Question

I have read this (and other relating things also):

https://developers.google.com/mobile/articles/fast_buttons?hl=fi#conclusion

but I don’t understand how to use this in Google Apps Script. I made the UI with GUI Builder and now I want the buttons to work also on mobile devices.

Could someone please explain to me with a code example of how to change my buttons to work also on mobile devices?

Code that works Ok on PC but not on mobile device:

var handler109 = app.createServerClickHandler('func109');
var but109 = app.getElementById('Button109');
but109.addClickHandler(handler109);

How to use Client Handler? app.createClientHandler(‘func109’) generates an error, app.createClientClickHandler(‘func109’) generates an error… How do I define that function func109 should be called?

var handler109 = app.createClientHandler();
var but109 = app.getElementById('Button109');
but109.addClickHandler(handler109);

Answer 1

First, the article you’ve shared is applicable for mobile and not so much for Google Apps Scripts.

However, the buttons you make in Google Apps Script WILL work on mobile devices too. However, if you only have a server handler set up on the button, it will take a noticeable period of time before the action of the button is seen by the user.

Google Apps Script also has client handlers which you can use which show up a much faster response than server handlers.
