Hide/Show fields not working on mobile devices

[Ang111]

Hi

I have aline of code that works no problem on desktop. In custom keystroke script:

this.getField("Supply_App.3").display = (event.value=="None") ? display.hidden : display.visible;

This doens't work on a mobile device -I'm testing on an iPad with Acrobate Reader for iOS. I've read I shoudl replace the ? with an if statement but I'm struggling to get it to work correctly without adding an additoanl vaidation field - which I'd rather not do. Any advice?

TIA

I don't think it will make much of a difference, but you can give it a try:

if (event.value=="None") this.getField("Supply_App.3").display =  display.hidden;

else this.getField("Supply_App.3").display =  display.visible;

I would recommend trying it in PDF Expert by Readdle, which currently has the best support for scripts out of all mobile PDF apps.

Thank you. As you thought, the code didn't help on ipad but PDF Expert works well so thank you! On a slightly seperate note, do you know how I can find out why my pdf keeps crashing? Only crashes on a laptop adn when I tab out of a specific field. I've deleted the field and added it back in but still have the same problem. I have opened another thread for that issue but thougth I'd try my luck here too 🙂  Thanks again

Look in the Console window for any reported errors, Ctrl-J

Thanks Thom, I'm not seeing any error there. In fact at the moment it's only crashing when in Reader. I've attached a crash log but I have no idea how to interpret it. Any ideas how I can begin to fault find with this?

Try using PDF Expert on the IPad.  Strangely it has a much better Acrobat JS implementation than Mobile Acrobat.
