Sum between dataslotes type Date in a String


Sum between dataslotes type Date in a String

  • In a project i got 3 dataslots. 2 dates and 1 string.

    Got 2 dates and what a number of days between those to in an string field (or other type if String does not work.

    Date 1 = 03-01-2010

    Date 2 = 01-01-2010

    String 1 = 2

    so there are 2 days between the dates.

    OnChange of one of those days a string value has to be calculate the number of days between de dates fields.

    How can i handle this

  • Hello Danny,

    You may use the following pre/post script for your requirement:


    var d1=jst.getDataSlotValue("Date1");
    var d2=jst.getDataSlotValue("Date2");
    var d3=d1-d2;
    var d4=d3/(1000*60*60*24);
    var d5=Math.round(d4);
    jst.putDataSlot("numDS", d5);


    Where Date1, Date2 are the date dataslot and numDS is Number dataslot.



  • Deepak,

    Thanks voor the quick reply!

    But i'm sorry to say i still can't get it working.

    I used this:

    var d1 = sbm.util.getValue('endDate');
    var d2 = sbm.util.getValue('tolerenceDate');
    var d3 = d1-d2;
    var d4 = d3/(1000*60*60*24);
    var d5 = Math.round(d4);

    Note: i use a WebApplication so don't think i can use the jst. syntax?!

    Is there also a date without the time available?



  • Yes. date dataslot is of two types,

    1. Date and Time. 

    2. Date Only.

    This date configuration can be selected in BPM Studio> Application> Dataslots tab>> double click> Default Format tab>Type.

    In case if you face any issues, please send me your test application and i will modify it as per your requirement.

    Thank you,


  • Thanks Parshuram,

    The date is now without Time.

    But still got the problem with de sum between the 2 dates in my webapplication.



  • Please try below code,

    var t1 = new Date(document.form.d1.value);
    var t2 = new Date(document.form.d2.value);
    var t3 = t1-t2;
    var t4 = t3/(1000*60*60*24);
    var t5 = Math.round(t4);

    d1 and d2 are date dataslot names. Please find attached sample application and let me know it helps.
