Question

我遇到了一些问题，希望将剩余时间显示为小时和分钟。

现在的问题是，在计算时间时，它显示例如1.97小时。我希望时间像1.30（1小时30分钟）。

我还面临到达时间的问题，我希望将剩余时间计算到下一个open。

下面是我到目前为止完成的代码：

var openTime = [{
    open: -1,
    close: -1
}, {
    open: 8,
    close: 21
}, {
    open: 8,
    close: 21
}, {
    open: 8,
    close: 21
}, {
    open: 8,
    close: 21
}, {
    open: 8,
    close: 21
}, {
    open: 8,
    close: 17
}]

var current = new Date();
var day = current.getDay();
var nextday = current.getDay()+1;
var currentTime = current.getHours() + (current.getMinutes() / 60);
var remainTime = 0;
if (openTime[day].close - (currentTime).toFixed(2) >= 0) {
    remainTime = (openTime[day].close - currentTime).toFixed(2)
console.log("close in %s hours", remainTime);
document.getElementById("hours").innerHTML = "close in " + remainTime+ " hours"
}
else if (openTime[day].close - (currentTime).toFixed(2) <= 0) {
     remainTime = (currentTime).toFixed(2) + (openTime[nextday].open)
document.getElementById("hours").innerHTML = "open in " + remainTime+ " hours"
}

<div id="hours"></div>

Answer 1

function timeConvert(n) {
    var num = n;
    var hours = (num / 60);
    var rhours = Math.floor(hours);
    var minutes = (hours - rhours) * 60;
    var rminutes = Math.round(minutes);
    return num + " minutes = " + rhours + " hour(s) and " + rminutes + " minute(s).";
    }
    console.log(timeConvert(200));

我想你可以这样做。

尝试这样。将您的打开和关闭时间转换为分钟，而当前时间也转换为分钟，并计算剩余时间

var openTime = [{
    open: -1,
    close: -1
}, {
    open: 8,
    close: 21
}, {
    open: 8,
    close: 21
}, {
    open: 8,
    close: 10
}, {
    open: 8,
    close: 21
}, {
    open: 8,
    close: 21
}, {
    open: 8,
    close: 17
}]

var current = new Date();
var day = current.getDay();
var nextday = current.getDay()+1;
var currentTime = currentTime = (current.getHours() * 60) + current.getMinutes();
var remainTime = 0;
var closeTime = (openTime[day].close *60);
var openTime = (openTime[day].open *60);
if (closeTime - currentTime >= 0) {
    remainTime = closeTime - currentTime;
    
console.log("close in %s minutes", remainTime);
var hours = Math.floor(remainTime/60);
  if(hours == 0){
    document.getElementById("hours").innerHTML = "close in " + Math.floor(remainTime%60) + " Mins";
  } else {
    document.getElementById("hours").innerHTML = "close in " + hours+ " hours " + Math.floor(remainTime%60) + " Mins";
  }
}
else if (closeTime - currentTime <= 0) {
     remainTime = currentTime + openTime;
document.getElementById("hours").innerHTML = "open in " + Math.floor(remainTime/60)+ " hours" + Math.floor(remainTime%60) + " Mins";
}

<div id="hours"></div>

请调整关闭功能参数中的关闭时间以进行测试。希望对您有所帮助。

FIDDLE

function closing(closing_time) {
let current_datetime = new Date();
let formatted_date = current_datetime.getFullYear() + "-" + (current_datetime.getMonth() + 1) + "-" + current_datetime.getDate()

var closing = new Date(formatted_date + " "+closing_time);

// get total seconds between the times
var delta = Math.abs(current_datetime - closing) / 1000;

// calculate (and subtract) whole hours
var hours = Math.floor(delta / 3600) % 24;
delta -= hours * 3600;


// calculate (and subtract) whole minutes
var minutes = Math.floor(delta / 60) % 60;
delta -= minutes * 60;

//alert(minutes);

alert("Remaining time to go home : " + hours + "hours " + minutes + "minutes");
}

closing("06:30 PM");

如何计算小时到分钟？
