<div id="time"></div>

kindly me out........ in advance

here go. it's bit messy, in hurry, have tidy ;)

i used local storage store time , when refresh checks local storage , loads time that's left accordingly.

html:

<div id="time"></div> 

js:

function countdown(minutes, seconds) {   var currenttime;    function twodigits(n) {     return (n <= 9 ? '0' + n : n);   }    function updatetimer() {     msleft = endtime - (+new date);     time = new date(msleft);     hours = time.getutchours();     mins = time.getutcminutes();     currenttime = (hours ? hours + ':' + twodigits(mins) : mins) + ':' + twodigits(time.getutcseconds());     localstorage.setitem('timer', currenttime);     $('#time').text(currenttime);     countdowntimer = settimeout(updatetimer, time.getutcmilliseconds() + 500);   }    endtime = (+new date) + 1000 * (60 * minutes + seconds) + 500;   updatetimer(); }  if (localstorage.getitem('timer')) {   localtime = localstorage.getitem('timer');   var minutes = parseint(localtime.substr(0, localtime.indexof(':')));   var seconds = parseint(localtime = localtime.split(':')[1]);    countdown(minutes, seconds); } else {   countdown(120, 0); }
