Incremental dates in fields based on a manual date input in a "StartDate" field

[Getve]

I have this form with a start date that need to be manually input by the users. Based on that date, the fields 1 to 4 should be filled automagically with the "StartDate"+0,  "StartDate"+1, "StartDate"+2, "StartDate"+3, (...). How do I solve that with a Java script in Acrobat?

I'm thankfull for any help here!

Use this code as the custom calculation script of your fields:

var startDateString = this.getField("StartDate").valueAsString;
if (startDateString=="") event.value = "";
else {
    var startDate = util.scand("dd.mm.yy", startDateString);
    startDate.setDate(startDate.getDate()+0); // change 0 to 1, 2, 3, etc. for the other fields
    event.value = util.printd("dd.mm.yy", startDateString)
}

If you're interested, I've also developed a (paid-for) tool that allows you to set up such calculations very easily: Custom-made Adobe Scripts: Acrobat -- Apply Automatic Date Calculation

Hi try67 & thanks!

Your code solved my challenge after a small adjustment. I changed startDate to startDateString in line 04 and 05 (as below) and voila; it worked!

var startDateString = this.getField("StartDate").valueAsString;
if (startDateString=="") event.value = "";
else {
    var startDateString = util.scand("dd.mm.yy", startDateString);
    startDateString.setDate(startDate.getDate()+0); // change 0 to 1, 2, 3, etc. for the other fields
    event.value = util.printd("dd.mm.yy", startDateString)
}

I'll certainly check out your tool if this scrifpting thing is getting a habbit... Again, thank you very much - brilliant!
