Javascript - How to check if current time is between two different times
提问by Matt
I am trying programmatically check if the current time for my web application is between two predefined times. I don't know how to get the current time and then set variables that store two predefined times. The pseudo code would look like this
我正在尝试以编程方式检查我的 Web 应用程序的当前时间是否在两个预定义时间之间。我不知道如何获取当前时间，然后设置存储两个预定义时间的变量。伪代码看起来像这样
if(currentTime < shiftStart && currentTime <shiftEnd)
{
shift = 2
}
But how do I declare and setup the variables so the code works correctly.
但是我如何声明和设置变量以使代码正常工作。

var diff = date.getTime() - (new Date()).getTime();gives you the difference between the time in milliseconds.
var diff = date.getTime() - (new Date()).getTime();以毫秒为单位为您提供时间之间的差异。
var diff1=shiftStart.getTime() - (new Date()).getTime();
var diff2=shiftEnd.getTime() - (new Date()).getTime();
if(diff1 < 0 && diff2 > 0 )
{
shift = 2;
}

var now = Date.now();
var time1 = //whatever time1 is
var time2 = //whatever time2 is
if (now > time1 && now < time2)
{
alert("blah"):
}
