How to check if current time falls within a specific range considering also minutes

Question

I am doing a Website for Restaurants Home Delivery ,depending on Restaurant's Home Delivery Timings i need to enable / disable Order Now Button

I have got startTime and End Time in 12 Hour format .

This is the code

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());

I need to check if the current time is in between startTime and EndTime or not

If its only Hours ,i could have extracted the first character before colon from startTime ,endTime and currentTime and done a comparision like this

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

But i need to take the minutes also in consideration ,so could you please let me how to do this comparsion if minutes were takein in consideration ??

Answer 1

Something like this should work

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}

It splits those times and adds 12 to PM times, then creates date objects that can easily be compared.
