[today at] LT";
});
如果您不喜欢对"[today at] LT"
进行硬编码,请先存储原始localeData._calendar,然后再进行更改,并从.sameDay
中获取字符串.
If you don't like "[today at] LT"
being hardcoded, store the original localeData._calendar before changing it and take the string from .sameDay
.
