日期和unix时间之间的时间，以及计时器倒计时

Question

As my title sais I want to make a timer that counts down the time between a unix time of the current time and a date (including hour minute and secounds) in js.

I don't have idea how to do it can you give me some help here?

Answer 1

  var now = new Date();
  var date = new Date(2012, 7, 9);
  var diff = new Date(date - now);

  var res = '';
  res += diff.getHours()   + 'h ';
  res += diff.getMinutes() + 'min ';
  res += diff.getSeconds() + 's';
