HTML代码
1 2 3 4 5 6 7 8 9 | <html> <head> <title>时间</title> <meta charset="utf-8"> </head> <body onload="getTime()"> <span id="nowDateTimeSpan" ></span> </body> </html> |
js代码
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 | //时间 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(); // 如果分钟或小时的值小于10，则在其值前加0，比如如果时间是下午3点20分9秒的话，则显示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);//每一秒中重新加载startTime()方法 function checkTime(i){ if (i<10){ i="0" + i; } return i; } } |
