Auto populate a PDF with current year to next year using Javascript

[henrykh]

is it possible to auto populate a PDF with the last 2 digits 20__ - 20__ with current year to next year every time I open up a PDF page? example 2017-2018?

You can use this code to populate the whole thing into a field:

var now = new Date();

this.getField("Years").value = "" + now.getFullYear() "-" + (now.getFullYear()+1);

I get a syntaxError: missing ; before statement 2: at line 3 when I put this in the JavaScript Editor. How do I correct that? Thanks for your help.

What exact code did you use?

[henrykh]

I copied & pasted your code exactly into my Acrobat Javascript editor but it returned with that syntaxError:

"missing ; before statement 2: at line 3"

so the code didn't work.

There was a missing "+" in the second line of the code.

var now = new Date();

this.getField("Years").value = "" + now.getFullYear() + "-" + (now.getFullYear()+1);

Another document level script could be:

var now = new Date();

this.getField("Years").value = (now.getFullYear()).concat("-", (now.getFullYear() +1));

You may need to change the field name to match your form.

That didn't work...

I have this JavaScript on Page Properties:

var f = this.getField("Today");

f.value = util.printd("yy", new Date());

so when the page pull up "20__ to 20__" comes up auto populated as "2017 to 20__".

Any way to add another script onto the above so it will show 2017 to 2018?

[gkaiseril · Accepted solution]

You need to add another field and then increment the year value by 1.

A possible script is:

var f = this.getField("Today");

f.value = util.printd("yy", new Date());

f = this.getField("NextYear");

f.value = Number(util.printd("yy", new Date())) + 1;

For this to work one needs to be careful about the type of variables, that is , there is a significant difference between a String variable and a Number variable and how the "+" operator works.

That totally worked! Thank you gkaiseril and try67 for your help!
