js 动态显示时间

方法一：

 

<SCRIPT language=JavaScript>
<!--

     tmpDate = new Date();
     date = tmpDate.getDate();
     month= tmpDate.getMonth() + 1 ;
     year= tmpDate.getYear();
     document.write(year);
     document.write("年");
     document.write(month);
     document.write("月");
     document.write(date);
     document.write("日 ");

     myArray=new Array(6);
     myArray[0]="星期日"
     myArray[1]="星期一"
     myArray[2]="星期二"
     myArray[3]="星期三"
     myArray[4]="星期四"
     myArray[5]="星期五"
     myArray[6]="星期六"
     weekday=tmpDate.getDay();
     if (weekday==0 | weekday==6)
     {
         document.write(myArray[weekday])
     }
     else
     {
         document.write(myArray[weekday])
     }
// -->

<SCRIPT language=Javascript1.2>
