Here is a simple code snippet that should help you achieve this functionality. As mentioned by other practitioners, you set the value of your text input to null in the button's saveInto.

a!localVariables(
  local!text,
  {
    a!textField(
      label: "Input",
      value: local!text,
      saveInto: local!text
    ),
    a!buttonArrayLayout(
      buttons: a!buttonWidget(
        label: "REFRESH INPUT FIELD",
        saveInto: { a!save(local!text, null()) }
      )
    )
  }
)

The value a field shows is stored in a local variable or rule input. To blank the field you need to modify the underlying value using a saveInto.

do you mean like saveInto:{ri!input,

a!save(),a!save()

}?

If for example, you are saving value of the textfield in variable ri!inputText, then within the buttons' saveInto do a!save(ri!nputText,""). now whenever you click on any such button, ri!inputText will become blank.

but this way may cause ri!inputvalue becomes empty to the database right? I just want it to be saved rightly with value plus the textfield to be blank
