How to find out in js which one the user clicked on??

Answer 1

Depending on how to set the task: if it is important for you to know which user clicked on, then listen to the click event, and if which user selected, then

Array.from(document.getElementsByName('results-tabs')).filter(function(e) { return e.checked })[0];
