How can I show a message (alert), if an input field’s value does not meet a condition. For example a city name needs to be unique over all cities, and I want to tell the user that he entered a duplicate city name.
I would like to have this while leaving the input field. Not after a button was clicked…
I looked at your example, thanks for sharing.
You disable the Save when the city is taken.
I Would like to show an alert, to give a message to the user: City is taken.
I already have the alert. I also see how to create the logic to check the existence of of a city. But I don’t see you the raise the alert.
@NigelG: I don’t see a workflow trigger “data has changed”. Would expect it on the input field somewhere…
