如何检查是否当前时间落入特定的范围也在考虑分钟

Question

我做了餐馆送货到家网站，根据餐厅的宅配时序我需要启用/禁用现在订购按钮

我有开始时间和12小时制结束时间。

这是代码

var startTime = '8:30 AM' ; 
var endTime = '6:30 PM' ; 


var formatTime = (function() { 
    function addZero(num) { 
     return (num >= 0 && num < 10) ? "0" + num : num + ""; 
    } 
    return function (dt) { 
     var formatted = ''; 

     if (dt) { 
      var hours24 = dt.getHours(); 
      var hours = ((hours24 + 11) % 12) + 1; 
      formatted = [formatted, [addZero(hours), addZero(dt.getMinutes())].join(":"),hours24>11?"pm" :"am"].join(" ");    
     } 
     return formatted; 
    } 
})(); 


var currentTime = formatTime(new Date()); 

我需要检查，如果当前时间是在开始时间和结束时间或不之间

如果只有个小时，我可以从结肠之前提取的第一个字符开始时间，结束时间和currentTime的，做这样的

if(currentTime >= startTime && currentTime <= endTime) 
{ 
alert('Restaurant Open'); 
} 
else 
{ 
alert('Restaurant Closed'); 
} 

一对比，但我需要拿分也考虑到，所以请你让我怎么做T他的比较，如果分钟考虑在内？

如何检查是否当前时间在特定的范围内，还要考虑分钟

Answer 1

像这样的东西应该工作

var startTime = '6:30 PM'; 
 
var endTime = '8:30 AM'; 
 
var now  = new Date(); 
 

 
var startDate = dateObj(startTime); // get date objects 
 
var endDate = dateObj(endTime); 
 

 
if (startDate > endDate) { // check if start comes before end 
 
    var temp = startDate; // if so, assume it's across midnight 
 
    startDate = endDate; // and swap the dates 
 
    endDate = temp; 
 
} 
 

 
var open = now < endDate && now > startDate ? 'open' : 'closed'; // compare 
 
console.log('Restaurant is ' + open); 
 

 
function dateObj(d) { // date parser ... 
 
    var parts = d.split(/:|\s/), 
 
     date = new Date(); 
 
    if (parts.pop().toLowerCase() == 'pm') parts[0] = (+parts[0]) + 12; 
 
    date.setHours(+parts.shift()); 
 
    date.setMinutes(+parts.shift()); 
 
    return date; 
 
}

.as-console-wrapper {top : 0!important}

它分裂的时间，并增加了12 PM倍，然后创建可轻松比较的日期对象。

似乎不适用于午夜过后的时间，请尝试将时间从下午6:30改为上午2:30。一个好的解决方案是使用momentjs随刻范围插件

function inTimeRange(time, startTime, endTime) 
{ 
//Setup today vars 
var today = new moment(new Date()); 
var ayear = today.year(); 
var amonth = today.month() + 1; // 0 to 11 
var adate = today.date(); 
amonth = String(amonth).length < 2 ? "0" + amonth : amonth; 
adate = String(adate).length < 2 ? "0" + adate : adate; 

//Create moment objects 
var moment1, moment2; 
var temp = endTime.split(" "); 
if(temp[1].toLowerCase() == "am") 
{ 
    var test1 = ayear + "-" + amonth + "-" + adate + " " + startTime; 
    var test2 = ayear + "-" + amonth + "-" + adate + " " + endTime; 

    //Make sure that both times aren't morning times 
    if(moment(test2).isAfter(test1)) 
    { 
     var moment1String = ayear + "-" + amonth + "-" + adate + " " + startTime; 
     var moment2String = ayear + "-" + amonth + "-" + adate + " " + endTime; 
    } 
    else 
    { 
     var moment1String = ayear + "-" + amonth + "-" + adate + " " + startTime; 
     var moment2String = ayear + "-" + amonth + "-" + (adate + 1) + " " + endTime; 
    } 

    moment1 = moment(moment1String,  "YYYY-MM-DD HH:mm A"); 
    moment2 = moment(moment2String,  "YYYY-MM-DD HH:mm A"); 
} 
else 
{ 
    var moment1String = ayear + "-" + amonth + "-" + adate + " " + startTime; 
    var moment2String = ayear + "-" + amonth + "-" + adate + " " + endTime; 
    moment1 = moment(moment1String,  "YYYY-MM-DD HH:mm A"); 
    moment2 = moment(moment2String,  "YYYY-MM-DD HH:mm A"); 
} 

//Run check 
var start = moment1.toDate(); 
var end = moment2.toDate(); 

var when; 
if(String(time).toLowerCase() == "now") 
{ 
    when = moment(new Date()); 
} 
else 
{ 
    var timeMoment1String = ayear + "-" + amonth + "-" + adate + " " + time; 
    when = moment(timeMoment1String); 
} 

var range = moment().range(start, end); 
return when.within(range); 
}

var startTime = '02:30 AM'; 
 
var endTime = '13:00 PM'; 
 

 

 

 
var now  = new Date(); 
 
var startDate = dateObj(startTime); 
 
var endDate = dateObj(endTime); 
 

 
alert(endDate) 
 

 
var open = now < endDate && now > startDate ? 'open' : 'closed'; 
 
alert('Restaurant is ' + open); 
 

 
function dateObj(d) { 
 
    var parts = d.split(/:|\s/), 
 
     date = new Date(); 
 
    if (parts.pop().toLowerCase() == 'pm') parts[0] = (+parts[0]) + 12; 
 
    date.setHours(+parts.shift()); 
 
    date.setMinutes(+parts.shift()); 
 
    return date; 
 
}

var startTime = '8:30 AM'; 
 
var endTime = '6:30 PM'; 
 

 
var now  = new Date(); 
 
var startDate = dateObj(startTime); 
 
var endDate = dateObj(endTime); 
 

 
var open = now < endDate && now > startDate ? 'open' : 'closed'; 
 
alert('Restaurant is ' + open); 
 

 
function dateObj(d) { 
 
    var parts = d.split(/:|\s/), 
 
     date = new Date(); 
 
    if (parts.pop().toLowerCase() == 'pm') parts[0] = (+parts[0]) + 12; 
 
    date.setHours(+parts.shift()); 
 
    date.setMinutes(+parts.shift()); 
 
    return date; 
 
}
