Display confirmation popup with JavaScript upon clicking on a link

Question

How do I make one of those hyperlinks where when you click it, it will display a popup asking \"are you sure?\"

Answer 1

try to click, I dare you

with the function

function confirmAction(){
      var confirmed = confirm("Are you sure? This will remove this entry forever.");
      return confirmed;
}

(you can also return the confirm right away, I separated it for the sake of readability)
