日期时差(小时)-Angular 2 [英] Date difference in hours - Angular 2

问题描述

如何获取angular2中两个日期之间的小时数差异?我不想使用像moment.js这样的外部库.

How can I get difference in hours between two dates in angular2? I don't want to use external libs like moment.js.

例如，具有 incidentTime ='2017-03-05 11:26:16 AM'和 creationTime ='2017-03-06 12:26:16 AM'

let time = +params.data.incidentTime - +params.data.creationTime;  
console.log("time: " + time);

应该返回25小时，但返回NaN.

It should return 25 hours, but It returns NaN.

推荐答案

这应该可以完成:

const date1 = params.data.incidentTime;
const date2 = params.data.creationTime;

const diffInMs = Date.parse(date2) - Date.parse(date1);
const diffInHours = diffInMs / 1000 / 60 / 60;

console.log(diffInHours);

使用Math.floor将结果四舍五入，或将Math.ceil进行四舍五入

Use Math.floor to round the result down, or Math.ceil to round it up
