Question

I have a question about javascript time ranges

i have two input boxes, the client can give start date and end date

below have 3 seasons with date ranges,i need to count the cost for the user entered date range with
the mapping with below seasons with prices

Total is 3 seasons, below is the date ranges:

Low Season

1st May to 30th June
1st September to 14th December

Cost: $5 per day

---

High Season

11th January to 30th April
1st July to 31st August

Cost: $10 per day

---

Peak Season

-15th December – 10th January
Cost: $2 per day

i write a code for get the date inputs

$('#calculate').click(function(){
//get the first date
da=$('#daydropdowna').val();
ma=$('#monthdropdowna').val();
ya=$('#yeardropdowna').val();



//get the secnd date
dd=$('#daydropdownd').val();
md=$('#monthdropdownd').val();
yd=$('#yeardropdownd').val();



var oneDay = 24*60*60*1000; 
var ourstart= new Date(ya,ma,da);
var oursend= new Date(yd,md,dd);


/*
11th January to 30th April 
1st July to 31st August 
*/
var hsstart= new Date(ya,00,11);
var hsend= new Date(ya,03,11);
var hsstart1= new Date(ya,06,01);
var hsend1= new Date(ya,07,31);


/*
1st May to 30th June 
1st September to 14th December 
*/

var lsstart=new Date(ya,04,01);
var lsend=new Date(ya,05,30);
var lsstart1=Date(ya,08,01);
var lsend1=new Date(ya,11,14);


/*
-15th December - 10th January 
*/
var psstart=new Date(ya,11,15);
var psend=new Date(ya+1,00,10);


var myDate = ourstart;
var myDate1 = oursend;




var startDate = hsstart
var endDate = hsend



//the date range within one high season

if ((startDate < myDate) && (myDate < endDate) && (startDate < myDate1) && (myDate1 < endDate)) {
        alert('seasn 1 h');
       var diffDays = Math.round(Math.abs((myDate1 .getTime() - myDate .getTime())/(oneDay)));

alert (diffDays);
}


//the date range within secnd high season
var startDate = hsstart1
var endDate = hsend1

if ((startDate < myDate) && (myDate < endDate) && (startDate < myDate1) && (myDate1 < endDate)) {
        alert('seasn 2 h');
       var diffDays = Math.round(Math.abs((myDate1 .getTime() - myDate .getTime())/(oneDay)));

alert (diffDays);
}


//the date range within first low season
var startDate = lsstart
var endDate = lsend

if ((startDate < myDate) && (myDate < endDate) && (startDate < myDate1) && (myDate1 < endDate)) {
        alert('season 1 l');
       var diffDays = Math.round(Math.abs((myDate1 .getTime() - myDate .getTime())/(oneDay)));

alert (diffDays);
}



//the date range within second low season
var startDate = lsstart1
var endDate = lsend1



if ((startDate < myDate) && (myDate < endDate) && (startDate < myDate1) && (myDate1 < endDate)) {
        alert('season 2 l');
       var diffDays = Math.round(Math.abs((myDate1 .getTime() - myDate .getTime())/(oneDay)));

alert (diffDays);
}

//peak
var startDate = psstart
var endDate = psend

if ((startDate < myDate) && (myDate < endDate) && (startDate < myDate1) && (myDate1 < endDate)) {
        alert('season p');
       var diffDays = Math.round(Math.abs((myDate1 .getTime() - myDate .getTime())/(oneDay)));

alert (diffDays);
}


//if not wihin a specific range cacuate for all











});

so i need to calculate the total price according to the user input, Ex user enters 2012-05-05 – 2013-01-05 this need to calculate price for 3 season dates which is covering the date range. please hep me for solve this problem, thank you…

Answer 1

I’m not going to code for you but here’s the logic:

tempDate = inputStartDate
for each season
    if seasonStart <= tempDate
        if inputEndDate <= seasonEnd
            price = price + (inputEndDate - tempDate) * seasonCost
            break
        else
            price = price + (seasonEnd - tempDate) * seasonCost
            tempDate = seasonEnd + 1 day

price will contain the total cost/day for the entire date range.
