when we choose one radio button and click the button, progress bar should be updated each time

I need to create a simple web page which includes three radio button, and three progress bar for each radio button, and one button, if we choose one radio button and click the button, progress bar which belongs to clicked radio button should be updated each time with using ajax, who can help with this issue ?

Here is a sample on how to do this. Note this sample uses setInterval() to simulate an AJAX call
CSS

.my-progress-bar {
  display: none;
  width: 300px;
  text-align: center;
  line-height: 2em;
  border: 1px solid black;
  height: 2em;
  overflow: hidden;
  position: relative;
}
.my-progress-bar span {
  display: block;
  position: absolute;
  right: 100%;
  background: green;
  height: 2em;
  z-index: 50;
  width: 100%;
}
.my-progress-bar b {
  position: relative;
  z-index: 100;
}

  $('button').click(function(e) {
    e.preventDefault();
    var selected = $('.progress-radio:checked');
    $('.progress-bar').hide();
    if (selected.length) {
      // simulate AJAX call here
      var perc = 0;
      var pb = $('#' + selected.data('progress'));
      var slider = pb.find('span');
      pb.css({display: 'inline-block'});
      var text = pb.find('b');
      var intv = setInterval(function() {
        if (perc >= 100) clearInterval(intv);
        text.text(perc + '%');
        var diff = 100 - perc;
        slider.css({right: diff + '%'});
        perc += 10;
      }, 500);
    }
  });

Thanks for your sincere help, but when I choose radio button and click the button, progress bar should be updated its value to one only each time, if I click the button 10 times, progress bar should change its value to 10
