How can I humanize this complete duration in moment.js / javascript
提问by gordyr
I have a 'time remaining' counter in place for file uploads. The remaining duration is calculated and converted into milliseconds like so:
我有一个用于文件上传的“剩余时间”计数器。剩余的持续时间被计算并转换为毫秒，如下所示：
var elapsedTime = e.timeStamp - timestarted;
var speed = e.loaded / elapsedTime;
var estimatedTotalTime = e.totalSize / speed;
var timeLeftInSeconds = (estimatedTotalTime - elapsedTime) / 1000;
I then build an array which I intend to build into a humanized string. The array is as follows:
然后我构建了一个数组，我打算将它构建成一个人性化的字符串。数组如下：
var time = {
years : Math.round(moment.duration(timeLeftInSeconds, 'milliseconds').years()),
months : Math.round(moment.duration(timeLeftInSeconds, 'milliseconds').months()),
days : Math.round(moment.duration(timeLeftInSeconds, 'milliseconds').days()),
hours : Math.round(moment.duration(timeLeftInSeconds, 'milliseconds').hours()),
minutes : Math.round(moment.duration(timeLeftInSeconds, 'milliseconds').minutes()),
seconds : Math.round(moment.duration(timeLeftInSeconds, 'milliseconds').seconds())
};
This all works perfectly and if I output a string representation of this data like so:
这一切都很完美，如果我像这样输出这个数据的字符串表示：
console.log(time.years + ' years, ' + time.months + ' months, ' + time.days + ' days, ' + time.hours + ' hours, '+ time.minutes + ' minutes, ' + time.seconds + ' seconds');
I it returns a nice simple stream of remaining time like so:
它返回一个不错的简单剩余时间流，如下所示：
0 years, 0 months, 0 days, 0 hours, 1 minutes, 7 seconds
What I now need to do is humanize this output so that the string is built dependent on the time remaining. e.g
我现在需要做的是人性化这个输出，以便根据剩余时间构建字符串。例如
- 2 years and 3 months remaining
- 1 hour, 32 minutes and 41 seconds remaining
- 7 seconds remaining
- 3 minutes 46 seconds remaining
- 6 seconds remaining
- 还剩2年3个月
- 还剩 1 小时 32 分 41 秒
- 剩余 7 秒
- 剩余 3 分 46 秒
- 还剩 6 秒
etc...etc...
等等……等等……
Now I know that moment.js has the abiility to automatically humanize durations which works fine for single values but this can have multiple possible values ( hours/minutes/seconds etc)
现在我知道 moment.js 具有自动人性化持续时间的能力，这对单个值工作正常，但这可以有多个可能的值（小时/分钟/秒等）
How can I go about humanizing this data either with moment.js or by manually building the string?
我如何使用 moment.js 或手动构建字符串来人性化这些数据？
Thanks in advance.
提前致谢。

I think your best bet would be something like this:
我认为你最好的选择是这样的：
function humanize(time){
if(time.years > 0){ return time.years + ' years and ' + time.months + ' months remaining';}
if(time.months > 0){ return time.months + ' months and ' + time.days + ' days remaining';}
if(time.days > 0){ return time.days + ' days and ' + time.hours + ' hours remaining';}
if(time.hours > 0){ return time.hours + ' hours and ' + time.minutes + ' minutes and ' + time.seconds + ' seconds remaining';}
if(time.minutes > 0){ return time.minutes + ' minutes and ' + time.seconds + ' seconds remaining';}
if(time.seconds > 0){ return time.seconds + ' seconds remaining';}
return "Time's up!";
}
Alternatively, you could use this function:
或者，您可以使用此功能：
function humanize(time){
var o = '';
for(key in time){
if(time[key] > 0){
if(o === ''){
o += time[key] + ' ' + key + ' ';
}else{
return o + 'and ' + time[key] + ' ' + key + ' remaining';
}
}
}
return o + 'remaining';
}
It returns "x <time> and y <time> remaining", for the 2 greatest values. (Or only seconds in the last case.
"x <time> and y <time> remaining"对于 2 个最大值，它返回。（或者在最后一种情况下只有几秒钟。

My HumanizeDuration.jslibrary sounds like exactly what you want:
我的HumanizeDuration.js库听起来正是您想要的：
humanizeDuration(1); // "1 millisecond"
humanizeDuration(3000); // "3 seconds"
humanizeDuration(2012); // "2 seconds, 12 milliseconds"
humanizeDuration(97320000); // "1 day, 3 hours, 2 minutes"
Looks like my answer's a bit late, but maybe it'll help others looking at this question!

You should give a try on this plugin: moment-duration-format
你应该试试这个插件：moment-duration-format
Its syntax is very convenient:
它的语法非常方便：
var moment = require('moment');
require("moment-duration-format");
moment.duration(32832, "seconds").format("h [hrs]: m [min]: s [sec]")
// => 9 hrs: 7 min: 12 sec"

I ended up being happy with date-fns' formatDistanceToNow. You can add that function without having to add the whole library like moment.js
我最终对 date- fns 的 formatDistanceToNow 感到满意。您可以添加该函数，而无需像 moment.js 那样添加整个库
