Countdown clock in JS using HTML and CSS

I want to display a countdown timer and progress bar. I have this javascript code but I can not add css, html and progress bar code to my javascript code.

<script>
var hoursleft =  3;
var minutesleft = 0; 
var secondsleft =  0; 
var finishedtext = "Countdown finished!";
var end1;
if(localStorage.getItem("end1")) {
end1 = new Date(localStorage.getItem("end1"));
} else {
end1 = new Date();
end1.setMinutes(end1.getMinutes()+minutesleft);
end1.setSeconds(end1.getSeconds()+secondsleft);}
var counter = function () {
var now = new Date();
var diff = end1 - now;
diff = new Date(diff);
	var milliseconds = parseInt((diff%1000)/100)
    var sec = parseInt((diff/1000)%60)
    var mins = parseInt((diff/(1000*60))%60)
    var hours = parseInt((diff/(1000*60*60))%24);
if (hours < 10) { 
    hours = "0" + hours;} 
if (mins < 10) {
    mins = "0" + mins;}
if (sec < 10) { 
    sec = "0" + sec;}     
if(now >= end1) {     
    clearTimeout(interval);
    localStorage.setItem("end", null);
     localStorage.removeItem("end1");
     localStorage.clear();
    document.getElementById('divCounter').innerHTML = finishedtext;
     if(confirm("TIME UP!"))
     window.location.href= "result.php";
} else {
    var value = hours+":" +mins + ":" + sec;
    localStorage.setItem("end1", end1);
    document.getElementById('divCounter').innerHTML = value;}}
var interval = setInterval(counter, 1000);
</script>

Maybe I don't understand your question completely. But here are some ideas I would come up with.

  • maybe the html part of your code got lost by copying it into your Post.

  • I assume you understood the Basics about adding a script to html code.

  • I made a super simple example based on your code:

    <html>
  <body>
    <progress id="progressBar" value="22" max="100"></progress>
    <div id="divCounter"></div>
  </body>
</html>

<script>
var hoursleft =  0;
var minutesleft = 5;
var secondsleft =  0;
var finishedtext = "Countdown finished!";
var end1;
var progressBar = document.getElementById('progressBar')
if(localStorage.getItem("end1")) {
  end1 = new Date(localStorage.getItem("end1"));
} else {
  end1 = new Date();
  end1.setHours(end1.getHours()+hoursleft); // Why is this line missing?
  end1.setMinutes(end1.getMinutes()+minutesleft);
  end1.setSeconds(end1.getSeconds()+secondsleft);
}
progressBar.max = end1 - new Date();


var counter = function () {
  var now = new Date();
  var diff = end1 - now;
  diff = new Date(diff);
  var milliseconds = parseInt((diff%1000)/100)
  var sec = parseInt((diff/1000)%60)
  var mins = parseInt((diff/(1000*60))%60)
  var hours = parseInt((diff/(1000*60*60))%24);

  if (hours < 10) {
      hours = "0" + hours;
    }
  if (mins < 10) {
      mins = "0" + mins;
    }
  if (sec < 10) {
      sec = "0" + sec;}
  if(now >= end1) {
    clearTimeout(interval);
    localStorage.setItem("end", null);
    localStorage.removeItem("end1");
    localStorage.clear();
    document.getElementById('divCounter').innerHTML = finishedtext;
    if(confirm("TIME UP!")) window.location.href= "result.php";
  } else {
      progressBar.value = progressBar.max - (end1-now);
      var value = hours+":" +mins + ":" + sec;
      localStorage.setItem("end1", end1);
      document.getElementById('divCounter').innerHTML = value;
  }
}
var interval = setInterval(counter, 1000);
</script>

I hope that helps. Don't hesitate to make your question more clear.
