I am in Ionic 3. I have a JSON feed that has lots of questions in it.
I can grab the feed and display all the questions no problems. I just want to validate the answer areas as not null or not empty. I can target a field like a username or password by name, no problems. In PHP/HTML I'd use a field name of 'answer' and then check each one in turn. I'm just a bit lost as to how to do this in Ionic.
Thanks in advance.
