new Date(); 当前系统的时间对象
var oBody=document.body; fnTime(); setInterval(fnTime,1000); function fnTime(){ //myTime typeof object var myTime=new Date(); //number var iYear=myTime.getFullYear();//年 var iMonth=myTime.getMonth()+1;//月 正常的月必须加1+ var iDate=myTime.getDate();//日 var iWeek=myTime.getDay();//周 var iHours=myTime.getHours();//小时 var iMinutes=myTime.getMinutes();//分 var iSeconds=myTime.getSeconds();//秒 if(iWeek===0){ iWeek="星期日"; }else if(iWeek===1){ iWeek="星期一"; }else if(iWeek===2){ iWeek="星期二"; }else if(iWeek===3){ iWeek="星期三"; }else if(iWeek===4){ iWeek="星期四"; }else if(iWeek===5){ iWeek="星期五"; }else if(iWeek===6){ iWeek="星期六"; } var str=""; str=iYear+"年"+iMonth+"月"+iDate+"日 "+" "+iWeek+toTwo(iHours)+":"+toTwo(iMinutes)+":"+toTwo(iSeconds); oBody.innerHTML=str; } //小于10补零 function toTwo(n){ if(n<10){ return "0"+n; }else{ return ""+n; } }
