本文實例為大家分享了js實現本地時間同步的具體代碼，供大家參考，具體內容如下
HTML代碼
<html><head> <title>時間</title> <meta charset="utf-8"></head><body onload="getTime()"> <span id="nowDateTimeSpan" ></span> </body></html>
js代碼
//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于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; }}以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
