//時間 function getTime(){ var ndate = new Date(); var nyear= ndate.getFullYear(); var nmonth = ndate.getMonth()+1; var nday = ndate.getDate(); var nhour = ndate.getHours(); var nminute = ndate.getMinutes(); var nsecond = ndate.getSeconds(); // 如果分鐘或小時的值小於10，則在其值前加0，比如如果時間是下午3點20分9秒的話，則顯示15：20：09 nmonth=checkTime(nmonth); nday=checkTime(nday); nminute=checkTime(nminute); nsecond=checkTime(nsecond); document.getElementById(‘nowDateTimeSpan‘).innerHTML=nyear+"-"+nmonth+"-"+nday+" "+nhour+":"+nminute+":"+nsecond; document.getElementById(‘nowDateTimeSpan1‘).innerHTML=nyear+"-"+nmonth+"-"+nday+" "+nhour+":"+nminute+":"+nsecond; document.getElementById(‘nowDateTimeSpan2‘).innerHTML=nyear+"-"+nmonth+"-"+nday+" "+nhour+":"+nminute+":"+nsecond; document.getElementById(‘nowDateTimeSpan3‘).innerHTML=nyear+"-"+nmonth+"-"+nday+" "+nhour+":"+nminute+":"+nsecond; document.getElementById(‘nowDateTimeSpan4‘).innerHTML=nyear+"-"+nmonth+"-"+nday+" "+nhour+":"+nminute+":"+nsecond; //setTimeout(‘getTime()‘,1000);//每一秒中重新加載startTime()方法 function checkTime(i){ if (i<10){ i="0" + i; } return i; } }
