js實現小時鐘,js中Date對象的使用?

標籤：div   date()   時間   ack   pop   doc   seconds   eva   minutes   

介紹一下js中Date對象的使用

dateObj = new Date()

dateObj = new Date(dateValue)

dateObj = new Date(year,month,date[,hours[,minutes[,seconds[,ms]]]]);

以下有一個小範例

<script type="text/javascript">function setTime(){//獲得如今的時間var now = new Date();  var year = now.getFullYear();  var month = now.getMonth();  month ++;  var date = now.getDate();  var day = now.getDay();  var hours = now.getHours();  var minute = now.getMinutes();  var second = now.getSeconds();var arr_week = new Array("星期一","星期二","星期三","星期四","星期五","星期六","星期日");var week = arr_week[day];  var time = year + "年" + month + "月" + date + "日 " + week + " " + hours + ":" +minute + ":" + second;var clock = document.getElementById("clock");clock.innerHTML ="目前時間: "+time;}//下載完畢後,每隔一秒更新一次時間window.onload = function(){window.setInterval("setTime()", 1000);}  </script>

顯示效果:
