JavaScript的倒計時新的日期

Question

我使用的JavaScript的倒計時器

<script type="text/javascript"> 
     $(function() { 
     var newYear = $(".HF").val(); 
      alert('hehe' + newYear); 
      $('#countdown').countdown({ until:newYear, format: 'DHMS', layout: 
'<div id="timer">' + '<hr />' + 
    '<div id="timer_days" class="timer_numbers">{dnn}</div>' + 
    '<div id="timer_hours" class="timer_numbers">{hnn}</div>' + 
    '<div id="timer_mins" class="timer_numbers">{mnn}</div>' + 
    '<div id="timer_seconds" class="timer_numbers">{snn}</div>' + 
'<div id="timer_labels">' + 
    '<div id="timer_days_label" class="timer_labels">days</div>' + 
    '<div id="timer_hours_label" class="timer_labels">hours</div>' + 
    '<div id="timer_mins_label" class="timer_labels">mins</div>' + 
    '<div id="timer_seconds_label" class="timer_labels">secs</div>' + 
'</div>' + 
'</div>' 
      }); 
     }); 
</script> 

它從隱藏字段的隱藏字段HF .The價值得到它，直到值是一個字符串10/22/2011。 ..但計時器顯示只剩下34分鐘，而它必須顯示2天和幾小時，剩下的一些分鐘..爲什麼？

Answer 1

的newYear串必須被轉換到一個Date對象：

var newYear = $(".HF").val(); 
newYear = new Date(newYear); // 10/22/2011 > Dat object of 22 Okt 2011
