PDF Actions & Custom Keystroke Script

[hari-narendran]

Hi
I came across 2 issues related to text box and checkbox that I need help with.
I have attached a sample PDF with the 2 scenarios

Scenario 1 Text Field :
Text filed has Custom Keystroke Script ( Text Filed Properties -> Custom Keystroke Script ) set to
if ( event.fieldFull ) { this.getField("field_2").setFocus(); }
With this script, text is supposed to overflow from field_1 to filed_2 (works in acrobat). But the overflow doesn't happen extended-pdf-viewer.

Scenario 2 Check Box:
Check box has an Action set to trigger on Mouse Up. Action is to show/hide a field. IN extended-pdf-viewer, show/hide of the filed is not working.

Thanks in advance.

Did you already check if the features work in the showcase of the base library? https://mozilla.github.io/pdf.js/web/viewer.html

I didn't implement the JavaScript engine myself, so I'm afraid I can't help you. But if you can reproduce the same bug at the base library, you can file an issue there, and once the Mozilla team has solved it, I can add it to ngx-extended-pdf-viewer.

I checked the same pdf with pdf.js base library now and I was able to reproduce the issue. I will file an issue there and leave a comment here with the update.
Thanks Stephan.

Sorry that link takes to developer profile. Is there a direct link to the bug ?
Thank you

Oops, sorry - I wanted to make the developer who is most likely to look at your bug aware that you're about to file a bug. I didn't report the bug myself, and I didn't want to confuse you. :)

The fieldFull property exists by itself in the event:

but it isn't used:
