PDF timesheet calculation

[MatMan83]

Hi guys!

I am a beginner at this and have searched a lot for anwers but haven´t found any that fits my problem.

I have a PDF form timesheet that uses four time inputs. ex. time1in:07:00, time1out:11:00, time2in:12:00, time2out:16:00. Now I want to sum this up in a total hours field and need help with the script to perform this correctly.

I have found a script that works to sum up the total hours of time1in and time1out but I do not know how to extend the script to also add time2in and time2out to the total sum.

The script I have is:

// start

var start = this.getField("8").value;

var startArr = start.split(":");

// finish

var finish = this.getField("9").value;

var finishArr = finish.split(":");

// difference

var hourDiff = Math.abs(finishArr[0] - startArr[0]);

var minDiff = Math.floor((Math.abs(finishArr[1] - startArr[1]) / 60)*100);

if (minDiff.toString().length == 1)

    minDiff = '0' + minDiff;

var output = hourDiff + "." + minDiff;

event.value = output;

Is there someone who might be able to help me on this one?

It's not about JavaScript or anything to do about programming. It's about how you perform a calculation.

Do this: With pencil and paper, work out the calculation manually. The same way you would do it in a math class. Show all steps.

Sir,

I don't know if I should use military time or regular time . I'm a little rusty on calculations.

Here's what I have;
8 12 1 5 = 8 hrs
12-8 = 4 4*60 = 240 min 240+240 = 480/60 = 8 hrs
5-1= 4 4*60 = 240 min

Now for the half hours
8:00 12:00 13:30 17:00 = 7.5 hrs
12:00-8:00 = 4 hrs
17:00 - 13:30 = 3.5 hrs
17.00*60 = 1020
13.3*60 = 798
1020 - 798 = 222 222/60 = 3.7 hrs

Now for the quarter hours
7:15 12 1 5
12:00 - 7:15 = 4:15
12*60 = 720
7.15*60=429
720-429=291 291+240 = 531 531/60=8.85 hrs ???

8:45 12 1 5
12*60 = 720
8.45*60 = 507
720-507=213 213/60 = 3.55 hrs ??

Sincerely,
Cathy

You should debug your code.
You can display the internal values:

console.show();
console.println("hourDiff: " + hourDiff + " minDiff: " + minDiff);

Bernd,

Thank you!

I’m working on that and reviewing basic javascript. 😊

You must correct the script before you simplify it.

I also need someone to help GIVE me the script for this. I have not clue what I am doing. I am helping my supervisor create a time sheet to help all other employees submit their time with a PDF file. I have Time In, Time Out, Lunch Start, Lunch End, Total Hours. HELP...

Were you able to figure this out?  I need the exact same script that can calculate the total hours worked while deducting for the lunch/break.

I've developed a (paid-for) script that will allow you to do just that:

It can be easily adjusted to deduct the lunch time from the result, too.
