javascript - Progress Bar text

So I have a great progress bar thanks to some of you on stackoverflow. My question is how do I get text to tell the percentage of the progress bar and move with the progress bar (if the green part of the bar is at 50% I want the text to be at 25% ect...i.e always in the middle of the progress)

Thanks!

Use the CSS ::after selector and attr() function for this. The ::after selector appends text to the end of the element, while attr() returns the value of a given attribute.

function update_progressbar() {
  var opt1 = parseInt($('option:selected', $('#FirstQOne')).val());
  var opt2 = parseInt($('option:selected', $('#FirstQTwo')).val());
  var opt3 = parseInt($('option:selected', $('#FirstQThree')).val());
  var opt4 = parseInt($('option:selected', $('#FirstQFour')).val());
  var opt5 = parseInt($('option:selected', $('#FirstQFive')).val());
  var opt6 = parseInt($('option:selected', $('#FirstQSix')).val());
  var opt7 = parseInt($('option:selected', $('#FirstQSeven')).val());
  var opt8 = parseInt($('option:selected', $('#FirstQEight')).val());

  var total = isNaN(opt1) ? 0 : opt1;
  if (!isNaN(opt2)) {
    total += opt2;
  }
  if (!isNaN(opt3)) {
    total += opt3;
  }
  if (!isNaN(opt4)) {
    total += opt4;
  }
  if (!isNaN(opt5)) {
    total += opt5;
  }
  if (!isNaN(opt6)) {
    total += opt6;
  }
  if (!isNaN(opt7)) {
    total += opt7;
  }
  if (!isNaN(opt8)) {
    total += opt8;
  }
  $("#progressBar").prop('value', total)
}

$('#FirstQOne').on('change', update_progressbar);
$('#FirstQTwo').on('change', update_progressbar);
$('#FirstQThree').on('change', update_progressbar);
$('#FirstQFour').on('change', update_progressbar);
$('#FirstQFive').on('change', update_progressbar);
$('#FirstQSix').on('change', update_progressbar);
$('#FirstQSeven').on('change', update_progressbar);
$('#FirstQEight').on('change', update_progressbar);
progress {
  text-align: center;
}

progress:after {
  content: attr(value)'%';
  position: relative;
  top: -1.15em;
}
