检查当前时间是否在JavaScript中的两个给定时间之间 [英] Check if current time is between two given times in JavaScript

问题描述

我有两个变量，分别称为 startTime和 endTime。
我需要知道当前时间是否介于startTime和EndTime之间。我该如何仅使用JavaScript？

I have two variables called 'startTime' and 'endTime'. I need to know whether current time falls between startTime and EndTime. How would I do this using JavaScript only?

var startTime = '15:10:10';
var endTime = '22:30:00';
var currentDateTime = new Date(); 
//is current Time between startTime and endTime ???

UPDATE 1 ：

我能够使用下面的代码来获得它。您可以在以下位置查看代码： https://jsfiddle.net/sun21170/d3sdxwpb/1/

I was able to get this using following code. You can check out the code at: https://jsfiddle.net/sun21170/d3sdxwpb/1/

var dt = new Date();//current Date that gives us current Time also

var startTime = '03:30:20';
var endTime = '23:50:10';

var s =  startTime.split(':');
var dt1 = new Date(dt.getFullYear(), dt.getMonth(), dt.getDate(),
                   parseInt(s[0]), parseInt(s[1]), parseInt(s[2]));

var e =  endTime.split(':');
var dt2 = new Date(dt.getFullYear(), dt.getMonth(),
                   dt.getDate(),parseInt(e[0]), parseInt(e[1]), parseInt(e[2]));

alert( (dt >= dt1 && dt <= dt2) ? 'Current time is between startTime and endTime' : 
                                  'Current time is NOT between startTime and endTime');
alert ('dt = ' + dt  + ',  dt1 = ' + dt1 + ', dt2 =' + dt2)

推荐答案

var startTime = '15:10:10';
var endTime = '22:30:00';

currentDate = new Date()   

startDate = new Date(currentDate.getTime());
startDate.setHours(startTime.split(":")[0]);
startDate.setMinutes(startTime.split(":")[1]);
startDate.setSeconds(startTime.split(":")[2]);

endDate = new Date(currentDate.getTime());
endDate.setHours(endTime.split(":")[0]);
endDate.setMinutes(endTime.split(":")[1]);
endDate.setSeconds(endTime.split(":")[2]);


valid = startDate < currentDate && endDate > currentDate
