使用javascript查找时间段的持续时间。 [英] Find duration of time period using javascript.

问题描述

我需要分别从当前日期中减去datetimepicker值。



开始日期是我的选择器ID。



我尝试过：

i need to subtract datetimepicker value form current date, separately.

start date is my picker id.

What I have tried:

function getdate() {
        

        var tt = document.getElementById('Startdate').val();
        alert(tt);

        var today = new Date();
        var dd = today.getDate();
        var mm = today.getMonth() + 1;
        var yyyy = today.getFullYear();
        tod = mm + '/' + dd + '/' + yyyy;
      
        
      
    }

推荐答案

因此，JS Date对象基本上只是Unix纪元的毫秒数。您可以使用dateObject.getTime（）直接获取此内容。



因此，从当前日期减去datepicker日期：

So, the JS Date object is basically just the number of milliseconds from the Unix epoch. You can directly get this using dateObject.getTime().

Therefore, for subtracting a datepicker date from the current date:

var tt = document.getElementById('Startdate').val();
var diff = Date.now() - new Date(tt).getTime();
var seconds = diff/1000;
var minutes = diff/60000;
var hours = diff/3600000;
var days = diff/86400000;

MDN是JavaScript文档的良好资源：
