Question

Adobe Acrobat Date Calculation

Asked by: bryanpatrick

I have built an Adobe form to display a payment schedule:
Due Date, Payment Amt, Balance

The goal is to have 3 input fields and have the form do the rest.  The input fields are:
Start Date, Monthly Payment, Initial Balance.

I have got everything in place for the Payment Amt and Balance columns including the if statements to determine when the 'loop' is done - but I'm having difficulty with the Due Dates.  I want each payment to be on the same day of each month:
Initial Date: 02/01/2009
Payment2: 03/01/2009
Payment3: 04/01/2009
etc.

Simply adding days or seconds won't suffice since each month has a different length.  I want to add 1 month for each row.

I've seen these sort of Javascript date functions - but they aren't helping me with my month increment project.  

Is there a way to parse out the month value, increment by one and reassemble into a date format?

 

by: HonorGodPosted on 2009-09-01 at 10:54:32ID: 25234062

easily.

What form are you using?

MM/DD/YYYY

DD/MM/YYYY

something else?

What delimiter do you have between the fields?

  / - .

Something else?

 

by: bryanpatrickPosted on 2009-09-01 at 10:55:27ID: 25234070

MM/DD/YYYY

 

by: HonorGodPosted on 2009-09-01 at 11:01:36ID: 25234130

For example, something like this perhaps

<html>
<head>
<script type='text/javascript'>
  function showDate( obj ) {
    var val = obj.value;
    if ( /^(\d{1,2})([-\/.])(\d{1,2})\2(\d{4})$/.test( val ) ) {
      var when = new Date( RegExp.$4, RegExp.$1 - 1, RegExp.$3 );
      alert( 'Valid date: ' + when );
    } else {
      alert( 'Invalid date: "' + val + '"' );
    }
  }
</script>
</head>
<body>
Date: <input type='text' onchange='showDate(this)'>
</body>
</html>

The script is being added to a field in an Adobe Acrobat Form.  So, I stripped out the HTML and the validation.

This is what I was left with:
var val = this.getField("PaymentDate1").value;
      event.value = new Date( RegExp.$4, RegExp.$1 - 1, RegExp.$3 );

I am getting the following error message:
InvalidSetError: Set not possible, invalid or unknown.
Event.value:2:AcroForm:Draft Due DateRow2:Calculate

 

by: HonorGodPosted on 2009-09-01 at 11:29:04ID: 25234467

Well references to RegExp won't work because you discarded the regular expression.  If you know that the data is in MM/DD/YYYY format then try this instead:

var val = this.getField("PaymentDate1").value;
var info = val.split( '/' );
event.value = new Date( info[ 2 ], info[ 0 ] - 1, info[ 1 ] );

My Bad.  Copied it over exactly and I'm getting the following error in the JavaScript debugger:

redeclaration of const info
2:AcroForm:Draft Due DateRow2:CalculateException in line 2 of function top_level, script AcroForm:Draft Due DateRow2:Calculate

redeclaration of const info

by: HonorGodPosted on 2009-09-01 at 11:43:24ID: 25234626

sorry, I didn't know that "info" was a const for your document.

Change the references to "info" in the lines to something else.
Is "data" being used?

Try this:

var val = this.getField("PaymentDate1").value;
var data = val.split( '/' );
event.value = new Date( data[ 2 ], data[ 0 ] - 1, data[ 1 ] );

Just to be sure, I renamed all of the variables:
var val222 = this.getField("Draft Due DateRow1").value;
var data222 = val222.split( '/' );
event.value = new Date( data222[ 2 ], data222[ 0 ] - 1, data222[ 1 ] );

The script was applied to the form field named: Draft Due DateRow2

Got the following error:
Exception in line 3 of function top_level, script Field:Calculate

InvalidSetError: Set not possible, invalid or unknown.
Event.value:3:Field Draft Due DateRow2:Calculate

 

by: HonorGodPosted on 2009-09-01 at 12:44:39ID: 25235182

I wonder if it is complaining about the fact that the values are strings, instead of numerics...

If we subtract 0 from a numeric string, the result should be a numeric...

var val222 = this.getField("Draft Due DateRow1").value;
var data222 = val222.split( '/' );
event.value = new Date( data222[ 2 ] - 0, data222[ 0 ] - 1, data222[ 1 ] - 0 );

What is event?

 

by: bryanpatrickPosted on 2009-09-01 at 13:33:09ID: 25235699

Adobe will take the event.value and place it in the field that contains the Script.

 

by: HonorGodPosted on 2009-09-01 at 13:45:08ID: 25235827

Thanks for that...

Did the suggestion in http:#a25235182 help?

 

by: bryanpatrickPosted on 2009-09-01 at 16:20:41ID: 25237078

You pointed me in the right direction.

I tried a number of things to reduce the number of lines.  Each time, either I would end up with Feb 31st or the rollover from December to January wouldn't work.

var data = this.getField("PaymentDate1").value.split( '/' );
var oldDay = new Date( data[2], data[0] - 1, data[1] );
var oldmonth = oldDay.getMonth()+MonthsInProgram-1;
var newDay = new Date(oldDay.getFullYear(), oldmonth, oldDay.getDate())
var themonth = newDay.getMonth()+1;
event.value = themonth + "/" + newDay.getDate() + "/" + newDay.getFullYear();
