我有一个开始日期,时间和结束日期,时间,我也找到了旅行的总持续时间。输出以毫秒为单位,我需要将其转换为小时格式。通过在这里搜索其他答案,我尝试了以下但没有结果。
<md-cell *mdCellDef="let row"> {{row?.duration | formatDuration}} </md-cell>
和ts文件:
export class StoppageComponent implements OnInit {
constructor() {
}
ngOnInit() {
}
filter('formatDuration', function () {
return function (input) {
var totalHours, totalMinutes, totalSeconds, hours, minutes, seconds, result='';
totalSeconds = input / 1000;
totalMinutes = totalSeconds / 60;
totalHours = totalMinutes / 60;
seconds = Math.floor(totalSeconds) % 60;
minutes = Math.floor(totalMinutes) % 60;
hours = Math.floor(totalHours) % 60;
if (hours !== 0) {
result += hours+':';
if (minutes.toString().length == 1) {
minutes = '0'+minutes;
}
}
result += minutes+':';
if (seconds.toString().length == 1) {
seconds = '0'+seconds;
}
result += seconds;
return result;
};
});
}
我认为错误在于ts文件,因为我是角色新手。
使用管道是否有直接转换而不使用函数?

其他答案看起来很复杂,终于找到了解决方案。
Html as,
<md-cell *mdCellDef="let row"> {{getFormathours(row?.duration)}} </md-cell>
和ts,
getFormathours(input) {
var totalHours, totalMinutes, totalSeconds, hours, minutes, seconds, result='';
totalSeconds = input / 1000;
totalMinutes = totalSeconds / 60;
totalHours = totalMinutes / 60;
seconds = Math.floor(totalSeconds) % 60;
minutes = Math.floor(totalMinutes) % 60;
hours = Math.floor(totalHours) % 60;
console.log (hours + ' : ' + minutes + ' : ' + seconds);
if (hours !== 0) {
result += hours+' hr:';
if (minutes.toString().length == 1) {
minutes = '0'+minutes;
}
}
result += minutes+' min';
if (seconds.toString().length == 1) {
seconds = '0'+seconds;
}
result += seconds;
return result;
}
根据我的问题,这给出了我需要的确切输出和更清晰的解决方案。无论如何,我也非常感谢别人的答案。

您无需重新发明轮子。您可以使用Date对象来获取持续时间。
假设您有2个日期对象,
function getTravelDuration(date1, date2) {
var diff = +date2 - +date1;
var today = new Date();
today.setHours(0,0,0,0);
var arrival = new Date(+today + diff);
var duration = ['getFullYear', 'getMonth', 'getDate', 'getHours', 'getMinutes', 'getSeconds'].reduce(function(p,c,i,a){
var value = arrival[c]() - today[c]();
if(value) {
p += value;
p += ((c === 'getFullYear') ? ' Year' : c.replace('get', ' ')) + ' '
}
return p;
}, '');
console.log(duration);
}
function doubleDigits(str){
return ('00' + str).slice(-2)
}
getTravelDuration(new Date(2017, 10, 5, 5), new Date(2017, 10, 5, 15, 23));
getTravelDuration(new Date(2017, 10, 5, 5), new Date(2017, 10, 6, 15, 23, 30));

对我来说,最好的选择(没有错误)是使用时刻库,而不是日期。 请检查https://momentjs.com/docs/
var t1 = moment('2017/10/5 15:23');
var t2 = moment('2017/10/5 15:23');
var differenceMinutes = t1.diff(t2, 'minutes');
var differenceMilliseconds = t1.diff(t2, 'minutes');
使用流行且经过测试的库可能会更好。您可以在角度模板中使用:

示例:
{{startDate | amDifference: endDate :'' }}

您可以直接使用此代码
export class StoppageComponent implements OnInit {
constructor() {
}
ngOnInit() {
}
filter('formatDuration', function () {
return function (input) {
var result = new Date(input);
var n = (d.getDate().toString()) +'/'+ (d.getMonth().toString())+'/' +(d.getFullYear().toString()) + ' '+ (d.getHours().toString()) +':'+ (d.getHours().toString()) +':'+ (d.getSeconds().toString());
return result;
};
});
}
