How to make countdown timer not reset when refresh the browser?

When i refresh the browser, the timer resets, so how to make it not reset? This is my code. Please check it.

<?php echo $waktune; ?> // You can change it into seconds

var detik = <?php echo $waktune; ?>;
if (document.images) {
    parselimit = detik
}
function begintimer() {
    if (!document.images)
        return
    if (parselimit < 12) {
        document.getElementById("servertime").style.color = "Green";
    }
    if (parselimit == 1) {
        document.getElementById("hasil").submit();
    } else {
        parselimit -= 1 curmin = Math.floor(parselimit / 60)
            cursec = parselimit % 60
        if (curmin != 0)
            curtime = curmin + ":" + cursec + ""else
            curtime = cursec + " detik"document.getElementById("servertime").innerHTML = curtime setTimeout("begintimer()", 1000)
        }
}

Solution

Try to use session storage :

// Store
sessionStorage.setItem("key", "value");
// Retrieve
document.getElementById("result").innerHTML=sessionStorage.getItem("key");

Update

Example :

<head>

</head>
<body>
    <div id="divCounter"></div>
    <script type="text/javascript">
    if (sessionStorage.getItem("counter")) {
      if (sessionStorage.getItem("counter") >= 10) {
        var value = 0;
      } else {
        var value = sessionStorage.getItem("counter");
      }
    } else {
      var value = 0;
    }
    document.getElementById('divCounter').innerHTML = value;

    var counter = function () {
      if (value >= 10) {
        sessionStorage.setItem("counter", 0);
        value = 0;
      } else {
        value = parseInt(value) + 1;
        sessionStorage.setItem("counter", value);
      }
      document.getElementById('divCounter').innerHTML = value;
    };

    var interval = setInterval(counter, 1000);
  </script>
</body>
