setOnChangeAction example

[Paul Armstrong]

Hello

I want to text entered into a TextInput changed to lowercase as the user enters new text (or at least after they have left the field).

An Action function triggered through TextInput::setOnChangeAction(...) does hear the change and the event passed to the Action function has the value I want to change. 

But it is not obvious how to change the value on the original TextInput object. 

function setup() {

  var action = CardService.newAction().setFunction("on_change");

  var text CardService.newTextInput().setOnChangeAction(action);

}

function on_change(event) {

   // do what to change the value of the text object?

}

Thank you!

Hi,

Did you find a way for this?

Hi

Not in real-time, no. I end up doing it after the fact.

I think the closest to being able to do it (as the user types or before they submit the form) would be as per this API and example  https://developers.google.com/apps-script/reference/card-service/text-input?hl=en#setSuggestionsAction(Action) 

Good luck.

I ended up navigating another card with the updated values, though it might not be the correct way to do it.
