Resolved JavaScript works in Foxit but not in Adobe Reader - Foxit PDF Editor for Mac

[cwb162]

Hi,

I have written a few scripts to automate dates and checking if required fields have been filled when someone clicks to sign the PDF and they work fine on Foxit PDF Editor for Mac on my Macbook M1 Pro and they work when I switch to Parallels Windows and run Foxit PDF Editor Pro. But, when I use Adobe Reader on either OS the JS does not work. I have attached my pdf for reference.

I've reported the mentioned issue to our JS engineer for further advise. Also, would you please reporting this issue to Adobe support as well to see where the problem could be and check if there's any setting that prevents the JS from runing in Adobe?

Thank you.

The bug is in your scripts.


When I open your document with Acrobat Reader the JavaScript Console show this message:

SyntaxError: missing ; before statement
2:Document-Level:Dates

And when I click in the Date field the JavaScript Console show this message:

ReferenceError: Dates is not defined
1:Field:Mouse Down

I did not go further, there may be other errors...

Okay, thanks cherry. I will send something to them.

I changed a few settings and I see this now in Adobe. I cannot find where the error is and Foxit does not give me the same warning...

Date: I cannot understand your script, I changed it for a simpliest one.

Required: I replaced all "let" by "var".



Now it works fine.

Thank you for your sharing.

Can you give it a try to see if it helps?

That did the trick! Here's a quote from an Adobe community member:

Your script uses clever ECMAscript 6 code tricks including let and interpolated expressions in back tick string literals. But Acrobat doesn't use such a recent language base. Stick to the traditional basics.

So, do not use "let" or "const," only "var," and do not use string backticks (``) as in JS6.
